Brenda Gantt Orange Slice Cake Recipe

Brenda Gantt's Orange Slice Cake is the crown jewel of Southern holiday baking — a magnificently dense, deeply moist cake packed with chewy candy orange slices, sugared dates, crunchy pecans, and sweet shredded coconut, all baked low and slow until the top forms a beautiful golden crust and the inside stays irresistibly tender. It's finished with a warm orange sugar glaze that's poured over while still hot, soaking down through the cake to sweeten every layer. This is not a delicate everyday dessert — it's a statement cake, the kind that gets passed around the holiday table twice, requested by name every year, and remembered decades later. Serve it in thick, generous slices alongside strong black coffee or sweet iced tea, and don't be surprised when the pan is empty before the evening is over.

Ingredients
  

Group 1 — The Cake Batter
  • 1 cup Salted butter, softened 2 sticks; must be room temperature — leave out 2 hours before baking; do not microwave to soften
  • 2 cups Granulated white sugar Do not substitute brown sugar — it changes the texture and adds unwanted moisture
  • 4 Large eggs, room temperature Cold eggs cause the batter to seize; set out 30 minutes before using
  • 1 tsp Baking soda Do not substitute baking powder — the acid-base reaction with buttermilk is essential
  • 1 cup Whole buttermilk Whole buttermilk gives the best tender crumb; substitute: 1 tbsp white vinegar in 1 cup regular milk, wait 5 minutes
  • 3 cups White Lily all-purpose flour (plus extra for dusting) White Lily's lower protein content gives a more tender crumb; any all-purpose flour works; spoon into measuring cup, do not pack
Group 2 — The Mix-Ins (Tossed in Flour Before Adding)
  • 1 lb Candy orange slices, chopped into small pieces The star ingredient — sugary jellylike candies, not fresh oranges; cut into ½-inch pieces; flour your knife to prevent sticking
  • 1 lb Sugared chopped dates Buy pre-chopped sugared dates for convenience; the sugar coating prevents clumping
  • 1 cup Sweetened shredded coconut Bagged sweetened coconut, not frozen or fresh; adds chew and moisture
  • 1 cup Pecans, roughly chopped Buy pre-chopped or chop yourself; toasting optional but deepens flavor; walnuts work as a substitute
Group 3 — The Orange Sugar Glaze
  • 2 cups Granulated white sugar Combined with OJ to form a thick syrup; do not reduce — the glaze needs this volume to penetrate and coat the full cake
  • ¾ cup Orange juice, pulp-free Fresh-squeezed gives the brightest flavor; good-quality store-bought works fine; do not substitute other citrus

Equipment

  • 1 Stand mixer or hand mixer Stand mixer handles the thick batter much more easily; use medium speed
  • 1 10–12 cup tube pan or bundt pan The center tube is critical — it helps the dense batter cook through evenly
  • 1 Large mixing bowl (4-quart or larger) You need room to fold in 3 pounds of mix-ins without overflowing
  • 1 Medium heavy-bottom saucepan For the glaze; heavy-bottom prevents burning the sugar syrup
  • 1 Long wooden skewer or cake tester Standard toothpicks are too short for this tall, dense cake
  • 1 Pastry brush (new or food-only) For applying the glaze; a 1-inch brush covers the curved surfaces evenly
  • 1 Parchment paper Cut a circle to line the bottom of the tube pan for clean unmolding
  • 1 Oven thermometer Recommended — oven accuracy is critical at 250°F; even a 25° variance matters
  • 1 Wooden spoon For hand-mixing the thick batter after adding mix-ins; a spatula can crack
  • 1 Small bowl For mixing baking soda into buttermilk before adding to batter

Method
 

Phase 1 — Prep Work: Pan, Oven, and Mix-Ins
  1. Step 1 — Prepare the pan and preheat the ovenSet your oven to 250°F — and if you have an oven thermometer, now is the time to use it, because precision matters here. Grease your tube or bundt pan generously with butter or shortening, making sure to coat every crevice, then dust it lightly with flour and tap out the excess. Cut a circle of parchment paper to fit the bottom of the pan and press it in place — this extra step ensures the cake releases cleanly after its long bake. A cake this dense and full of sticky candy needs all the help it can get when it comes time to unmold.
  2. Step 2 — Flour the mix-insIn a large bowl, combine the chopped orange slice candies, chopped dates, shredded coconut, and pecans. Sprinkle a couple of tablespoons of your measured flour over the mixture and toss everything together with your hands until the candy and date pieces are lightly coated all over. This flouring step is one of the most important techniques in this recipe — it prevents the heavy, sticky mix-ins from sinking straight to the bottom of the batter during the long bake, and it helps them suspend evenly throughout the finished cake. Don't skip it, and don't be shy — every piece should have a light, visible coating.
Phase 2 — Build the Batter
  1. Step 3 — Cream the butter and sugarPlace the room-temperature butter in the bowl of your stand mixer fitted with the paddle attachment. Add the sugar and beat on medium speed for a full 3 minutes, until the mixture is noticeably pale, light, and fluffy. You should see the color shift from yellow to a creamy off-white and the texture become almost cloud-like — this process aerates the fat, which is what gives even a dense cake like this one its lift and tenderness. If your butter wasn't truly at room temperature, you'll struggle to get here; don't rush this step.
  2. Step 4 — Add the eggs one at a timeWith the mixer running on medium-low, add the eggs one at a time, allowing each egg to fully incorporate before adding the next — about 30–45 seconds per egg. The batter may look slightly curdled or broken between additions, and that's completely normal; it will come together as you continue. Room-temperature eggs blend more seamlessly into the fat than cold eggs do, which is why that 30-minute rest on the counter matters. By the time the fourth egg is incorporated, your batter should look smooth and slightly glossy.
  3. Step 5 — Prepare and add the buttermilk mixtureIn a small bowl, stir the baking soda into the buttermilk with a fork — it will foam up dramatically, nearly doubling in volume, and that reaction is exactly what you want. This is the leavening engine of the cake: the acidic buttermilk reacts with the baking soda to create carbon dioxide, which gives the dense batter its only source of lift and keeps the crumb tender rather than tough. Pour the foamy buttermilk mixture into the butter-egg batter and mix on low just until combined — the batter will look slightly curdled at this point, but trust the process.
  4. Step 6 — Combine the wet and dry ingredientsPour the wet batter over the flour-coated mix-in bowl, then add the remaining flour on top of everything. Switch to a sturdy wooden spoon and fold everything together by hand until just combined — you're looking for no dry flour pockets, but you're not trying to smooth the batter out completely. This is a thick, heavy batter, and it will resist stirring; use firm, deliberate strokes from the bottom of the bowl upward rather than vigorous beating. Overmixing at this stage develops gluten and can toughen the crumb, so stop as soon as the dry streaks disappear.
Phase 3 — Bake the Cake
  1. Step 7 — Fill the pan and bakeScoop and spoon the thick batter into your prepared pan, pressing it gently with the back of a spoon to fill any air pockets and level the surface. The pan will be very full — this is expected for a cake this dense and loaded. Place it in the center rack of your preheated 250°F oven and do not open the door for the first 2 hours. The slow, low heat is the whole secret to this cake's moist interior — raising the temperature to speed things up will burn the exterior before the center is cooked through. Begin checking for doneness after 2½ hours by inserting a long skewer into the deepest part of the cake; it should come out clean, without wet batter clinging to it. The top should be deep golden brown with a lightly crusty surface.
Phase 4 — Glaze and Rest (This Is What Makes It Exceptional)
  1. Step 8 — Make the glaze while the cake bakesAbout 20 minutes before you expect the cake to be done, combine the 2 cups of sugar and ¾ cup of orange juice in a medium saucepan over medium heat. Stir constantly as the mixture comes to a boil, then continue to cook for 1 full minute at a rolling boil until it thickens into a syrup — it should coat the back of a spoon lightly. Remove from heat and keep warm; you need to apply the first half of the glaze while both the cake and the syrup are still hot, so timing matters here. If your glaze cools and firms up before you're ready, reheat it gently over low heat.
  2. Step 9 — Poke and glaze in the panThe moment the cake comes out of the oven, use your long skewer to poke holes all over the top surface — aim for 20–30 holes spaced evenly across the cake, going deep. These holes are the channels that carry the glaze down into the interior of the cake, flavoring and moistening it from the inside out rather than just coating the surface. Pour exactly half the warm glaze slowly and evenly over the hot cake while it's still in the pan, letting it seep down into the holes. Leave the cake in the pan, cover loosely with a clean towel, and allow it to rest for a minimum of 2 hours — or overnight, which is even better.
  3. Step 10 — Unmold, glaze the outside, and rest againAfter the resting period, run a thin knife or offset spatula gently around the edges of the cake, then carefully invert it onto a wire rack or serving plate. Peel away the parchment paper from the bottom. Reheat the remaining glaze in the saucepan over low heat until it's warm and pourable again. Using your pastry brush, paint the warm glaze over all the exposed surfaces of the cake — the sides, the bottom (now the top), and any crevices — building up a thin, sticky, shiny seal all the way around. This outer glaze layer is what preserves the moisture of the cake for days and gives it that beautiful, lacquered appearance. Let the finished cake cool completely at room temperature before slicing — at least another 2 hours, or until the next morning.

Notes

  • The low-and-slow bake is non-negotiable: 250°F for 2½–3½ hours is the technique that defines this cake. At higher temperatures, the sugar-heavy candy and dates scorch before the center cooks through. Resist any urge to raise the heat — buy yourself a magazine, make a pot of coffee, and wait it out. The result is worth every hour.
  • Flour your knife when chopping the candy: Orange slice candies and dates are intensely sticky. Dip your knife in a small bowl of all-purpose flour between every few cuts to keep the blade from gumming up and the pieces from welding back together. Working quickly also helps — candy softens from the warmth of your hands. Alternatively, freeze the candy slices for 15 minutes before cutting to firm them up.
  • Room temperature matters for everything: Butter that isn't truly soft will never cream properly, and cold eggs will cause the fat to seize and the batter to look broken in a way that doesn't fully recover. Give yourself time — set the butter and eggs out a full hour before you plan to start mixing.
  • How to know it's done: The top of the cake should be deep golden brown and feel slightly firm, not soft, when you press it gently in the center. A long skewer should come out clean — some sticky residue from candy is expected and fine, but raw wet batter means it needs more time. Because of the candy and dates, doneness takes practice to read; when in doubt, give it another 20 minutes.
  • Common mistake — skipping the overnight rest: Many first-time bakers slice into this cake after just a couple of hours and find it stickier and more fragile than expected. The overnight rest in the pan after the first glaze application is when the magic happens: the syrup penetrates deep into the crumb, the structure sets, and the flavors knit together. Brenda Gantt is emphatic about this — wrap it up, go to bed, and cut it in the morning.
  • Flavor variations:
    • Bourbon Orange Slice Cake: Replace ¼ cup of the orange juice in the glaze with good bourbon for a warm, smoky-sweet depth that pairs beautifully with the citrus candy.
    • Chocolate Chip Orange Slice Cake: Fold in ½ cup of mini dark chocolate chips with the mix-ins for a bittersweet contrast to the candy's sweetness.
    • Walnut & Cranberry Version: Swap pecans for walnuts and add ½ cup dried cranberries to the mix-in bowl for a tangier, more tart holiday profile.
    • Lemon Glaze Twist: Replace orange juice in the glaze with fresh lemon juice and add 1 tsp lemon zest — the sharper citrus cuts the sweetness beautifully for those who find the original very rich.
  • Make-ahead instructions: This cake is at its absolute best made 1–3 days in advance. Bake, glaze, let rest overnight, then wrap tightly in plastic wrap and store at room temperature. The flavor deepens considerably by day two, as the glaze continues to penetrate and the mix-ins become more integrated into the crumb.
  • Storage: Wrap the fully cooled, glazed cake tightly in plastic wrap, then a layer of aluminum foil. Store at room temperature for up to 5 days, refrigerated for up to 3 weeks. Do not store at room temperature in warm or humid climates — refrigerate instead.
  • Reheating: This cake is best served at room temperature, not warm. If refrigerated, remove it from the fridge 30–45 minutes before serving and allow it to come to room temperature — cold temperatures firm up the butter and candy, making the crumb feel denser than it truly is. Individual slices can be very briefly microwaved (10 seconds maximum) if needed.
  • Freezing instructions: This cake freezes exceptionally well. Wrap the whole glazed cake (or individual slices) tightly in two layers of plastic wrap, then aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator, then bring to room temperature before serving. The glaze seals the cake so effectively that freezing barely affects the texture or moisture.
  • Dietary adaptations:
    • Gluten-free: Substitute a 1:1 gluten-free all-purpose flour blend (such as Bob's Red Mill or King Arthur Measure for Measure); results will be slightly denser but still delicious.
    • Nut-free: Omit pecans entirely, or replace with toasted pumpkin seeds (pepitas) for crunch without tree nuts.
    • Coconut-free: Simply omit the coconut — replace with an extra ½ cup of chopped pecans or dates to maintain the textural variety.
    • Dairy-free: Use vegan butter (Earth Balance) and non-dairy buttermilk (1 cup oat milk + 1 tbsp apple cider vinegar, rested 5 minutes).
  • Serving suggestions: Serve in thick slices with a strong pot of black coffee, hot tea, or sweet Southern-style iced tea. For a dessert platter presentation, arrange slices alongside a small dish of fresh whipped cream or a scoop of vanilla bean ice cream — the cool creaminess balances the richness beautifully. This cake also makes an extraordinary homemade gift: wrap a half-loaf in wax paper, tie with twine, and tuck a handwritten card with the recipe inside.
  • Scaling and yield note: This recipe makes one large tube or bundt pan cake, yielding 16–20 slices depending on how generously you cut. It does not scale down easily due to the low-temperature baking method and the ratio of mix-ins to batter — smaller versions tend to dry out or not set properly. If you want to make multiple cakes (ideal for gifting), simply make the full recipe multiple times rather than attempting to double the batter in one mixing.
