Ingredients for Brenda Gantt Orange Slice Cake

Pantry staples, citrus, and a touch of nostalgia make this cake unforgettable.

Ingredient Amount Notes
Navel Oranges 🍊 2 whole Unpeeled, thinly sliced
All-Purpose Flour 🌾 3 cups Sifted before measuring
Granulated Sugar 🍚 2 cups Divided for cake and glaze
Large Eggs 🥚 4 whole Room temperature preferred
Vegetable Oil 🫒 1 cup Neutral flavor like canola
Buttermilk 🥛 1 cup Full-fat for richness
Baking Soda 🧂 1 tsp Ensures proper rise
Vanilla Extract 💧 2 tsp Pure extract recommended
Salt 🧂 ½ tsp Balances sweetness
Ground Cinnamon 🌿 1 tsp Adds warm spice notes
Unsalted Butter 🧈 ½ cup For greasing pan
Powdered Sugar 🧂 ¼ cup Optional for dusting

The oranges are everything. Navel oranges have the perfect sweetness and thin skins that soften beautifully during baking. Most supermarkets carry them year-round, but winter months bring the juiciest fruit. The buttermilk adds that signature Southern tang—full-fat from the dairy section works best. For the flour, King Arthur or Pillsbury are reliable brands that give consistent results every time.

No buttermilk? Stir 1 tbsp lemon juice or vinegar into regular milk and let it sit 5 minutes. Swapping vegetable oil for melted butter changes the texture slightly but works in a pinch. Want extra citrus flavor? Zest one orange and add it to the batter. The powdered sugar topping is optional—this cake is plenty sweet without it (and honestly tastes more authentic without).

This cake stays moist for 3-4 days at room temperature in an airtight container. For longer storage, wrap slices individually and freeze for up to 3 months. The flavors actually deepen after a day, making it perfect for making ahead.

Step-by-Step Instructions for Orange Slice Cake

This Southern classic comes together with simple steps and delivers impressive results every time.

Step 1: Prepare the Oranges and Pan

Thinly slice the 2 whole Navel Oranges unpeeled into ⅛-inch rounds, discarding the very ends. This thinness ensures the slices cook through and soften beautifully in the cake. Set the slices aside while you prepare the pan.

Generously grease a 10-inch tube pan or Bundt pan with 0.5 cup Unsalted Butter, making sure to coat every crevice. I use a pastry brush to get into all the details of the pan. This prevents sticking and helps the cake release cleanly after baking.

Step 2: Make the Cake Batter

In a large bowl, whisk together the 3 cups All-Purpose Flour, 1 tsp Baking Soda, 0.5 tsp Salt, and 1 tsp Ground Cinnamon. Sifted flour ensures a light, even crumb in the finished cake. In a separate bowl, combine 2 cups Granulated Sugar with 1 cup Vegetable Oil and beat until well mixed.

Add the 4 whole Large Eggs one at a time, beating well after each addition. Then stir in 1 cup Buttermilk and 2 tsp Vanilla Extract. The buttermilk adds richness and tenderness to this old-fashioned cake. Fold the dry ingredients into the wet mixture until just combined—overmixing creates a tough cake.

Step 3: Layer and Bake

Pour half of the batter into the prepared pan, spreading it evenly. Arrange half of the orange slices in a single layer over the batter. Pour the remaining batter over the oranges, then top with the remaining orange slices, overlapping slightly if needed.

Bake at 325°F for 1 hour to 1 hour 15 minutes or until a toothpick inserted near the center comes out clean. The low and slow baking ensures the cake cooks through without browning too quickly. The orange slices will become tender and slightly caramelized.

Step 4: Cool and Serve

Let the cake cool in the pan for 15 minutes, then invert it onto a wire rack to cool completely. This brief cooling period helps the cake set enough to release cleanly from the pan without breaking apart.

Once completely cooled, dust with 0.25 cup Powdered Sugar if desired. The orange slices create a beautiful, moist cake with a perfect balance of sweetness and citrus flavor. Serve at room temperature for the best texture and flavor.

Pro Tips For Making Brenda Gantt Orange Slice Cake

  • Use Thin Orange Slices: Slice your navel oranges paper-thin—about 1/8 inch thick—so they soften fully while baking and don’t leave chewy bits in the finished cake.
  • Room Temp Eggs: Pull your large eggs out 30 minutes before mixing, because I learned the hard way that cold eggs can cause the oil to clump instead of emulsifying smoothly.
  • Don’t Overmix Batter: Stir just until the flour disappears—any longer and you’ll end up with a tough cake instead of that tender, moist crumb Brenda’s recipe is known for.
  • Preheat Properly: Give your oven a full 15 minutes to reach 325°F before the pan goes in, or the cake may dome unevenly and brown too fast on the outside.

Perfect Pairings for This brenda gantt orange slice cake

Beverage Pairings

This cake’s bright citrus flavor pairs beautifully with a hot cup of coffee—the bitterness balances the sweetness perfectly. I love it with a medium roast like Starbucks’ Breakfast Blend. For tea lovers, a black tea such as Earl Grey adds a complementary bergamot note. 🍷

Dessert Wine

A chilled glass of Moscato d’Asti enhances the orange notes with its fruity, slightly effervescent profile. For something stronger, try a late-harvest Riesling—its honeyed sweetness mirrors the cake’s citrus glaze without overpowering it.

Fresh Toppings

Serve slices with a dollop of whipped cream or a scoop of vanilla ice cream to add creaminess. Fresh berries like raspberries or blackberries provide a tart contrast. I often sprinkle toasted pecans on top for a Southern crunch. 💫

Savory Balance

For brunch, pair this cake with sharp cheddar cheese and smoked ham to create a sweet-savory harmony. The saltiness of the cheese cuts through the cake’s richness, making each bite more satisfying.

Seasonal Variations

In summer, serve with lemon sorbet for a refreshing citrus duo. During the holidays, a spiced chai latte complements the cinnamon in the batter. Honestly, this cake works year-round with the right pairing.

Frequently Asked Questions

1

Do I have to use Navel oranges?

Navel oranges are ideal for their sweet flavor and thin skin, but you can use other varieties. Avoid thick-skinned oranges like Valencia as they may not soften properly during baking.

2

Why does the cake bake at such a low temperature?

The 325°F oven ensures even cooking without over-browning. This slow bake allows the orange slices to tenderize and the center to set perfectly without drying out.

3

Can I make this in a regular cake pan?

A tube or Bundt pan is recommended for even heat distribution. If using a 9×13-inch pan, reduce baking time to 45-50 minutes and watch closely for doneness.

4

How do I prevent the cake from sticking?

Grease the pan thoroughly with butter, getting into all the crevices. Let the cake cool for 15 minutes before inverting to allow it to set and release cleanly.
