Sticky Pecan Upside Down Bundt Cake
This pecan upside down Bundt cake starts with a buttery brown sugar pecan topping that bakes under a tender vanilla cake, then gets flipped so the sticky nuts crown the top. It looks dramatic but comes together in one pan with no fussy layering.
The cake itself is soft and rich from buttermilk, with a tight crumb that holds the pecans in place when you invert it. It’s the kind of dessert that feels special enough for a holiday table but easy enough to make on a Sunday afternoon.
What Makes This Cake So Good
The brown sugar and butter create a deep, almost toffee-like glaze that sets up just enough to be sticky, not soggy. The pecans toast right in the pan, so they end up crunchy and fragrant.
The cake underneath is buttery and tender, with a fine crumb that doesn’t fall apart when you flip it. Buttermilk keeps it moist for days, and a good dose of vanilla rounds out the sweetness.
It uses one Bundt pan and no electric mixer beyond a hand whisk, so cleanup is quick. The hardest part is waiting for it to cool before you turn it out.
Ingredients
- 1/2 cup unsalted butter, melted: for the topping
- 1 cup packed light brown sugar: creates the sticky caramel layer
- 1/4 cup heavy cream: keeps the topping smooth and glossy
- 1/4 teaspoon fine sea salt: balances the sweetness
- 1 1/2 cups pecan halves: toast right in the pan as the cake bakes
- 2 1/2 cups all-purpose flour: spooned and leveled, do not pack
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine sea salt: for the cake batter
- 1 cup unsalted butter, softened: for the cake
- 1 1/2 cups granulated sugar
- 3 large eggs: at room temperature
- 2 teaspoons vanilla extract
- 1 cup buttermilk: at room temperature
Variations / Substitutions
- Swap pecans for walnuts: the flavor is earthier and the texture stays similar.
- Skip the heavy cream: use whole milk or half-and-half for a slightly thinner caramel.
- Add 1/4 teaspoon cinnamon: to the dry ingredients for a warm spice note.
- Use dark brown sugar: for a stronger molasses flavor in the topping.
- For a dairy-free version: replace butter with plant-based sticks and use oat milk plus a teaspoon of lemon juice for the buttermilk.
If you want a nutty cake without the flip, the Pecan Sour Cream Coffee Cake is a great one to try.
How to Make Pecan Upside Down Bundt Cake
Step 1: Make the Sticky Pecan Base
Preheat your oven to 350°F (175°C). Melt the 1/2 cup butter in a small saucepan over medium heat. Stir in the 1 cup brown sugar, 1/4 cup heavy cream, and 1/4 teaspoon salt. Keep stirring until the sugar dissolves and the mixture is smooth, about 2 minutes.
The caramel will look glossy and deep amber, with a smell like warm toffee. Don’t let it boil hard, a gentle bubble is fine.
Pour the mixture into an ungreased 10-cup Bundt pan and arrange the pecan halves evenly across the bottom. Set the pan aside. The caramel will firm up slightly while you make the batter, and it will release cleanly when you flip the cake later.
Step 2: Whisk the Dry Ingredients
Whisk together the 2 1/2 cups flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon salt in a medium bowl. Spend a full 30 seconds whisking to make sure the leaveners are evenly distributed.
The mixture should be uniform with no streaks of baking soda. This step keeps your cake from having odd tunnels or uneven rise.
Set the bowl aside while you work on the wet ingredients. This is a quick step, but don’t rush it, lumpy leavening is a common culprit for dense spots.
Step 3: Cream the Butter and Sugar
Beat the 1 cup softened butter and 1 1/2 cups granulated sugar with a hand mixer on medium speed until the mixture turns pale and fluffy, about 3 minutes. Scrape the sides of the bowl a few times.
The color will lighten from yellow to almost white, and the texture becomes thick and creamy.
Proper creaming gives the cake its lift and tender crumb. If the butter is too cold, it won’t incorporate enough air, so make sure it’s truly room temperature.
Step 4: Finish the Cake Batter
Add the 3 eggs one at a time, beating well after each, then mix in the 2 teaspoons vanilla. With the mixer on low, add half the flour mixture, then all of the 1 cup buttermilk, then the remaining flour, mixing just until each addition disappears. The total mixing time here should be about 1 minute.
Scrape the bowl with a spatula and give everything one final stir by hand to catch any unmixed pockets. The batter will be thick and ribbon-like.
Overmixing at this stage can make the cake tough, so stop as soon as no dry streaks remain. This gentle hand gives you a soft, even crumb.
Step 5: Bake Until Golden
Pour the batter over the pecan-topped caramel in the Bundt pan and smooth the top. Bake for 45 to 50 minutes, until the cake is deep golden and a toothpick inserted near the center comes out clean.
The kitchen will smell incredible. The cake will have risen and pulled slightly away from the sides of the pan. A few cracks on the surface are totally normal and will be hidden when you flip it.
Ovens vary, so start checking at the 40-minute mark. If the top browns too quickly, tent it loosely with foil.
Step 6: Cool and Turn Out the Cake
Let the cake cool in the pan on a wire rack for exactly 10 minutes, no longer, or the caramel may harden and stick. Run a thin knife around the center tube and outer edges if needed, then place your serving plate upside down over the pan. Holding both firmly, flip the pan and plate together. Lift the pan off slowly.
As you lift the pan, you’ll see the glossy pecans and hear a slight crackle as the caramel releases. The pecan layer will be shiny and deep amber, with a little caramel dripping down the sides.
If any pecans stick to the pan, press them back onto the cake right away while the caramel is still warm and tacky. Let the cake cool completely before slicing, so the caramel sets into a soft but sliceable layer.
A Few Notes for a Perfect Flip
- Bring all cold ingredients to room temperature for a smooth batter that rises evenly.
- Set a timer for the 10-minute cool before flipping. If you forget and the cake sticks, reheat the pan in a 200°F oven for 5 minutes to soften the caramel.
- For a nuttier taste, toast the pecans before making the topping: spread them on a sheet pan and bake at 350°F for 5 minutes, then cool.
- Wipe your knife between slices to keep the sticky pecan layer intact.
Bake times can shift with the pan you use:
| Pan size | Bake time |
|---|---|
| 10-cup Bundt | 45 to 50 mins |
| 12-cup Bundt | 40 to 45 mins |
| 9-inch round | 35 to 40 mins |
Keeping the Cake Fresh
Store leftover cake covered at room temperature for up to 2 days, or refrigerate for up to 5 days. The caramel softens at room temp, so let it sit out for 30 minutes before serving if chilled.
Reheat individual slices in the microwave for 15 seconds to rewarm the topping.
What to Serve With This Bundt
A scoop of vanilla ice cream melts into the warm caramel for a classic combination. Cold brew coffee cuts the sweetness, or a simple dollop of lightly whipped cream adds richness without overpowering the pecans.
Frequently Asked Questions
Can I use a regular cake pan instead of a Bundt?
Yes, a 9-inch round pan works well. Reduce the baking time by about 10 minutes and keep a close eye on the toothpick test.
Can I make the topping ahead of time?
Yes, prepare the caramel, pour it into the pan with the pecans, and refrigerate overnight. Bring it to room temperature before adding the batter and baking.
Why did the caramel turn grainy?
Grainy caramel usually means the sugar didn’t dissolve fully. Stir the mixture over medium heat until it looks completely smooth, not just melted, before pouring it into the pan.
My cake didn’t rise properly, what went wrong?
Check that your baking powder and soda are fresh. Also, overmixing the batter or using cold ingredients can prevent a good rise.
Can I freeze this cake?
Yes. Wrap the cooled cake in a double layer of plastic and freeze for up to 2 months. Thaw at room temperature and warm slices briefly before serving.
