This blackberry cornmeal upside-down cake is a rustic, lightly sweet dessert that blends the comforting texture of cornbread with the bright, juicy flavor of baked blackberries. The berries caramelize gently with sugar at the bottom of the pan, creating a beautiful topping once the cake is inverted. With a tender crumb and a balance of sweetness and tartness, this cake works just as well for brunch with coffee as it does for dessert.

Why You’ll Love This Recipe

This cake is perfect if you enjoy desserts that aren’t overly sweet but still feel satisfying. The cornmeal gives the cake a pleasant texture that’s slightly hearty yet soft, while the blackberries add natural sweetness and a vibrant color once the cake is flipped.

Another reason this recipe stands out is its versatility. It can be served warm or at room temperature, making it a great choice for brunch gatherings, afternoon snacks, or light desserts after dinner. The combination of fruit and cornmeal creates a unique flavor that feels both comforting and elegant.

It’s also a great way to use berries that might be slightly overripe. As they bake, the fruit softens and becomes jammy, forming a naturally sweet topping without requiring complicated preparation.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 tablespoons turbinado sugar or granulated sugar
2 1/2 to 3 cups fresh blackberries (about 12 ounces)
1/2 cup granulated sugar plus 1 tablespoon
1 cup all-purpose flour, plus extra for dusting the pan
1 cup cornmeal (medium or fine grain)
1 teaspoon baking soda
1/2 teaspoon salt
1/2 cup unsalted butter, softened at room temperature
2 large eggs
1 teaspoon vanilla extract
1 cup buttermilk, well shaken
vanilla whipped cream or powdered sugar for serving (optional)

Directions

Preheat the oven to 350°F (175°C). Grease an 8-inch or 9-inch springform pan with butter. Place a round piece of parchment paper on the bottom and butter the parchment as well. Lightly dust the inside of the pan with flour and tap out any excess.

Sprinkle the turbinado sugar evenly across the bottom of the prepared pan. Arrange the blackberries over the sugar in a single layer to create the base of the upside-down topping.

In a medium bowl, whisk together the all-purpose flour, cornmeal, baking soda, and salt until evenly combined.

In a large mixing bowl, beat the butter with the 1/2 cup plus 1 tablespoon of sugar using an electric mixer. Continue beating for about 4 to 5 minutes until the mixture becomes light, creamy, and fluffy.

Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract until fully incorporated.

Gradually add the flour mixture and buttermilk to the batter in three alternating batches. Begin with the flour mixture, then add buttermilk, continuing until everything is incorporated. Mix just until combined to avoid overworking the batter.

Pour the batter gently over the blackberries in the pan. Smooth the top with a spatula without pressing down on the berries.

Place the pan in the center of the oven and bake for about 40 minutes, or until a cake tester inserted into the cake portion comes out clean.

Remove the cake from the oven and allow it to cool for 15 to 20 minutes. Carefully run a knife around the edge of the pan to loosen the cake.

Release the springform ring and invert the cake onto a serving plate or cutting board. Gently peel off the parchment paper to reveal the blackberry topping.

Serve warm or at room temperature with vanilla whipped cream or a light dusting of powdered sugar if desired.

Storage/Reheating

Store leftover cake in an airtight container at room temperature for up to 1 day. For longer storage, refrigerate it for up to 4 days.

If refrigerated, allow the cake to come to room temperature before serving or warm individual slices briefly in the microwave for about 15 to 20 seconds.

You can also reheat slices in a low oven at 300°F (150°C) for about 8 minutes to restore the cake’s soft texture.
