Step 1: Prepare to Bake
-
Preheat your oven to 375°F (190°C).
-
Grease a 9-inch round cake pan and line the bottom with a circle of parchment paper, then grease the paper for foolproof release.
Step 2: Combine the Dry Ingredients
-
In a large mixing bowl, whisk together theĀ flour, cornmeal, sugar, baking powder, and salt. This ensures the leavening is evenly distributed for a perfect rise.
Step 3: Whisk the Wet Ingredients
-
In a separate medium bowl, whisk theĀ sour cream, melted butter, eggs, and vanilla extractĀ until the mixture is smooth and completely combined.
Step 4: Bring the Batter Together
-
Pour the wet ingredients into the dry ingredients. Using a spatula,Ā gently foldĀ until the flour is just incorporated and no dry streaks remain. Be careful not to overmixāa few lumps are okay!
-
In a small bowl, stir together theĀ 2 tablespoons of sugar and 1 teaspoon of cinnamon. Add theĀ 1/4 cup of melted butterĀ and mix until it forms a loose, sandy paste.
Step 6: Assemble and Swirl
-
Pour the batter into your prepared pan and smooth the top with the spatula.
-
Drizzle the cinnamon-sugar butter mixture evenly over the entire surface.
-
Use a knife or a toothpick to gentlyĀ swirl the topping into the batter, creating beautiful marbled patterns.
Step 7: Bake to Perfection
-
Bake forĀ 25-30 minutes, or until the edges are golden and a toothpick inserted into the center of the cake comes out clean.
-
Let the cake cool in the pan on a wire rack forĀ at least 15 minutes.
-
Carefully run a knife around the edge, then invert the cake onto the rack, remove the parchment paper, and flip it right-side-up to cool completely.
-
Slice and serve at room temperature for the best flavor and texture.
š” Bakerās Notes & Tips
-
Pan Choice:Ā A 9-inch square baking pan can also be used. The baking time may be slightly less, so start checking at 20 minutes.
-
Donāt Overmix:Ā The key to a tender cake is mixing the batter until the ingredients areĀ justĀ combined. Overmixing develops gluten and can make the cake tough.
-
Flavor Variations:Ā Add the zest of one orange to the wet ingredients for a bright, citrusy twist, or fold 1/2 cup of fresh blueberries into the batter at the end.
-
Serving Suggestion:Ā This cake is wonderful on its own, but itās truly sublime when served warm with a dollop of whipped cream or a scoop of vanilla ice cream.
