Apple Cinnamon Crumble Cake

Ingredients

• 2 1/4 cups all-purpose flour
• 1 teaspoon baking powder
• 1 teaspoon salt
• 1 cup granulated sugar
• 1/2 cup unsalted butter, softened
• 2 large eggs
• 2 teaspoons vanilla extract
• 2 cups diced apples (Granny Smith or other sweet-tart variety)
• 1 teaspoon ground cinnamon
• 1/4 cup rolled oats
• 1/4 cup brown sugar
• 1/2 cup chopped walnuts (optional)

Instructions

Preheat and Prep

Preheat the oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper.

Make the Cake

In a medium bowl, whisk together flour, baking powder, and salt. Set aside.

In a large bowl, use an electric mixer to beat the sugar and butter until light and fluffy. Beat in eggs one at a time, followed by vanilla extract. With the mixer on low speed, gradually add the flour mixture and mix until just combined.

Fold in the diced apples and cinnamon until they're evenly distributed throughout the batter.

Divide the batter evenly between the prepared pans and smooth the tops.

Bake the Cakes

Bake for 35-40 minutes or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Make the Crumble Topping

In a small bowl, mix together rolled oats, brown sugar, and chopped walnuts (if using). Add the softened butter and use your fingers or a pastry blender to work it into the dry ingredients until the mixture resembles coarse crumbs.

Assemble and Serve

Once the cakes are completely cool, place one cake layer on a serving plate or cake stand. Top with the crumble topping, followed by the second cake layer. Drizzle with caramel sauce or whipped cream, if desired.

Serve warm or at room temperature, dusting with powdered sugar just before serving.

Note: This recipe combines elements of an apple crumble and a cinnamon coffee cake to create a unique dessert experience. The crunchy oat topping adds texture and flavor contrast to the moist and flavorful cake.
