Jersey Apple Cake with Brown Butter Crumble and Vanilla Bean Yogurt

Preheat oven to 350°F (175°C). Grease and flour a 9-inch springform pan.

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

In a separate large bowl, cream together the brown sugar and softened butter until light and fluffy. Beat in the egg, then stir in applesauce and vanilla extract.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the diced apples.

Pour batter into the prepared pan and spread evenly.

Prepare the crumble: In a medium saucepan over medium heat, melt the butter and cook, swirling occasionally, until it turns golden brown and has a nutty aroma (about 5-7 minutes). Remove from heat.

In a separate bowl, combine flour, oats, and brown sugar for crumble. Pour the browned butter into the flour mixture and mix with a fork until the crumble forms.

Sprinkle the crumble evenly over the cake batter.

Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let cool in the pan for 10 minutes before removing the sides of the springform pan.

Serve warm or at room temperature with a dollop of vanilla bean yogurt.
