Brown Butter Apple Cake for 12 Slices

Instructions:

1. Place 1 cup of butter in a saucepan over medium heat. Melt and cook, whisking occasionally, until milk solids toast and the butter becomes mahogany-colored and smells nutty. Remove from heat immediately and cool slightly.
2. In a medium bowl, whisk together 2 cups of all-purpose flour, baking powder, salt, and 1 tsp of ground cinnamon.
3. In a separate large bowl, beat eggs and granulated sugar until pale and fluffy.
4. Slowly stream in the cooled brown butter and vanilla extract, mixing until the batter is smooth.
5. Alternately add the dry flour mixture and the whole milk to the batter, stirring until just combined.
6. Gently fold in the diced apples until evenly distributed.
7. Prepare the streusel by combining 0.5 cup flour, brown sugar, 0.5 tsp cinnamon, and cold cubed butter, mixing until crumbly.
8. Pour batter into a 9-inch springform pan, top with the cinnamon streusel, and bake for 45 minutes or until a toothpick comes out clean.
