Instructions
Bring the apples, 3/4 cup sugar, lemon juice and cinnamon to a boil in a small saucepan. Lower the heat and simmer until thickened and apples are very soft, 15-20 minutes. Remove from heat. Mixture will thicken as it cools.
Preheat oven to 350 degrees. In a large bowl or stand mixer fitted with a paddle attachment, beat the butter and sugar together until fluffy. Blend in the eggs, sour cream and vanilla.
In a separate medium bowl, combine the dry ingredients: flour, baking powder, baking soda and salt. With the mixer on low speed, blend the flour mixture into the wet ingredients until combined. Pour into a greased 9x13 baking dish. Drop spoonfuls of the apple mixture onto the cake batter. Using a knife, swirl the apple mixture evenly into the cake batter.
In a small bowl, use a fork to mix all of the topping ingredients together until crumbly. Sprinkle evenly over the cake layer. Bake 40 minutes.
