This innovative recipe combines two classic desserts into one delicious treat. The cake batter is made with a combination of flour, sugar, eggs, and butter, and is infused with apple pie filling for added flavor. The cake is then topped with a layer of streusel, made with brown sugar, flour, and butter, and baked until golden brown. Once the cake is done, it is topped with a drizzle of caramel sauce for added sweetness. This cake is perfect for fall gatherings and is sure to be a crowd-pleaser.
