Cinnamon Spice Apple Cake! Similar to a coffee cake and perfect for brunch. This cake is packed with fresh apples and spices and topped with cinnamon strusel topping. A must-make for Fall.
Preheat oven to 350 degrees F. I like to spray and line 9x9 with parchment for easier clean up!
Chop the apples and mix with the brown sugar and cinnamon.
Make the buttermilk. Mix together milk and vinegar in a measuring cup. Set aside to let curdle, about 3-4 minutes.
In a large bowl, gently mix together the butter, sugars, yogurt, vanilla, salt, baking powder, soda and flour. Add in the buttermilk at the end. The batter will be thick!
Spoon half of the batter into your prepared pan, then layer in half of the apples with their juices. Spoon on the remaining batter and top with the remaining apples.
Crumble together the brown sugar, flour, cinnamon, and vanilla to form a mixture similar to wet sand. Crumble on top of the cake.
Bake for 45-50 minutes until toothpick comes out clean from the middle. Remove and let cool before slicing.
