I use to make a decent coffee cake and then suddenly after having my son, it was like I could not make one that was even close to edible. Now that I have take up the 'Sourdough Life' (someone please make that as a vinyl to slap on my van), I decided to give one a try and it turned out AMAZING!
1/2 cup butter, softened
1 cup granulated sugar
1 teaspoon vanilla
2 cups all purpose flour
1 tsp baking powder
1 tsp baking soda
1/2 tsp salt
1/2 cup sourdough starter discard
1/2 cup sour cream
Struesel topping ingredients:
1/4 cup cold butter diced
1/4 cup all purpose flour
1/2 cup brown sugar
1 tblsp cinnamon
1 tblsp vanilla powder (optional! Can be found at MarketSpice in Pike Place Market or order online!)
Preheat oven to 350 degrees with the rack in the center. Prepare a 9x9 or 9x11 with non stick cooking spray
Beat the butter and sugar with an electric mixer until combined. Add the eggs and vanilla and beat until fluffy.
Combine dry ingredients for the cake into a mixing bowl.
Add sourdough starter into wet ingredients. Pour dry ingredients in slowly to the wet ingredients slowly until combined. Add in the sour cream and mix until well combined. Batter will look like a heavy cake.
To make the topping, cut the butter into the flour until the size of peas. Stir in brown sugar and cinnamon. If you have problems getting the crumble to mix, don't be afraid to use your hands!
Layer half of the cake batter into the prepared pan. Sprinkle half of the topping on the cake batter. Gently spread the remaining cake batter on top, and top with the rest of the topping.
Bake for 40-45 minutes until a toothpick inserted into the center comes out clean. If the top is browning to fast but the center remains uncooked, place foil over the top loosely to prevent it drying out.
Cool in the pan for at least 15 minutes and then cut into squares and serve!
This recipe was so good that my daughter wanted to have THREE slices (I cut her off after 2), my mom who isn't a coffee cake person enjoyed it, and we all decided this will be a once a month happening and become a tradition!
