Overview of making the Coffee Cake
To make the cake:
- Sift the dry ingredients: In a large bowl, combine flour, baking powder and pinch of salt in a bowl. Set aside.
- Beat the wet ingredients: On medium speed, beat vegetable oil, sugar and eggs until combined and smooth. Add the sour cream and milk. Beat on medium – low speed until just combined.
- Add the dry ingredients: Add the flour mixture and beat until just combined. Do not over mix. The cake batter will be very thick.
To make the cinnamon brown sugar filling:
- Melt the butter. Then stir in cinnamon, flour, and brown sugar. Mix until mixture resembles small crumbs.
To make the oatmeal streusel topping:
- Melt the butter. Then stir in cinnamon, flour, brown sugar and old fashioned rolled oats. Mix until mixture resembles small crumbs.
Assembly:
Grease 8×8 inch pan. Pour half of the batter into prepared pan. Spread with a spoon. Sprinkle the cinnamon brown sugar filling over the batter. Carefully spread the remaining batter over the filling. Sprinkle with the oatmeal streusel topping.
Bake for 35-40 minutes. Or until streusel topping is golden brown and inserted toothpick comes out clean.
To make the glaze:
Add powdered sugar, milk and coffee into a small bowl. Stir until smooth. Add more milk, or powdered sugar until desired consistency. Drizzle the top of the cake with the glaze.
Tips
- Do not over mix the batter when adding the flour. Beat until the flour is just incorporated and smooth.
- The cake batter will be VERY thick. Spread the batter evenly into the pan to ensure even baking. If you have trouble spreading the batter, spray the back of the spoon with cooking spray or brush a little bit of melted butter. This will ensure the batter does not stick to the spoon.
- Measure flour correctly. Spoon the flour into a cup then level with a butter knife. This ensures that your have the right amount of flour and the flour is not packed.
- When making the glaze, adjust the powdered sugar and milk to the consistency of your liking. If you like a thicker glaze add more powdered sugar. To thin out the glaze add more milk. Adjust the coffee flavor to your liking as well.
This cake tastes best when it’s warm! Reheat the cake before serving.
Store the coffee cake in an air tight container or covered with plastic wrap or aluminum foil, on the counter for 1-2 days and in the refrigerator for up to a week.
ENJOY!
