Making a single serving is a good idea for me because I cannot be left alone with baked goods. If I make a whole coffee cake, chances are I will eat a whole coffee cake. So, one serving, it’s gone, no willpower needed. Ü
Cinnamon Streusel Topping:
2 Tbl flour
1 Tbl brown sugar
1/2 tsp cinnamon
1 Tbl butter, softened
In a small bowl, mix together flour, brown sugar, and cinnamon. Mix in butter with a fork until crumbly. Set aside.
Cake:
1 Tbl butter, softened
2 Tbl sugar
1/2 of 1 beaten egg (approx 2 Tbl)
2 Tbl sour cream
drop vanilla
1/4 cup flour
1/8 tsp baking powder
In a mug, mix butter and sugar. Stir in egg (save the other half an egg for your coffee cake tomorrow!), sour cream, and vanilla. Add flour and baking powder and mix just until combined. Pour streusel topping mixture over cake batter. Microwave for 1 minutes, then at 10 second intervals until done; about 1:20 to 1:30 is about right. Cake will be hot! Stir lightly with a fork to let some heat out and distribute the streusel.
