This quick breakfast cake, with buttery cinnamon streusel sinking into the top, has been a holiday and vacation favorite in our family for years. Check out my Banana Chocolate Chip Streusel Cake for a delicious variation. Recipe makes a 9" square pan, and may be doubled for a 9" X 13" pan.
Grease and flour 9" square baking pan. Preheat oven to 350 degrees F. Combine streusel ingredients thoroughly in a small bowl, set aside.
Cream together sugar and butter in a large mixing bowl.
Beat in egg.
Stir in milk.
Sift together dry ingredients, add to mixing bowl. Stir until just combined.
Spread batter in pan, and sprinkle streusel over top. As you are sprinkling, squeeze some streusel together into pebble-sized chunks, and drop them over cake batter.
Bake at 350 degrees F for 25 to 35 minutes, until batter is golden brown and center springs back when touched lightly.
