Irish Cream Coffee Cake is the breakfast or brunch treat you need for St. Patrick's Day! The tender cake is spiked with Irish cream, and topped with a brown sugar crumble.
Pour 1/2 of the batter in a prepared square baking pan. Top evenly with 1/2 of crumble topping. Then spread on remaining cake batter, and top with the rest of the streusel crumble.
Bake for 40 minutes, and cool the pan for 15 minutes on a wire rack.
