Mmmm, pumpkin! Transform this fall coffee-house favorite into a cake that can be baked right in your microwave in just two minutes.
To cut down on cleanup, mix the batter in a mug, and then pour half of it into the other mug.
To make your own pumpkin pie spice, mix 3 tablespoons ground cinnamon, 2 teaspoons ground ginger, 2 teaspoons ground nutmeg, 1 1/2 teaspoons allspice and 1 1/2 teaspoons ground cloves. Store in airtight container in pantry for up to several months.
