My daughter used this recipe as her first solo baking project for school. The batter prior to adding the coffee was very dense. She added the brewed coffee, hot (because the recipe did not say cold and it said brewed). The mix immediately became the consistency of a cake mix. So she put it in a 9" x 13" pan that was greased and floured, and baked it for 25 minutes. It came out fine. However, the flavor is very mild. (Not to my liking).
