Preheat oven to 375°F. Lightly coat an 8-by-8-inch baking dish with cooking spray. Stir together flour, sugar, cocoa, baking powder and salt in a large bowl. Combine milk, egg, oil and vanilla in a glass measuring cup. Make a well in center of the dry ingredients and gradually pour in the milk mixture, stirring until combined. Spoon into the prepared pan and spread evenly. Dissolve brown sugar in coffee; spoon over batter. (I missed this step.) Bake until a toothpick inserted in center comes out clean, about 25 minutes. Let stand for 10 minutes; serve hot or warm. (It took 35 minutes for this to work for me.) This recipe is originally from Eating Well.
Notes
My opinion:
The cake is so so much better warm! It’s not bad. It does need a little something though. It tastes a bit off, but not in a bad way. That might be my fault as I used the good unsweetened cocoa. I would definitely make this again as it was super simple and made the house smell wonderful. Next time though, I will add chocolate chips or peanut butter chips or a raspberry glaze.
