S’Mores Mug Cake

s'mores mug cake

Right now it’s -10 degrees in Chicago (aka #Chiberia) and I am fantasizing about sitting in front of a roaring fire. I don’t have a fireplace so my Vornado space heater under my desk will have to do for now! But if I did have a fireplace, I’d surely be popping some corn or making some toasty s’mores. The perfect fuel to keep warm through this bitter, winter night.

Since this fantasy is not going to happen right now, the next best thing is a microwaveable vessel filled with a deliciously-portioned-for-one s’mores mug cake. Recently, I’ve started playing around with mug cake versions of traditional baked goodies. I’ve been surprised how well the microwave can “bake” some individual cakes and brownies – and I think you’ll find this s’mores mug cake will definitely satisfy a craving for chocolate, graham cracker and hot marshmallow.

Find your largest microwaveable mug; I recommend one that can hold at least 16 ounces. Coat it with non-stick spray for easy cleanup, then mix all the ingredients together in the mug just until combined. Zap it on HIGH in your microwave for about 90 seconds and voila! You’ve got a campfire treat courtesy of your microwave.

Pair a s’mores mug cake with a cup of steaming hot cocoa and you’ll be ready to face the polar vortex head on!

S’Mores Mug Cake

Cook Time: 2 minutes

Yield: 1 serving


4 tablespoons all-purpose flour
4 tablespoons brown sugar
1/4 teaspoon baking powder
1 egg
3 tablespoons milk
3 tablespoons vegetable oil
1/3 cup mini marshmallows
1/4 cup milk chocolate chips
2 graham crackers, crushed


Combine all ingredients in a large microwaveable mug (recommend 16 ounce-size). Whisk well until blended.

Microwave on HIGH for 90 seconds, then check to see if it is done. If not, continue to microwave in additional 30-second intervals. Be careful not to overcook or cake will become rubbery.

Let cool down for a bit (the cake will continue to cook in the mug), then enjoy with a spoon!
