S'More Mug Cake Recipe

Serving Size = 2


3 tablespoons graham cracker crumbs, plus more for topping
3 tablespoons butter, divided
¼ cup plus 3 tablespoons milk chocolate chips, divided
2 tablespoons sugar
1 egg yolk
2 tablespoons milk
½ teaspoon Happy Home® Imitation Vanilla Flavor®
5 tablespoons self-rising flour
1 tablespoons cocoa powder
Pinch of salt
10 to 12 mini marshmallows

Mini marshmallows
Milk chocolate chips
Graham cracker crumbs


  1. Lightly grease two 12-ounce microwave-safe mugs. Add ½ tablespoon butter to each mug and microwave for a few seconds until butter is just melted. Divide graham cracker crumbs between the mugs, stir together with butter and set aside.
  2. In a 2-cup microwave-safe measuring cup or bowl, microwave remaining 2 tablespoons butter and ¼ cup chocolate chips until just melted, about 20 to 25 seconds, and stir together. Add sugar and stir. If mixture is hot, allow it to cool before adding egg yolk. Beat in egg yolk with a fork. Stir in milk and Happy Home® Imitation Vanilla Flavor®. Add flour, cocoa, salt and remaining 3 tablespoons chocolate chips and stir until batter is smooth.
  3. Add a tablespoon of batter to each mug then add 5 or 6 marshmallows to each mug. Add remaining batter evenly between two mugs, filling them no more than halfway. Microwave one mug at a time for about 60 to 70 seconds, or about 10 to 15 seconds after cake has risen and peaked. Cake will fall and may appear wet, but should spring back to touch. If not done, microwave 10 to 15 seconds longer and check. Do not over cook or cake will become tough and spongy. Allow to cool slightly and set up. Cake is best when enjoyed shortly after it's prepared.

For Topping: (optional)

  1. Top with marshmallows and chocolate chips and microwave for a few seconds to soften marshmallows. Alternatively, use a torch or broiler to brown and melt topping. Garnish with graham cracker crumbs, if desired.

Recipe Notes:

* Times suggested in recipe are for a 650-watt microwave oven. More powerful microwaves will require less cooking time.
* Recipe was created using a large egg. Using a smaller egg is OK, but avoid using extra large eggs.
