What you will need
This recipe uses 5 simple ingredients that you can find at any grocery store:
- 3 sheets graham crackers crushed
- 3 tablespoons chocolate cake mix
- 2 tablespoons milk
- 1 tablespoon vegetable oil
- 6 pieces mini marshmallows
Step by step instructions
Step 1: Add Graham Cracker Base
Crush graham crackers and press half of them into the bottom of a large microwave-safe mug to create a firm base layer for the mug cake.
Step 2: Mix and Add Cake Batter
In a small bowl stir together chocolate cake mix, milk, and vegetable oil until smooth then pour the batter over the graham cracker layer in the mug.
Step 3: Top with Remaining Crackers
Sprinkle remaining crushed graham crackers over the batter then press mini marshmallows into the top of the batter so they are visible.
Step 4: Microwave and Serve
Microwave on high for 90 seconds until the cake is set and marshmallows are puffed and golden on top. Eat immediately while the chocolate is still melty and marshmallows are gooey.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- chocolate cake mix → 4 tablespoons flour plus 2 tablespoons cocoa powder and a pinch of baking powder if you have no cake mix
- mini marshmallows → marshmallow fluff spread on top after microwaving for an equally gooey result
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Packing the graham cracker base too tightly which prevents the cake batter from cooking evenly throughout
- Adding too many marshmallows which causes them to overflow and bubble out of the mug during microwaving
