How to Make 3-2-1 Chocolate Mug Cake {Easy 1 Minute Recipe}
Here are the step-by-step directions for making this incredibly easy 1 minute white mug cake.
Step 1: Prepare the Mixture
Gather ingredients.

Combine cake mixes in a large bowl.

Once your mixture is combined, store in a jar or an air-tight container with a tight lid, or a gallon zipper bag. Store in a cool, dry place without a lot of moisture. (I keep mine in the pantry.) The mixture makes 28 servings.

Step 2: Make a Mug Cake with the Cake Mix
Now you are ready to make your 1 minute individual desserts anytime you want one.

Combine 3 tablespoons of the mug cake mix with 2 tablespoons of water in a microwave-safe mug; stir well. Cook for 1 minute.

You can bake your microwave cake in a coffee mug like we did, or a small microwave-safe bowl or ramekin.

Iโve tried this recipe both with spraying the mug with cooking spray and without. The recipe works both ways. Your cake will rise a bit higher if you donโt use cooking spray, but the mug will be a little harder to clean. We typically use this recipe without spraying the mug and havenโt had problems.
Allow the cake to cool a bit, top with optional toppings and enjoy.
