Ingredients

Instructions
This section gives an overview of the steps. Complete instructions appear in the recipe card below.

- Label a gallon-size zip-top bag with the mix name and the simple 3-2-1 directions.
- Combine one package of flavored cake mix and one box of angel food cake mix in the bag. Seal and shake until fully blended.

- To bake, use a microwave-safe mug or paper cup. If using a reusable mug, lightly coat the inside with non-stick spray for easier cleanup.
- Add 3 tablespoons of the mug cake mix and 2 tablespoons of water to the mug. Stir to combine.
- Fold in 1 tablespoon of add-ins such as chocolate chips, jam, or syrup for extra flavor and moisture.

- Microwave on high for about 1 minute. Microwave wattage varies, so watch the cake closely to avoid overcooking.
- Let the mug cake cool for a few minutes before adding frosting or sprinkles.
Mug cake tips
- Mix any flavored cake mix with angel food cake mix. Chocolate and vanilla are versatile, but flavors like red velvet or strawberry also work well.
- Add-ins boost flavor and moisture. Try chocolate chips, peanut butter chips, mini marshmallows, jam, or syrup.
- For care packages, include disposable paper cups and measuring spoons. Aerosol nonstick spray is not allowed in many airmail shipments, so avoid sending it.
- Using nonstick spray when baking in reusable mugs makes cleanup much easier.
- Fill mugs no more than half full to prevent overflow. An 8-ounce cup is the minimum size for this recipe; larger add-ins require a larger mug.
- If your microwave mug cake turns out spongy, add moisture before cooking — one tablespoon of syrup, jam, or condensed milk helps greatly.
- To intensify chocolate flavor, add a tablespoon of chocolate syrup or a tablespoon of cocoa powder plus an extra teaspoon of water.
- Because microwaves differ, watch the first cake closely to determine the optimal cook time for your appliance.
- Mug cakes are intended to be eaten right away and are not designed for storage or later consumption.
