3 Ingredient Funfetti Cake Mix Mug Cake Ingredients & Tested Substitutions

• Gluten Free Funfetti Cake Mix. I like this gluten free funfetti cake mix, but you can use your favorite funfetti cake mix or gluten free vanilla cake mix.

• Applesauce. Applesauce works best here as an egg replacer however you can substitute this for pumpkin puree or ripe bananas if that's all you have on hand. Note that it will change the color and the flavor a little bit.

• Milk. My preference is to use almond milk but you may use oat milk, soy milk or whatever type of milk you prefer.

• Vanilla Frosting. Frosting is optional but I like to use Miss Jones Frosting because it is gluten free and vegan & the ingredient list is cleaner, however you may use whatever type of frosting you prefer.

• Rainbow Sprinkles. The Miss Jones Frosting Mix comes with funfetti sprinkles, but if you'd like to get your own I like to opt for natural, dye free sprinkles. Also optional, but fun to add!

3-Ingredient Mug Cake Step-By-Step Instructions

1. Mix the cake batter. Lightly grease a microwave safe coffee mug with olive oil or your favorite cooking spray. Add the box cake mix, applesauce and milk to the mug and mix well using a fork or small whisk until you achieve a smooth batter and no clumps of dry ingredients remain.

2. Microwave. Place the mug in the microwave & heat for 60 seconds. After 60 seconds, check for doneness using a toothpick inserted into the center of the mug cake. If it is not fully cooked, an easy way to avoid over cooking the cake is to reheat it in 5 second increments.

3. Add toppings. Add toppings like frosting & sprinkles if using & enjoy!

Expert Tips & Tricks

• Cooking time may vary depending on the strength of your microwave. If the mug cake is not fully cooked after 60 seconds, reheat it in the microwave in 5 second increments to ensure you end up with a mug cake that has a moist texture and it does not become rubbery.

• If you do not have a microwave-safe mug you can use a small ramekin instead.

• Top the microwave mug cake with vanilla frosting & sprinkles or add a scoop of vanilla ice cream for a truly decadent dessert!

• Instead of using funfetti cake mix, use vanilla cake mix and top the mug cake with delicious toppings like caramel sauce, raspberry jam, fresh berries, or natural peanut butter.

• Add 1-2 tablespoons of your favorite protein powder for a little extra protein boost.
