Ingredients
-
4 tablespoons gluten-free all-purpose flour
-
2 tablespoons sugar
-
1/4 teaspoon baking powder
-
Pinch of salt
-
3 tablespoons milk (dairy or non-dairy)
-
1 tablespoon vegetable oil or melted butter
-
1/4 teaspoon vanilla extract
-
1 tablespoon rainbow sprinkles (plus extra for topping)

Step-by-Step Instructions
1. Mix Dry Ingredients
In a microwave-safe mug (roughly 12 oz size), whisk together gluten-free flour, sugar, baking powder, and a pinch of salt.
2. Add Wet Ingredients
Add milk, oil (or melted butter), and vanilla extract to the dry ingredients. Stir until a smooth batter forms, making sure there are no lumps.
3. Fold in Sprinkles
Gently fold rainbow sprinkles into the batter, reserving a few to sprinkle on top.
4. Microwave the Mug Cake
Microwave the mug cake on high for 70–90 seconds, depending on your microwave wattage. The cake should rise and appear set on top but still moist. Avoid overcooking, as it can make the cake dry.
5. Serve and Enjoy
Let the mug cake cool for 1–2 minutes before enjoying. Top with extra sprinkles, whipped cream, or frosting if desired. Eat directly from the mug or carefully transfer to a plate.
Tips for the Perfect Gluten-Free Mug Cake
-
Use Gluten-Free Flour Blend: A 1:1 blend with xanthan gum works best.
-
Do Not Overmix: Overmixing can make the cake dense.
-
Adjust Cooking Time: Microwaves vary; check at 60 seconds and continue in 10-second intervals if needed.
-
Use Fresh Sprinkles: Avoid old or wet sprinkles, as they can affect texture.
Flavor Variations
Chocolate Funfetti
Replace 1 tablespoon of flour with cocoa powder and add chocolate chips for a chocolate version.
Vanilla Almond Funfetti
Add ¼ teaspoon almond extract instead of vanilla for a nutty twist.
Fruity Funfetti
Fold in small fresh berries like blueberries or raspberries for a fruity surprise.
Peanut Butter Funfetti
Add 1 teaspoon peanut butter to the batter for a creamy, nutty layer.
Storage and Leftovers
-
Best Enjoyed Fresh: Mug cakes are best eaten immediately, as they can become dense if stored.
-
Reheating: If needed, microwave for 10–15 seconds to warm.
