Make an easy air fryer mug cake in no time using minimal ingredients. This single-serving confetti cake dessert is easy-to-make and delicious! Plus, it’s super kid-friendly!

Key Ingredients
The single-serving size is perfect for an on-the-go snack or late-night dessert, and making it in the air fryer makes clean-up is fast and effortless. Here’s everything you need to get started.
- Butter: Making a cake, even a mug cake, should be balanced. The butter helps the cake be moist but firm enough to maintain its structure without drying out. It also prevents the cake from sticking to the mug.
- Flour: I use all-purpose flour for this recipe, but if you prefer a lighter cake, consider using cake flour.
- Sugar: Sweeten the single-serving treat with white sugar.
- Baking Powder: Baking powder is a leavening agent that reacts to the heat of the oven, creating a chemical reaction that helps the cake rise and gives it a light, airy texture.
- Sprinkles: What is confetti cake without rainbow sprinkles? If you’re not making a confetti cake, leave them out or use other sprinkles.
- Milk: Use milk to combine the ingredients.
- Vanilla Extract: Boost the sweetness with a small amount of vanilla extract.
Additions and Substitutions

Equipment
No need for fancy equipment. Make this quick and easy dessert with ramekins or two small microwave-safe mugs and an air fryer. I use an Instant Pot Vortex Air Fryer.

Frequently Asked Questions

Since air fryers are mini convection ovens, any oven-safe dish should be safe, including glass, ceramic, metal, or silicone.
