Air Fryer Vanilla Mug Cake - A Quick, Cozy Treat for One

Prep Time 5 minutes
Cook Time 7 minutes
Total Time 12 minutes
Servings 1 servings

Ingredients

  • 1/4 cup all-purpose flour (spooned and leveled)
  • 2 tablespoons granulated sugar
  • 1/4 teaspoon baking powder
  • Pinch of fine salt
  • 3 tablespoons milk (dairy or unsweetened almond milk)
  • 1 tablespoon neutral oil (canola, vegetable, or light olive oil)
  • 1/2 tablespoon melted unsalted butter (optional but recommended for flavor)
  • 1 teaspoon pure vanilla extract
  • Optional add-ins: 1 tablespoon mini chocolate chips, a pinch of cinnamon, or 1 teaspoon rainbow sprinkles
  • Optional topping: whipped cream, a dusting of powdered sugar, or a scoop of ice cream

Instructions

  • Choose the right mug: Use a microwave-safe and oven-safe ceramic mug that holds at least 12 ounces. This gives the cake room to rise.
  • Preheat the air fryer: Set it to 330°F (165°C). Preheating helps the cake rise evenly and bake on time.
  • Mix dry ingredients: In the mug, add flour, sugar, baking powder, and a pinch of salt. Stir with a fork until well combined and no streaks remain.
  • Add wet ingredients: Pour in milk, oil, melted butter, and vanilla. Stir until the batter is smooth. Scrape the bottom and sides so no dry pockets hide.
  • Add optional mix-ins: Fold in chocolate chips, sprinkles, or a dash of cinnamon if you like.
  • Air fry: Place the mug carefully in the air fryer basket. Cook at 330°F (165°C) for 8–10 minutes. Start checking at 8 minutes.
  • Check doneness: The top should look set and spring back lightly when touched. A toothpick inserted in the center should come out with a few moist crumbs, not wet batter.
  • Cool briefly: Let the mug cake rest for 2–3 minutes. This sets the crumb and keeps it tender.
  • Finish and serve: Top with a dollop of whipped cream, a dusting of powdered sugar, or ice cream. Enjoy warm.
