I first tried this back in fall 2021 when my daughter had friends over and they wanted “something sweet but not a whole cake.” I grabbed four mugs, mixed everything right in them, and popped them in the air fryer.

What You’ll Need
The beauty here is simplicityeverything you need is probably already in your kitchen. You’ll use butter for richness, all-purpose flour and baking powder to give it that fluffy rise, and a touch of granulated white sugar for sweetness. Milk and vanilla extract make it tender and aromatic, while rainbow sprinkles add a pop of color and a little nostalgic fun.
Pro Tip: Melt your butter in the microwave for about 20 seconds, then divide it between your ramekins before you start mixing. It keeps everything from sticking and adds moisture to every bite.
| Ingredient | Purpose | Easy Swap |
|---|---|---|
| Butter | Moisture & richness | Coconut oil or margarine |
| All-purpose flour | Structure | 1:1 gluten-free blend |
| Granulated white sugar | Sweetness | Coconut sugar or honey (slightly less) |
| Milk | Tenderness | Almond, oat, or coconut milk |
| Rainbow sprinkles | Color & fun | Mini chocolate chips or leave plain |
How to Make It
Start by preheating your air fryer to 350℉this helps the cake bake evenly and get that slightly golden top. Divide your melted butter between two ramekins so each one gets a nice base layer that prevents sticking.
In a liquid measuring cup, whisk together the flour, sugar, baking powder, and sprinkles until they’re evenly combined. Then stir in the milk and vanilla extract until you have a smooth batter with no lumps. Pour the batter into your prepared ramekins, filling them about halfway to leave room for rising. Use a paper towel to wipe down any splatter on the sidesthis keeps the edges from getting too dark.
Cook for 6 to 8 minutes, checking with a toothpick at the 6-minute mark. If it comes out clean or with just a few crumbs, you’re done. Let them cool for a minute or two before digging inthey’ll be hot straight out of the air fryer.
Tips for Perfect Results Every Time
After testing this dozens of times with my family, I’ve learned a few tricks that make all the difference. Don’t skip whisking the dry ingredients firstit distributes the baking powder evenly so you don’t get flat spots. And resist the urge to overfill your ramekins; halfway is plenty, or you’ll end up with overflow and uneven cooking.
Note: Every air fryer runs a little differently. If your cakes are browning too fast on top but still wet in the middle, drop the temperature to 330℉ and add a minute or two to the cook time.
Serving and Storage
These little cakes are best enjoyed warm, straight from the ramekin with a spoon. If you want to dress them up, let them cool for a few minutes and top with a dollop of whipped cream, a drizzle of chocolate syrup, or even a spoonful of peanut butter. They’re also delicious with fresh berries on the side.
Store any leftovers covered in the fridge for up to two days. Reheat in the microwave for 15 to 20 seconds to bring back that just-baked warmth.
| Storage Method | Duration | Reheating Tip |
|---|---|---|
| Room temperature (covered) | Same day | Microwave 10-15 seconds |
| Refrigerator | Up to 2 days | Microwave 15-20 seconds |
| Freezer | Not recommended |

FAQs ( Air Fryer Mug Cake )
How long does it take to cook in the air fryer?
This recipe typically takes 8-12 minutes at 350°F. Start checking at 8 minutes by inserting a toothpick in the center. If it comes out clean or with just a few moist crumbs, it’s done. Cooking time may vary slightly depending on your air fryer model.
What size mug works best?
Use a microwave-safe ceramic mug that holds 12-16 ounces for best results. The mug should be wide enough to allow proper air circulation and deep enough to prevent overflow. Avoid metal mugs or very thin ceramic that might crack under high heat.
Can I make multiple servings at once?
Yes, you can cook 2-3 mugs simultaneously if your air fryer basket is large enough. Make sure there’s at least 1 inch of space between each mug for proper air circulation. You may need to add 1-2 extra minutes to the total cooking time.
Why is my cake dry or rubbery?
Overcooking is usually the culprit for dry, rubbery texture. Reduce cooking time by 1-2 minutes next time. Also check that you’re measuring ingredients accurately – too much flour or not enough liquid can create a dense result. Don’t overmix the batter either.
Can I add frosting or toppings?
Absolutely! Let the cake cool for 2-3 minutes before adding toppings. Cream cheese frosting, whipped cream, fresh berries, or a simple powdered sugar glaze all work wonderfully. Add chocolate chips or nuts to the batter before cooking for extra flavor.
