Why You’ll Love This Recipe

You don’t have to turn the oven on.
Perfect for small celebrations. It makes 5 to 6 servings.
Bakes faster in the air fryer than in the oven. The air frying time is only 22 to 24 minutes.
Moist texture. Because the cake cooks so fast, it doesn’t dry out.
Super creamy frosting. A thick layer of rich buttercream frosting finishes the cake off.
Loaded with colorful sprinkles. I just love sprinkles. Don’t you?

Small Cake Pan

You’ll need a small 7-inch cake pan for this recipe. One that has at least 2-inch sides is perfect. I use this Aluminum Round Cake Pan.

(More detailed instructions in recipe card below.)

Mix dry ingredients. In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
Cream butter and sugar. Using an electric mixer (either hand-held or stand) beat softened butter and sugar until creamy.
Mix in the eggs, sour cream, and vanilla extract.
Add flour alternating with milk and mix just until combined.
Stir in the sprinkles.
Transfer to a greased cake pan. Air fry 22 to 24 minutes at 320 degrees.
Let cool and then frost. To make frosting, beat butter until creamy and then beat in powdered sugar, heavy cream, and vanilla extract. Stir in sprinkles.

Do NOT overbeat the batter.
Air fryer cooking times vary so check early and check often.
If the top starts to get too brown before the center is set, cover loosely with aluminum foil.
Cake is done when a toothpick inserted in the middle comes out clean or with just a few crumbs attached.
Cool cake completely before frosting.

Store at room temperature in an airtight container for 2 to 3 days at room temperature or in the refrigerator for 4 to 5 days.
