Line a 6-inch pan with parchment paper and butter the parchment and the side of the pan. Set aside.
In a large mixing bowl, with a hand mixer, mix eggs, butter, and sugar until all ingredients are combined and creamy, about 2 minutes
Add cream, oil, and vanilla extract. Mix until all incorporated. You will have a smooth texture
In a separate bowl, whisk together flour, baking powder, and salt. Add the sprinkles to the flour and mix until all sprinkles are coated.
Slowly add the flour mixture to the egg mixture. Mix until all incorporated, and you don't see any more dry flour, but do not over mix. I prefer to use a whisk or large spatula for this step so I don’t overmix.
Pour half the mixture into a prepared 6-inch cake pan, and keep the remaining in the fridge
Cook in the air fryer on manual at 320℉ for 15 to 18 minutes or until the cake is nice and golden. A good check to know the cake is done is to insert a toothpick. If it comes out clean the cake is done.
Cool off for a few minutes in the air fryer basket, then transfer the pan to a cooling rack. Remove the cake from the pan and pull the parchment paper off.
Cook your remaining batter as above.
Let the cake cool completely before icing.
Use your favorite vanilla buttercream to ice the cake once it is completely cooled.
Serve and Enjoy!
Notes
This batter makes enough for 2 cakes in a 6-inch pan. I only have one pan, but if you have 2 you can prepare both and keep the second one in the fridge until ready to bake.
I would not suggest cooking both at the same time. I have noticed they bake more evenly when doing one at a time.
