Air Fryer Coffee Cake

This recipe is from forktospoon.com

I accidentally started adding ingredients to my bowl without opening the post so I ended up making 1 1/2 of these...oops!

Cake-1/2c melted butter 3/4c sugar 1t vanilla 1 egg 2c flour 

  2t baking powder 3/4c milk

Topping-1/4c melted butter 2/3c sugar 1/4c flour 2t cinnamon

Spray pan - 325 25 minutes - check w/toothpick

I can fit an 8x8 pan in my air fryer

If you can only fit a 6" pan, I'd probably cut this recipe in half

or cook it in two batches so it's not so thick the center won't cook
