The recipe was posted on Pinterest. I also shared it on my blog, but it's been a while. I've also made a couple of additions. I tend to heap all the measurements, except the water.
3 Tablespoons of white cake mix
1/2 teaspoon of pumpkin pie spice. I make my own.
1 Tablespoon pumpkin puree
1 Tablespoon of water
I also add:
1/2 Tablespoon of chopped semi-sweet chocolate chips
1/2 Tablespoon shredded coconut
Blend and cook in microwave for 60 seconds
I should take a picture of the cake, but I haven't yet, so these are clouds I thought were interesting.
