Can you believe that you can make a cake in the Instant Pot pressure cooker? I KNOW.

It took a few rounds of testing to get it just right, but this Instant Pot Spice Cake is a winner! I did have to buy a special cake pan with a removable bottom just for this recipe, but I’ve already made a few different versions of my Instant Pot cake, so it was worth it.

I fully admit that the texture isn’t exactly the same as a traditional cake, it’s not nearly as fluffy. The texture of an Instant Pot cake is more of a flourless cake, much more dense and moist, but totally yummy!


I kept this recipe super simple, using buckwheat flour, pumpkin puree, almond milk, vanilla extract, pumpkin pie spice, melted ghee (use coconut oil to keep it vegan), and maple syrup to give it a holiday flavor.

Recipe Steps

The steps to making an Instant Pot cake are similar to those of making a regular cake you would bake in the oven, with a few exceptions.

  1. You’ll need a couple of long (15 inches at least) foil that you will fold to make “handles” for your cake pan. This will allow you to manage the cake pan easier when you’re taking it in and out of the Instant Pot.
  2. As with making a regular cake, you just combine and stir together your wet and dry ingredients, and pour the patter into a lightly-greased cake pan.
  3. You only need 15 minutes cooking time in the Instant Pot at high pressure to bake your special little cake.
  4. Let the temperature come down naturally after the cooking time is complete, and then remove the cake!
  5. The cake will need to cool some more after removing it from the Instant Pot before you can cut it. Then, when it’s at or around room temperature, it’s ready to eat.

I described how I made the aluminum handles above, but this is what they look like.

The handles just make it so much easier to get the pan out of the Instant Pot. I used my 6-quart Instant Pot, and it was a perfect fit!

The final result turned out so great, and I hope you love this recipe as much as I loved testing (and eating) it.
