Can You Cook Cake In The Instant Pot

Cooking cake in the Instant Pot can be done. Instead of a traditional oven, you will more “steam” your cake. It will change the texture of a cake and make it more fudge-like in texture and a bit denser.

I used my 7-inch cake pan for my Instant Pot. Then you wrap in aluminum foil to prevent liquid from getting in cake! This Instant Pot Chocolate Zucchini Cake recipe is so easy and I think you will love it.

Why Do You Strain And Squeeze Zucchini

Zucchini holds a lot of water inside. It is very important as you shred your zucchini you then lightly sprinkle with salt and then place in a strainer.

That way the excess liquid can drip off the zucchini. Then one last step is using a cheesecloth or even a paper towel to squeeze out any excess liquid.

For the 1 cup of zucchini, I shredded I pulled off probably 1/2 cup of liquid once It was all done.

If you don’t get the liquid removed your cake will be soggy and it won’t cook properly.

How To Store

You will need to store your cake in the fridge. It is best to do this as it can go bad if left on the counter.

The cake will store for around 3-4 days. This cake will dry out with each day so it is best when eaten fresh.

Can You Freeze This Cake

Absolutely! You are more than welcome to wrap up in aluminum foil and then place in freezer bag or airtight container.

Store for up to three months. Then thaw in the fridge overnight or on the counter for a quick thaw. I like to pre-slice it so when I get a craving I pull just one slice out of the freezer.

Instant Pot Chocolate Zucchini Cake

Yield: 1 cake
Prep Time: 10 minutes
Cook Time: 50 minutes
Additional Time: 20 minutes
Total Time: 1 hour 20 minutes

Instant Pot Chocolate Zucchini Cake is a double chocolate zucchini cake. This is the best Instant Pot zucchini recipe I have made by far. Moist, fudgy, and loaded with sweet chocolate morsels in every bite.


  • 1 cup + 2 tablespoons all-purpose flour
  • 1/2 cup cocoa powder
  • 1 cup brown sugar
  • 1 teaspoon salt, divided
  • 1 teaspoon baking soda
  • 1/4 cup vegetable or canola oil
  • 1/4 cup butter, melted
  • 1/2 cup sour cream, full fat
  • 2 large eggs + 1 egg yolk, room temperature
  • 1 cup shredded zucchini
  • 1/2 teaspoon vanilla extract
  • 3/4 cup chocolate chips milk chocolate or semi-sweet


  • 1/2 cup powdered sugar
  • 1 tablespoon milk


  1. The first thing you want to do is shred your zucchini and then place it in a strainer. Sprinkle with 1/2 a teaspoon of salt and let sit. Every now and again go and press it down to try and get the liquid to strain from zucchini.
  2. Now in a bowl, you want to add your brown sugar, oil, melted butter, and give a good mix.
  3. Then toss in your sour cream, eggs, and vanilla. Mix again.
  4. Once creamy, stir in your cocoa powder and whip it up.
  5. Once incorporated you will add in all your flour, baking soda, and the other 1/2 teaspoon of salt.
  6. Now grab your zucchini and place it in a cheesecloth or paper towel and squeeze it hard to release any more liquid.
  7. Pour zucchini and chocolate chips in the bowl, and whip it up.
  8. Now pour your cake batter into a parchment-lined 7-inch pan and then wrap tightly with aluminum foil. Make sure the center is up a bit or the cake will stick to the top of the aluminum foil as it rises.
  9. Pour 1 1/2 cup of water in Instant Pot, and then place a trivet or a silicone sling with cake sitting on top.
  10. Place Instant Pot lid and ensure the vent is sealed. Do high pressure for 50 minutes, with a natural release of 20 minutes.
  11. Remove any extra pressure off after 20 minutes. Remove cake and allow to cool on a cooling rack.
  12. Once the cake is cool whisk powdered sugar and milk together and then drizzle over your chocolate zucchini cake.


Make sure to stick a toothpick in your cake to ensure it comes out clean. If not you can return the cake and cook for another 5-10 minutes.

This is a pretty rich cake, so feel free to do 1/2 cup of chocolate chips if you would prefer less rich.
