Can I bake in my instant pot?

No, technically, an instant pot does not “bake”. It pressure cooks your foods. However, the instant pot is wonderful at making moist and dense baked goods. We love making brownies, boxed cake mix, banana bread, cornbread, and even banana bread in jars right in our instant pot!

What pans can go in instant pot?

You can use glass, ceramic, metal, and silicone pans in your instant pot! Our favorites for making cakes and brownies in our instant pot are the Fat Daddio cake pan and Fat Daddio cheesecake pan. We have also used a Pyrex dish with success!

  • In a medium bowl, mix together flour, cocoa powder, baking powder, and salt. 
  • Slowly mix dry ingredients into wet ingredients.

Notes

It's important to make sure the butter is very soft when mixing up the frosting. If your butter is cold, heat it up in the microwave in 5-10 second increments until soft.

  1. Was wondering how you made a foil sling . Just picked up your book on instant pot recipes and came across that Frase

    1. Hi Lisa! Check page 8 in the cookbook. It explains it. You can also go to my instant pot banana bread recipe for an explanation with pictures: https://aileencooks.com/instant-pot-banana-bread/. Please note that if your trivet has long enough arms to allow you to life the pan from the sides – you will not need a foil sling. It depends on the model of your pressure cooker. Happy cooking! – Aileen
