This is a great summer dessert recipe. If you’re craving brownies but don’t want to heat up the kitchen in summer, the Instant Pot pressure cooker is perfect.
I make these Instant Pot brownies using the pot-in-pot (PIP) method. It’s a convenient Instant Pot technique that involves adding water to the Instant Pot and cooking your dish in a separate oven-safe container(s) placed on a trivet.
This technique works so well because the Instant Pot requires steam to cook, and we don’t want to add liquid to the brownie batter.
PIP is especially great for pressure cooker desserts like cheesecakes, lava cakes, custards, and for dishes like lasagna or casseroles.
This recipe is also a great option when you’re looking for an Instant Pot dessert for two!
Ingredients and Tips
🧂 Ingredients Needed for Making Instant Pot Brownies in a Jar
💡 Ingredient and Recipe Tips
🫙 Mason Jars: Use 7 tall half-pint mason jars filled to half-height for these Instant Pot brownies. This portion is perfect with ice cream on top. Want larger servings? Fill jars more and cook for a bit longer.
🍫 Creme de Menthe: The recipe includes Andes creme de menthe chocolate mint candies. Mint lovers will be in heaven! Not a mint fan? Substitute with chocolate chips or omit altogether.
︻ Trivet: A trivet is essential for elevating the mason jars and easily removing them. I use the handled trivet that comes with the Instant Pot.
💧 Condensation: Cover jars lightly with aluminum foil to prevent water droplets from falling into your brownies. Be careful when removing the foil to avoid steam burns.
⃝ Sealing Ring: Consider getting a second sealing ring specifically for desserts. My original ring retains savory food odors despite cleaning attempts. Color-coded sealing rings are perfect for keeping track of which is for savory dishes and which is for desserts, oatmeal, and other non-savory foods.

Julie McCulloch says
I’m a diabetic and have substitutions for everything except for the chocolate. In some keto recipes I’ve seen cocoa powder used intsead of chocolate. If I wanted to sub the cocoa powder, do you have any advice on what i might need to add or increase to compensate? I’m new to IP’s and baking in general, so I’m really clueless. TIA.
Paint the Kitchen Red says
Julie, I’ve not tried it but I have read that to replace each ounce of unsweetened chocolate, use 3 tablespoons cocoa powder plus 1 tablespoon butter. Hope that helps!
Sarah says
Could I use semi-sweet choclate chips in place of the bittersweet chocolate? I have those on hand 🙂
Paint the Kitchen Red says
Sarah – did you end up trying it out. Sorry, I was camping this weekend and had no wifi to answer your question! I haven’t tried chocolate chips, but I think they would work if they are the same weight.
Debbie says
Would it work to put in 4 pint sized jars for 20 min? I have big boys to feed.
Paint the Kitchen Red says
Debbie, just to let you know – they’re pretty rich! That’s a great question, and I’m not sure about the answer. I think since the jars will be wider, you might need to increase the pressure cooking time by a few minutes. Maybe cook for 20 minutes, quick release and check the doneness and if needed, pressure cook on ‘manual’ mode for another 3 minutes. Let me know how it works for you and thanks for your comment.

I loved these mint brownies. I made them is custard cups and they turned out great – we ate them plain, without ice cream while they were still warm!
