What’s not to love about the combo of peanut butter and chocolate?
It really is such a delicious pairing–a match made in heaven!
I’m a diehard chocolate fan, but the addition of peanut butter really takes it up a notch!
Since I’ve made several Instant Pot cake recipes, I wanted to make a cake that would include both chocolate and peanut butter, since it’s such a tasty duo!
I have a slew of peanut butter chocolate recipes that served as inspiration, including my peanut butter chocolate banana bread, peanut butter chocolate ice cream, old-fashioned peanut butter cake with chocolate frosting, healthier chocolate peanut butter muffins, and peanut butter chocolate chip cookies.
That’s how this delicious peanut butter chocolate bundt cake recipe came to be!

Why You’ll Love this Peanut Butter Chocolate Cake
Perhaps one of the best things about this cake is that it starts with a doctored-up cake mix, so it’s super easy and practically foolproof!
It’s a swirl of peanut butter cake and chocolate cake, so it has a pretty marbled design throughout.
And can we just talk about the chocolate glaze for a minute? {swoon} It’s just the right amount of sweetness drizzled over the cake!

How to Make Chocolate Peanut Butter Cake in the Instant Pot with a Cake Mix
Making a bundt cake in the Instant Pot is actually really easy, so it doesn’t take much effort to enjoy a delicious dessert! It’s perfect for those of us who have kids hanging from our ankles most of the day!

Ingredients You’ll Need for the Peanut Butter Batter:
- 1 3/4 cups yellow cake mix
- 2 Tbsp vegetable oil
- 5 Tbsp water
- 1/4 cup creamy peanut butter
- 1 egg
Ingredients You’ll Need for the Chocolate Batter:
- 1 3/4 cups devil’s food cake mix
- 2 Tbsp vegetable oil
- 2 Tbsp water
- 1 egg
Ingredients You’ll Need for the Chocolate Glaze:
- 1/2 cup semisweet chocolate chips
- 4 Tbsp butter
- 1 Tbsp peanut butter
- 1 Tbsp corn syrup
How to Make the Cake:
(Full printable recipe is available below)
Prep the Pan. First, use cooking spray to grease a 6-cup bundt pan that fits in your Instant Pot. Pour 1 1/2 cups of water into the insert pot of your Instant Pot and put the trivet in place.
Mix the Batter. Next, you’ll beat together the ingredients for the peanut butter batter in one bowl.

Then you’ll beat together the ingredients for the chocolate batter in another bowl.

To beat each one, beat on low speed for 30 seconds, then increase speed to medium-high and beat for two minutes.
Layer the Batter. You’ll alternate scooping the batter into the prepared pan, then use a knife to swirl the batter a bit.

Pressure Cook. Cover the bundt pan tightly with foil, then use a foil sling or silicone sling to lower the pan onto the trivet. Cook at high pressure for 26 minutes. Allow a full natural release of pressure. Remove the cake pan, cool slightly and invert the cake onto a plate to cool completely.
Prepare the Glaze. In a small glass bowl over a pan of simmering water (a double boiler), melt the glaze ingredients together, stirring often. Be careful not to let it get too hot or the chocolate will seize up!
Once the glaze is smooth, drizzle over the cooled cake. Then serve and enjoy!

Notes and Adaptations:
- I used this aluminum bundt pan. If you are using a dark nonstick bundt pan, you will likely need to increase the cook time by a few minutes.
- If you have some Reese’s cups on hand, you could chop some up and sprinkle on top!

Recommended Equipment:
- Bundt Pan that fits in the Instant Pot
- Trivet (I use the one that came with the Instant Pot)
- Silicone sling or foil sling
