This is the easiest peanut butter and chocolate bundt cake you will ever make. It tastes like you spent hours making it too. Like all peanut butter recipes, I make this one was for my sweet and awesome husband. He’s the coolest guy around and he loves peanut butter and chocolate. It’s his favorite dessert combo for sure! I like to make him happy but I’m also a total cheat when I do it.

I made this cake a couple of months ago and I didn’t post it right away because I planned on remaking it and taking more pictures to share with you. I’ve actually made it again since then, but it was eaten too quick to get pictures.

This is so easy to make that it’s perfect for a busy weeknight. The only problem when I made it on one of my busy weeknights is that was too dark for pictures. I thought that Id just take some pictures of the leftovers the next day when the lighting was better… too bad there were no leftovers!

How to make the Bundt Cake:

Grab your favorite cake mix or homemade recipe. Pour it into your bundt pan.

Using the most natural peanut butter you can find, pour 1/2 of a jar into the top of the batter. Swirl it a little. You can use a small jar or a large one. Just depends on how much peanut butter you like. The peanut butter is so important in this recipe. I’m sure that any ole peanut butter would work so if that’s what you’ve got in your pantry totally use it. The natural one works best in this recipe because of it’s high oil content and lack of fillers or stabilizers. Have you noticed how some of the more processed peanut butters tend to not separate, as in the peanut butter and the oil stays mixed and thick? Natural ones that are just peanuts and sometimes a sprinkle of salt tend to separate and are a bit thinner. It’s really not a big deal to have to stir your peanut butter right? In this recipe, it is used to our advantage because the thinness of the peanut butter is perfect to get a nice swirl and to distribute the flavor!

If you think the cake part was easy you will love this part. The frosting. Who doesn’t love frosting? I asked my three-year-old if she likes cake and she said she loves cake because that means she can eat frosting. This kid is strange I tell you. She will take a piece of cake and get every last drop of frosting off the slice and then turn around and offer everyone the naked cake slice with lick marks on it.  Actually, now that I write it out, maybe she’s on to something.

Back to the frosting. You will need a container of pre-made vanilla frosting and the rest of your peanut butter. Empty the frosting into a microwave safe bowl and heat till it’s almost liquid. Then quickly stir the peanut butter into the frosting. Quickly pour the frosting onto the cake. It is divine!

  • Favorite way to eat peanut butter? Straight 🙂 But I love PB and chocolate combos. Yuum!

    • Truth be told I rarely get to cook with peanut butter because I have so many people in my home that eat it out of the jar 🙂

      • My hubby is going to love this. The frosting looks out-of-this-world !! You have some of the best and most divine recipes I’ve come across yet. A gold mine I can’t wait to share with my friends. Thank you so much for sharing. Oh, and my mom used to make homemade fudge and pour it on a cake…….it was my birthday favorite. And when the fudge was gone the cake was, well, useless. Especially when it was a white cake 🙂 🙂 chocolate chip cookie dough cake omg. Thanks again, Diana Burke, Bonney Lake, WA.

  • Chocolate and peanutbutter is a superb combination. You have a lucky husband.

  • Your cake looks amazing, I love the look of that frosting!
