Peanut Butter Banana Bundt Cake with Reese’s Peanut Butter Cups

Halloween is over and most of us are probably still loaded with candy. We had a decent amount of trick or treaters, but we still ended up with leftover candy. Someday I will learn to not buy so much:) I was digging through our bowl of candy to see what was left and pulled out all of the Reese’s Peanut Butter Cups. There were enough leftover to do a little baking. I decided to make a Peanut Butter Banana Bundt Cake with Reese’s Peanut Butter Cups. I love peanut butter and banana together. I’ve made ice cream, cookies, so why not a cake?

I used Dorie Greenspan’s Classic Banana Bundt Cake recipe, from Baking From My Home to Yours, as the base-I love this cake. It is simple to make and a great way to use up your brown bananas. The banana flavor isn’t overpowering, which makes it perfect for playing around with.

I jazzed up the banana cake by adding chopped up Reese’s Peanut Butter Cups.  I also swirled in peanut butter into the cake batter before putting the cake into the oven. Our house smelled like peanut butter, bananas, and chocolate. It doesn’t get much better than that. When the cake was cool, I added a thick and creamy peanut butter glaze to the top of the cake. The glaze alone is amazing. I would have been perfectly content sitting down with a bowl of the glaze and a spoon:) Don’t worry, I didn’t let the cake go to waste, I cut myself a piece and enjoyed every single bite.

The cake is tender, moist, and full of flavor. Each bite is bursting with peanut butter banana goodness. And just when you think the cake can’t get any better, you get a chunk of Reese’s Peanut Butter Cup. Pure bliss! I sure hope you have some Reese’s Peanut Butter Cups leftover from Halloween because you really need to make this Peanut Butter Banana Bundt Cake with Reese’s Peanut Butter Cups. It is calling your name, trust me, I can hear it:)

We’ve gotten lots of questions about what our “little pea” was for Halloween. I wanted to dress him up as a pea pod, but couldn’t find a small enough costume. So instead, he was a frog. Our talented sister-in-law, Whitney, makes the cutest little beanies and sent Caleb a froggy.  It was the perfect costume for his first Halloween. Thanks Whit!

For the Cake:

  • 3 cups all-purpose flour
  • 2 teaspoons baking soda
  • 1/2 teaspoon salt
  • 1 cup butter 2 Sticks unsalted Butter, at room temperature
  • 2 cups granulated sugar
  • 2 teaspoons vanilla extract
  • 2 large eggs
  • 4 ripe bananas mashed (you should have 1 ½ - 1 ¾ cups)
  • 1 cup sour cream
  • 1 1/2 cups chopped up Reese's Peanut Butter Cups
  • 1/3 cup creamy peanut butter

For the Peanut Butter Glaze:

  • 1 1/2 cups sifted powdered sugar
  • 1/4 cup milk
  • 1/4 cup creamy peanut butter
  • 1/2 teaspoon vanilla extract


  • Preheat the oven to 350˚F. Generously butter a 9- to 10-inch (12 cup) Bundt pan and set aside.
  • In a medium bowl, whisk the flour, baking soda and salt together. Set aside.
  • In the bowl of a stand mixer, beat the butter until creamy. Add the sugar and beat at medium speed until pale and fluffy. Beat in the vanilla, then add the eggs one at a time, beating for about 1 minute after each egg goes in. Reduce the mixer speed to low and mix in the bananas. Finally, mix in half the dry ingredients all the sour cream and then the rest of the flour mixture.
  • Carefully stir in Reese's peanut butter cup pieces. Scrape half of the batter into the prepared pan and smooth the top. Swirl in half of the the peanut butter, using a toothpick. Add the rest of the batter and smooth the top. Swirl in the remaining peanut butter, using a toothpick. Pound the pan on the counter so the cake batter will settle and even out.
  • Bake the cake for 65 to 75 minutes, or until a toothpick inserted into the center of the cake comes out clean. Check the cake after about 30 minutes - if it is browning too quickly, cover it loosely with a foil tent. Transfer the cake to a rack and cool for 10 minutes before unmolding onto the rack to cool to room temperature.
  • While the cake is cooling, make the peanut butter glaze. In a medium bowl, whisk together peanut butter, powdered sugar, milk, and vanilla extract. Whisk until smooth. When the cake is cool, drizzle glaze over the top of the cake. Cut into pieces and serve.

  31. This recipe looks really good…but…I’m allergic to bananas. 🙁 I don’t suppose I could substitute something like pumpkin puree or applesauce for the bananas? I might have to experiment with that.

    1. I haven’t tried the recipe without the bananas, but I am sure you could tweak the recipe. Let me know if you try it!

  34. Oh goodness….this looks wonderful! Now I’ll need to raid the kids’ Halloween candy stash. 😉 Great post Maria and the little pea sure is cute as a button!


  35. I made this cake yesterday and it tasted as good as yours looks. Mine did not come out of the pan very well, but I still frosted it and it was delish!

  36. I rushed home and made this cake…yummy! Everyone loved it. Of course, I thought I greased my bundt pan enough (or I may need a new one), but it got stuck in there. I pieced it back together and covered the damage with some glaze. My glaze did not come out as thick as your glaze looks. The cake wasn’t going anywhere but in our bellys, so looks didn’t matter. It tasted great.

  37. I made this cake yesterday to rave… and I mean RAVE reviews. It was one of those shining moments that even I could not deny how fabulous a cook I am. 😉 I took one bite and fell in love. There were shouts of exclamation, moans of ecstasy and near tears from all who had some. Of course I’ve given credence to your website. Amazing… just amazing!

  38. I made this and brought it in to work today for my co-workers birthday (I am the resident birthday baker) and everyone LOVED. I was worried since I had never made it before so I made red velvet cookies as back-up but I didn’t even need them. This was such a fabulous cake and the perfect ratio of bananas and peanut butter. My roommate can’t eat bananas so he was super bummed he could have any because he loves peanut butter and reeses. Does anyone know if there is something I can substitute the bananas for?

  39. Just made this with leftover Valentine Reeses Peanut Butter Cups. We LOVED it. I’m not sure that there will be any left after tonight with my family of five. This recipe is definitely a repeat! Thank you!

  40. Hey, just wanted to say that I made this cake right now and it came out delicious. Excellent for any PB fans 😀

  41. I made this last night – so delicious! I didn’t have full fat sour cream, and had to substitute 1/2 cup low fat sour cream + 1/2 cup nonfat plain greek yogurt. I’m pleased to report that it came out just fine – moist, rich, delicious. I generously buttered and floured my bundt pan and it mostly came out perfectly, except for a chunk where a peanut butter cup welded to the pan. I just patched it back together and the glaze covered it up! 😀

  42. I made this. Make sure to grease all parts of your bundt pan really, really well. Mine stuck to the inner part of the pan, so I had to piece it back together. The recipe directs you to cool the cake on a wire rack before transferring it to a serving plate, but I wouldn’t . Mine stuck to the wire rack and threatened to break apart from the bottom too. Luckily I made this for my family, because I had to serve it from the wire rack.

    Next time I think I’ll either incorporate the peanut butter into the batter or leave it out all together, because I didn’t like the taste of the peanut butter streaks in the finished cake. I also think that between the glaze and the candies, the cake was peanut buttery enough. My son loved it, though!

  43. I wonder if it was just me that ended up having lots of leftover batter..I followed the direction..and i knew there were too much (i think) batter leftover while I was pouring it into my bundt pan, Is it normal? or maybe I mixed eggs with other ingredient for too long (exactly followed the direction, like beat for 1 min for each eggs) or what…dont know..I will try to make it again though and this time I will only put half of the batter so it will cook all the way. Smelled was wonderful and if it cooked all the way, I would definately enjoyed it last night 😉

  44. This is more of a question than a review, have you ever made this cake in individual bundt pans? If yes, how long did you bake and did you fill each pan about 3/4 full? I would like to make and use as individual cakes after a dinner party. For presentation, I would drizzle the dessert plate with chocolate in garnish with individual peanut butter cups.

    1. I haven’t but I am sure it would be fine. Reduce the baking time and 3/4 full sounds right. If your pan has any instructions, that would be helpful too. I am not sure the exact size you have so I can’t tell you how many it will make. Let me know if you try it! Sounds fun!

  45. Since I am recuperating from a broken ankle, I am not physically capable of standing at the counter for the prolonged length of time it would take to make this banana cake from scratch. May I make your recipe with a boxed banana cake mix or would the flavor and/or texture be negatively compromised? Also, by adding the 1 cup of sour cream to the boxed banana cake mix create a thin, overly ” runny” batter that would not satisfactorily solidify into a cake?
    I would greatly appreciate your response. I want to make this for my local police force and Veterinarians.
    Additionally, I had planned to add the Reese’s Cups and peanut butter as stated in your recipe. I simply do not know if the aforementioned would be acceptable for your recipe. I thank you in advance. Lore
