Chocolate bundt cake with a surprise! There is a swirl of peanut butter filling inside the chocolate cake!

Peanut Butter Chocolate Bundt Cake

How can you make chocolate bundt even better?

You could spike the cake with some whiskey or rum. Perhaps, add additional flavors like peppermint or caramel. Or, you could swirl in peanut butter!

This peanut butter chocolate bundt cake is adapted from this older chocolate glazed whiskey bundt cake.

Chocolate Bundt Cake with peanut butter

Chocolate and peanut butter is such a delicious combination. The sweetness and slight bitterness of dark chocolate pairs wonderfully with the nutty peanut butter.

For best results, generously butter the 10-cup bundt pan before adding the batter. For extra measure, you may lightly dust the buttered pan with flour as well.

Chocolate Glaze

The chocolate glaze is a simple mixture of dark chocolate, butter, and light corn syrup. The three ingredients are melted together to create a rich and creamy glaze.

Use a double boiler (bain marie) or gently heat the chocolate and butter in the microwave.

The corn syrup (or glucose) helps to keep the chocolate glaze shiny and soft. The chocolate glaze will not harden as it sits out.

Peanut Butter Cake Filling

A word of warning- the peanut butter cake filling is not creamy. It will bake up to a texture similar to the chocolate cake.

The peanut butter filling will be a little crumbly.

For best results, use a no-stir homogenous smooth peanut butter.

Peanut Butter Chocolate Bundt Cake

I was inspired to make a bundt cake after seeing the latest issue of Martha Stewart Living.  On the cover there is a beautifully sliced and styled coffee cake.  The styling of this bundt cake is in homage that one.

Ingredients

Chocolate Cake:

  • 4 oz unsweetened chocolate, roughly chopped
  • 2 Tbsp instant espresso powder
  • 2 Tbsp unsweetened cocoa powder
  • ¾ cup whole milk
  • 1 cup unsalted butter, room temp
  • 1 ½ cup granulated sugar
  • 3 large eggs
  • 2 cups all-purpose flour
  • 1 tsp baking soda
  • ½ tsp kosher salt

Peanut Butter Cake Filling:

  • ¼ cup unsalted butter, room temp
  • ¼ cup smooth peanut butter
  • 2 Tbsp granulated sugar
  • 1 large egg, beaten
  • ½ cup all-purpose flour
  • ¼ cup whole milk
  • ¼ tsp kosher salt

Chocolate Glaze:

  • 4 oz dark chocolate, roughly chopped
  • ¼ cup unsalted butter
  • 1 Tbsp glucose, or light corn syrup

Peanut Butter Glaze:

  • 2 Tbsp smooth peanut butter
  • 2-3 Tbsp whole milk
  • ¾ cup confectioners' sugar, sifted
  • pinch kosher salt

Instructions
 

Chocolate Cake:

  • Preheat oven to 350°F.  Generously butter a 10-cup bundt pan and set aside.
  • In a microwave safe bowl, heat unsweetened chocolate at half power at 30 second intervals.  Stir often.  Heat until chocolate is melted.  Set aside.
  • In a glass measuring cup, stir together instant espresso powder and cocoa powder.  Add enough hot water until liquid mixture measures 1 cup.  Stir until powders are dissolved.  Add milk and let cool.
  • In the bowl of a stand mixer with a paddle attachment, cream butter and sugar until light and fluffy.  Add eggs one at a time, making sure egg is incorporated before adding the next.  Scrape down bowl as needed.
  • Add slightly cooled melted chocolate. Continue to mix on low-medium speed until combined.
  • In a medium bowl, whisk together flour, baking soda, and salt.  With the mixer on low, add 1/3 of milk mixture, then 1/2 of flour mixture.  Repeat, ending with the milk mixture.  Mix until combined.

Peanut Butter Cake Filling:

  • In a medium bowl, cream together butter and peanut butter until smooth.  Add sugar and mix until combined.  Add half of the beaten egg.  Discard other half of egg.  Mix until combined.
  • Fold in flour and salt.  Add milk and stir to combine.  Mix until flour is incorporated.

Cake Assembly:

  • Add half of chocolate batter to prepared bundt pan.  Distribute peanut butter cake filling on top of chocolate layer.  Swirl with knife to spread out peanut butter batter.  Add remaining chocolate batter to cover peanut butter batter.
  • Bake for 50-60 minutes, until toothpick inserted in cake comes out clean.  Let cool in pan for a couple of minutes before unmolding.  Let cool to room temperature of wire rack.

Chocolate Glaze:

  • Over a double boiled, melt together chocolate and butter until smooth.  Alternatively, you can microwave it at half power at 30 second intervals until melted.
  • Remove from heat and whisk in glucose.  Pour over cooled bundt cake.

Peanut Butter Glaze:

  • Stir together sifted powdered sugar, peanut butter, and salt.  Add milk and stir until smooth.  Add additional milk if glaze is too dry.  If glaze is too thick, add additional sifted powdered sugar.  Drizzle peanut butter glaze over chocolate glazed bundt cake.

Notes

The peanut butter cake filling is not creamy.  It will be more cake-like in texture.

    Hi I made your cake last night and it looked so great. The chocolate part was great. It was moist and fluffy. On the other hand the peanut butter swirl was not so much I don’t know where it went wrong. From the picture I thought it would be creamy, but instead it was very thick or eggy like. Next time i’ll try putting baking powder in the peanut butter and hopefully it would be as fluffy as the cake.

      Hi Hope, thanks for trying out the recipe! The peanut butter swirl isn’t creamy. It’s supposed to be a peanut butter cake inside the chocolate cake.

      I agree. The peanut butter filling is terrible!!!!!

    This looks DELICIOUS!! But I’m having to eat dairy free for my little one. Do you think it would work as well to supplement coconut milk and oil in place of the whole milk and butter? And if I try it, I’ll let you know how it goes. :)

      Hi Rebecca! Sorry, I’m not sure how coconut milk and oil would work in the recipe. However, I’d love to hear about it if you try it out!

    I’m a little late to the party, but I wanted to let you know that I made the bundt cake for my wife’s birthday and it was a hit. I was told that I screwed up big time, as I will have to make this every year for her birthday. Thanks Maryanne!

    attempted to bake this now twice to disastrous results both times. Cake has come out dense and pastry both times. I thought this was a result of over beating so in lieu using the stand mixer I hand mixed it the second time and it was still a disaster. Not sure where this goes wrong but it’s really a shame.

      Hi Matt, I’m sorry to hear that. I’ve made this recipe several times with consistent results. Perhaps the unsweetened chocolate was burned during melting. If the chocolate is heated out of temper, it will become grainy.

    What happens if I were to omit the espresso??

      The espresso powder highlights the chocolate flavors. You can easily omit it, if you’d like.

    Way too much espresso powder. Batter was so strongly coffee flavored I had to punt on the peanut butter filling which was unfortunately the point. Made a nice chocolate mocha Bundt cake, if that is what you want!

    This looks yummy for PB & chocolate lovers like myself…. I’m thinking about adding cream cheese to the PB filling….some how, may have to adjust other ingredients to keep a strong peanut buttery flavor?…

    well if I make this cake and the only thing I would do is omit the coffee since I don’t drink the stuff and I won’t go to the store and buy the instant
