Ingredients you’ll need for this recipe

Ingredients used to make a peanut butter cake including buttermilk, sugar, peanut butter, flour, chopped peanuts, butter, eggs, baking powder, and water. Hostess At Heart
  • Unsalted Butter. You can use salted butter if necessary, but because peanut butter also has salt in it, the flavor can change. You can also use a non-dairy butter.
  • All-Purpose Flour.
  • Creamy Peanut Butter. This recipe needs processed regular peanut butter. The natural peanut butter varieties will not work.
  • Eggs. We use large eggs.
  • Buttermilk. Don’t have buttermilk? No problem! Just measure the same amount of whole milk and add a teaspoon of white vinegar or lemon juice. Stir and let it sit for 5 minutes.
  • Granulated Sugar.
  • Water.
  • Baking Powder.
  • Vanilla Extract. Pure vanilla is what we prefer but use imitation if that’s what you have.
  • Powdered Sugar. It is sometimes called confectioner’s sugar or icing sugar.
  • Chopped Roasted Peanuts.

How To Make Peanut Butter Bundt Cake Recipe

Please note, that the printable recipe card has ingredient quantities, complete instructions, and nutritional information. The following is a quick overview of the recipe.

Step One. Get everything ready.

Pull out your ingredients, preheat your oven, and prepare your bundt pan.

Step Two. Cream the liquid ingredients.

We use an electric mixer to combine peanut butter with the butter. Mix on medium speed until smooth and creamy. Add the eggs, vanilla, and buttermilk and mix at low speed until combined.

Step Three. Add the remaining ingredients.

Whisk flour, sugar, and baking powder together in a large bowl. Gradually mix the dry ingredients and the water to the peanut butter batter and beat on low until smooth, about 3 minutes.

Step Four. Bake your Peanut Butter Bundt Cake Recipe.

Pour the batter into the prepared 10-inch bundt pan and bake. Cool in the bundt pan for 15 minutes before turning the cake out onto a serving platter.

Step Five. Make the Peanut Butter Glaze.

Small bowl filled with powdered sugar, peanut butter, and buttermilk for a peanut butter glaze.

Meanwhile, make the peanut butter glaze. Whisk everything together in a small bowl, including the remaining buttermilk. Spoon it over the top of the cake, letting it drizzle down the sides. Garnish with the roasted peanuts.

Note: You want the glaze to be thin enough to run down the sides. If your glaze is too thick add liquid. If it’s too thin add powdered sugar.

Variations and Substitutions

  • Some cakes cook better in a bundt pan because more of the cake is in contact with the pan, assuring that the cake cooks evenly. You can use any bundt pan, but ensure it has a 10-cup capacity. If you’d rather not use a bundt pan, our free pan conversion may be helpful.
  • Add Reese’s pieces, peanut butter chips, chocolate chips, or butterscotch chips to level up your cake.
  • If you love the combination of chocolate with peanut butter, you can replace the peanut butter icing with a chocolate ganache, top with mini peanut butter cups, or add semi-sweet chocolate chips to the peanut butter cake batter.

Hostess Tips for the Perfect Peanut Butter Bundt Cake Recipe

  • To make sure everything blends more evenly, the milk and eggs should be at room temperature.
  • Don’t over-mix the batter. The liquid ingredients should be beaten until light and fluffy, but everything else is only mixed until incorporated.
  • Attention to detail will prevent your cake from sticking. Bundt pans have nooks and crannies, so make sure you grease and flour the pan thoroughly so that your cake does not stick to the sides and tear getting out. I get the best results using shortening instead of baking spray.
  • Set your bundt pan on a baking sheet so that removing the bundt pan from the oven is easier. 
  • Turn the cake in the oven halfway through. Since it is a round cake, this will help it bake and brown more evenly.
  • Don’t overbake the cake. When a toothpick or cake tester comes out with a few moist crumbs, it’s ready. The cake stays in the pan for about 15 minutes to finish cooling, and it will set as it cools. Don’t skip this step.

Keyword: Bundt Cake
Servings: 16

Ingredients
 
 

  • 3/4 cup unsalted butter room temperature
  • cups all-purpose flour plus a teaspoon for the pan
  • 3/4 cup creamy peanut butter divided
  • 4 large eggs
  • 3/4 cup buttermilk room temperature, divided
  • 2 cups granulated sugar
  • 1/2 cup water
  • 1 tbsp baking powder
  • 1 tsp vanilla extract
  • 1 cup powdered sugar (confectioners or icing sugar)
  • 1/4 cup chopped roasted peanuts

Instructions
 

  • Preheat your oven to 350 °F. Lightly grease a 10-inch bundt pan and sprinkle it with flour.
  • In a large mixing bowl, beat a 1/2 cup of the peanut butter and the butter together on high until smooth and creamy, about 2 minutes.
  • Add the eggs and just 1/2 a cup of buttermilk and continue beating on high until combined, about 1 minute.
  • Add the flour, sugar, water, baking powder and vanilla and beat on low until smooth, about 3 minutes.
  • Pour the batter into the prepared pan and bake for 45 minutes or until an inserted toothpick can be removed clean. *See Notes
  • Cool in the pan for 15 minutes before flipping it out onto a cooling rack to cool completely. Turn it out on a cake plate and glaze.
  • Meanwhile, we’ll make the glaze. In a small mixing bowl, whisk together the confection sugar, the remaining peanut butter and the remaining buttermilk.
    Spoon the glaze over the top of the cooled cake and allow it to drip down the sides. Sprinkle the glaze with the chopped peanuts and enjoy!

Notes

You want to use a 10-cup bundt pan and only fill it 3/4 full. If you have extra batter, make cupcakes!
Putting the bundt pan on a baking sheet before placing it in the oven makes turning the cake and removing it from the oven easier.
