ingredients for Mini Chocolate Bundt Cakes

What You’ll Need

Besides the peanut butter chips, you won’t need any special ingredients to make these Mini Chocolate Bundt Cakes.

For the cake:

  • All-purpose flour
  • Baking powder
  • Baking soda
  • Salt
  • Butter – Set out the butter about half an hour before baking to allow it to soften.
  • Granulated sugar
  • Eggs – Set out the eggs before you begin baking so they won’t be completely cold when added to the batter.
  • Unsweetened chocolate – Use good quality chocolate for the best results. You can melt the chocolate in a double boiler, or in the microwave. For the latter, place the chocolate in a microwave-safe bowl, and heat at half-power in 30-second increments until the chocolate melts when stirred. Let it cool before adding it to the batter.
  • Vanilla extract
  • Milk – Whole or 2% milk works best.
  • Peanut butter chips – This is all you’ll need for a simple peanut butter filling. Look for these with the chocolate chips and other flavored chips.

For the glaze:

  • Cocoa powder – I prefer natural cocoa powder for this glaze, but either natural or Dutch-process will work because it’s being used solely for flavor and not its baking properties. Natural cocoa powder will give a milder flavor, while Dutch-process will provide a bolder flavor more like bittersweet chocolate. Be sure to use unsweetened cocoa powder, not a sweetened cocoa mix. Sift it if needed.
  • Confectioners’ sugar – Sift the sugar for the smoothest glaze.
  • Milk – Again, whole or 2% milk will work best.

How to Make Mini Chocolate Bundt Cakes

These little chocolate cakes are simple to make using the creaming method. You’ll need a few mixing bowls, a hand or stand mixer, and mini Bundt pans.

Prepare for baking. Heat the oven to 350°F. Thoroughly grease 12 mini Bundt cups, each with a 1-cup capacity. I prefer a baking spray with flour, like Baker’s Joy or Pam Baking. If you aren’t sure what size your pans are, measure 1 cup of water and pour into one of the cups until full. However much water you used is the capacity of the cups of your Bundt pan.

Combine the dry ingredients. Whisk together the flour, baking powder, baking soda, and salt. Set aside while you mix the wet ingredients.

Mix the wet ingredients. Use a hand or stand mixer to beat the butter and sugar until light and fluffy. Add the eggs, one at a time, and mix well after each. Mix in the chocolate and vanilla.

Add the dry ingredients and milk to the wet ingredients. Reduce your mixer’s speed to low. Add the flour in three portions, alternating with two portions of the milk. Mix the batter just until combined.

Assemble the cakes. Fill each Bundt cup about half full. Scatter peanut butter chips around the center. Then top with the remaining batter.

Bake the cakes. The cakes will need 18-20 minutes to bake thoroughly. You can check for doneness with a wooden pick or a cake tester. It will come out clean when the cakes are done.

Cool the cakes. Place the pan on a wire rack to cool for about 5 minutes. Then transfer the cakes from the pan to a rack to cool completely before glazing.

Make the glaze. Mix the cocoa powder and confectioners’ sugar. Add 2 tablespoons of milk, and stir until combined. If needed, add more milk, a small amount at a time, until the glaze is the consistency you like. The end result should be thick but pourable. If it gets too thin, add a little confectioners’ sugar.

Add the glaze to the cakes. Spoon the glaze over each cooled cake. Then let the glaze set before serving.

Recipe Variations

Here are some ideas for tweaking this recipe for some variety.

  • Use different flavor chips. Try butterscotch, cinnamon, white chocolate, or some other flavor if you like. For a serious chocolate experience, add chocolate chips!
  • Omit the peanut butter chips to focus the flavor on chocolate.
  • Skip the glaze. A simple dusting of confectioners’ sugar is a simple alternative.
  • Add a garnish. Sprinkle some chopped peanuts on top of each cake for some crunch, or serve with a few more peanut butter chips scattered on top of and around each cake.

Tips for Success

This is a pretty straightforward recipe, making it a good choice for bakers of all skill levels. Here are some tips to help make sure your cakes are the best they can be!

  • Measure accurately. Use a kitchen scale to measure by weight if possible. Otherwise, use the spoon and sweep method to measure the dry ingredients and sugar.
  • Use a light-colored metal pan. These pans will bake the cakes more evenly.
  • Grease the pans well. Bundt pans have lots of nooks and crannies, so be sure to get them completely covered. I have the most success with a cooking spray with flour.
  • Sift the confectioners’ sugar and cocoa powder. While not an absolute requirement, sifting those two ingredients will make the glaze extra smooth.

How to Store Chocolate Mini Bundt Cakes

Stored in an airtight container, these cakes should keep at room temperature for up to 3 days. If possible, store the cakes and glaze separately so the cakes don’t get soggy.

For a few more days’ storage, you can refrigerate the cakes. Set them out on the kitchen counter for a couple of hours to bring them to room temperature for serving.

If you’d like to freeze the unglazed cakes, first cool them completely. Then wrap each cake in plastic wrap. Wrap again in aluminum foil or place in a freezer-safe storage bag or container. Stored properly, these cakes should keep in the freezer up to 3 months. Thaw overnight in the refrigerator.

  1. Hard to believe we’ve been doing this for a year now! I was drooling over these little cakes at Flickr so had to come over and check them out! 🙂

  2. They look incredible. Happy Blog Birthday!

  3. That’s an excellent cake for a first blog birthday, looks great!

    Those little bundt cakes look delish. PB & chocolate is one of my favorite combinations.

  6. These look gorgeous! Like all men, my husband would love the choco-peanut butter combination.

  7. These mini-cakes are delicious if you like a hint of peanuts. Peanut chips are peanut butter, way toned down. I like the peanut butter itself with cream cheese, milk and other additives. The chips seem to fall short, though.

  8. These look sooo good. I love my mini bundt pans for parties. It does make the whole dessert thing much easier when your guests can just pick one up.

  9. My bundt pan has 3 molds. Do I just cook the cakes longer or is this not recommended? I would say they are about 2 cups each. Thank you.

    • Hi, Kay. I’ve not made these in a larger pan, so I can’t say how well it would work. You’d definitely need to add to the baking time if you’re making them that much larger, but it may take some testing to get them just right.
