Candy Placement – Reserve a few chopped peanut butter cups to press onto the drizzle for extra visual appeal.

How to Make Mini Chocolate Peanut Butter Bundt Cakes

Step 1: Preheat & Prep Pans
Preheat the oven to 350°F.

Grease and lightly flour two 6-cup mini Bundt pans (or 12-cup muffin tins work in a pinch).

Step 2: Combine Cake Mix & Wet Ingredients
In a large bowl, whisk together the chocolate cake mix, eggs, water, and oil until smooth.

Fold in the peanut butter until streaks remain for swirled effect.

Step 3: Add Candy
Gently fold in 1 cup chopped mini peanut butter cups, reserving a handful for garnish.

Step 4: Fill Pans
Divide batter evenly between the prepared pans, filling each two-thirds full.

Use a small spatula to level the tops.

Step 5: Bake to Perfection
Bake for 20–25 minutes or until a toothpick inserted into the center comes out clean.

Rotate pans halfway through bake for even browning.

Step 6: Cool & Unmold
Let cakes cool in the pans on a wire rack for 10 minutes.

Run a thin knife around the edges, then invert to release each cake.

Cool completely before glazing.

Step 7: Make the Drizzle
In a microwave-safe bowl, heat ¼ cup chocolate chips and 2 Tbsp peanut butter in 15-second intervals, stirring until smooth.

Drizzle over cooled cakes and immediately top with reserved chopped peanut butter cups.

FAQs

Can I use homemade chocolate cake instead of mix?
Yes—use your favorite recipe and follow the same method of adding peanut butter and cups.

How do I prevent the peanut butter from sinking?
Fold the cups gently into the batter and fill pans carefully to suspend them evenly.

Can I omit the candy cups?
Absolutely—boost mini chips or chopped nuts for crunch instead.

Why didn’t my cakes release cleanly?
Ensure pans are well-greased and cooled at least 10 minutes before unmolding.

Is there a dairy-free option?
Use dairy-free chocolate chips and a vegan cake mix; check peanut butter is vegan-friendly.

Can I make these ahead for a party?
Yes—cakes can be made 1–2 days in advance and stored in the fridge; add drizzle just before serving.

What’s the best way to transport them?
Wrap each cake gently in parchment and place in a shallow, lined container to keep decorations intact.
