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

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
My kids could stop eating this delicious yummy cake. Chocolate and peanut butter can’t ever be wrong. Thank you for delicious recipe.
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?…
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!
When do you add the cocoa a SN espresso milk mixture?
Step 6 in the directions.
Excellent bundt cake. I love it… I will do this cake over and over again… Delicious. Thanks…
Thank you!
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.
I never add coffee to anything I make cuz I don’t like the taste it has
