  • Total Time
    Prep: 30 min. Bake: 20 min. + cooling
  • Makes
    2 dozen


  • 1 package chocolate cake mix (regular size)
  • 1-1/4 cups water
  • 1/2 cup peanut butter
  • 1/3 cup canola oil
  • 3 eggs
  • 24 miniature peanut butter cups
  • 6 ounces semisweet chocolate, chopped
  • 2/3 cup heavy whipping cream
  • 1/3 cup peanut butter
  • Additional miniature peanut butter cups, chopped


  • In a large bowl, combine the cake mix, water, peanut butter, oil and eggs; beat on low speed for 30 seconds. Beat on medium for 2 minutes or until smooth.
  • Fill paper-lined muffin cups half full. Place a peanut butter cup in the center of each cupcake. Cover each with 1 tablespoonful batter.

    Hi from Australia!I'm hoping to make these tonight for a work fundraiser tomorrow so if i could get a reply asap that would be great!The recipe calls for 1 package chocolate cake mix (regular size) - how many grams is that? My regular packets (450g) says it makes 12 cupcakes although the recipe says it'll make 24....just a little confused if it'll still work out and make 24...Also, does it matter if I use smooth or crunchy peanut butter?Thanks

    These were absolutely decadent! I made them for a Super Bowl party. They were a huge hit with kids and adults alike. The ganache frosting is awesome!

    Used butter instead of canola oil, but other than that I followed the recipe exactly. They were great!

    I just finished making these and I could not wait to frost them. But I messed up again! Recipe called for 2/3 c whipping cream so I wanted to use up the rest of the container so I put in the other 1/2 cup, big mistake! The frosting did not thicken, so I added confectionary sugar, but it still did not thicken. The frosting was delicious and I only could use a third of it. I always use milk chocolate chips. So I'll save the frosting to use over ice cream, etc. The taste was very delicious so I shared w/neighbors.

    Family loved these and they are so pretty! I also dipped the cupcakes in the warm frosting and sprinkled them with the chopped pb cups....chopped them a little finer than the picture. I was BETTER than a rock star, lol!

    Easy and fun to make! My frosting did NOT thicken up like the recipe said it would so I added 1/4 cup of confectioner's sugar and dipped the cupcake into the frosting upside down. I topped them immediately with the cut up peanut butter cups....delicious. I used only a fraction of the frosting though. I'll 1/2 the frosting recipe next time. Rave reviews from my guests.
