These chocolate whoopie pies are a nostalgic treat with a fun twist! Soft, cake-like chocolate rounds are sandwiched with a creamy peanut butter filling that’s just the right amount of sweet. This recipe starts with my mom’s moist chocolate cake and transforms it into RIDICULICIOUS handheld desserts. They’re great for parties, gifting, or a make-ahead freezer treat—my husband even loves them straight from the freezer!
Preheat oven to 350°F (177°C). Line baking sheets with parchment.
In a large bowl, whisk flour, cocoa powder, sugar, baking soda, and salt.
In another bowl, whisk eggs, buttermilk, coffee, oil, and vanilla. Add optional sour cream if using.
Stir wet mixture into dry until combined. Batter should be thick but scoopable.
Use a medium cookie scoop to place batter on prepared sheets, leaving space between.
Bake 9–11 minutes or until tops spring back lightly. Cool completely before filling.
To Make the Peanut Butter Filling:
Beat butter and peanut butter until fluffy—about 2–3 minutes.
Add powdered sugar and salt, then beat on low. Increase to medium-high and whip until smooth.
Add vanilla and 2 tablespoons of cream. Beat until fluffy. Add more cream if needed.
To Assemble:
Match cooled cakes into pairs.
Pipe or spread filling onto one cake, top with the other, and gently press to sandwich.
