These Chocolate Peanut Butter Cupcakes start with a doctored dark chocolate fudge cake mix, get extra moisture and richness from sour cream, pudding, and oil, then hide a surprise core of mini Reese’s Pieces under a swirl of peanut butter frosting and a Reese’s Mini on top. You end up with ultra-soft bakery‑style cupcakes that taste like a Reese’s explosion in every bite.
Why You’ll Love These Chocolate Peanut Butter Cupcakes
You’ll love how the boxed cake mix plus instant pudding and sour cream hack creates dense, moist, chocolate cupcakes that never taste like they came from a box. The batter bakes with a tight, tender crumb—sturdy enough to core and fill, but soft enough to feel fudgy rather than cakey.
The Reese’s Pieces center adds crunch and salty‑sweet peanut butter pockets, contrasting beautifully with the smooth chocolate crumb and creamy peanut butter frosting. Topping each cupcake with a Reese’s Miniature turns them into show‑stopping party treats that look bakery‑bought with relatively little effort.
