Today’s featured dessert is a celebration of candy — literally. This Peanut Butter Addiction Cake is entirely covered in peanut butter cups and other candy, making it true eye candy and a dream for anyone who loves the classic peanut butter and chocolate pairing. Between the rich dark chocolate cake layers, silky chocolate ganache, creamy peanut butter buttercream, and an abundance of peanut butter cups in multiple sizes, this creation is an indulgent, over-the-top treat that’s hard to resist.
This cake was designed and baked by Jennifer White of Cup A Dee Cakes in Georgia. Jennifer describes the cake as two tiers, each tier made from a three-layer dark chocolate cake. Between the cake layers she used a layer of ganache followed by a layer of peanut butter buttercream, and then finished the exterior with chocolate buttercream. The combination of textures — dense chocolate cake, smooth ganache, and fluffy peanut butter buttercream — creates a deeply satisfying flavor profile that fully embodies the Reese’s-inspired concept.
For the exterior decoration, Jennifer leaned into abundance. She used one full case of large peanut butter cups, two bags of medium-sized cups, and two bags of minis. Some imperfect candies were set aside and didn’t make it onto the cake — which speaks to the level of careful selection she applied. The build began with an initial pattern, but as placement progressed she and her team filled every available space with candy, prioritizing coverage and visual impact over strict symmetry. The result is a cake covered edge to edge with peanut butter cups that reads as both playful and decadent.
Visually, the effect is immediate: a cascade of chocolate and peanut butter hues with varying shapes and sizes creating texture and depth. The ganache peeking through at the cut edges offers a glossy contrast to the matte buttercream, while the peanut butter cups provide a three-dimensional quality that invites sampling. This cake was requested by a bride and groom who specifically wanted a straightforward cake with lots of peanut butter cups — and Jennifer delivered exactly that, with an emphasis on maximum candy coverage rather than ornate piping or elaborate sugar work.
From a practical perspective, assembling a candy-covered cake at this scale requires planning. The heavier candy pieces are best placed on secure, level tiers; smaller pieces can be tucked into gaps for a cohesive look. Using a firm, chilled layer of chocolate ganache beneath the buttercream helps stabilize heavy candies and prevents them from sliding. Additionally, having extras on hand is essential because some candies will inevitably be imperfect or unsuitable for display. The creative decision to initially follow a pattern and then switch to filling every space was a smart way to balance design intent with visual abundance.
Taste-wise, this cake satisfies several cravings at once: the deep cocoa notes of the dark chocolate cake, the sweetness and smoothness of the chocolate ganache, and the salty-sweet, creamy peanut butter buttercream. Each forkful offers contrast in texture and flavor, and the presence of the peanut butter cups amplifies that classic combination. For anyone who grew up loving peanut butter and chocolate, this cake is a nostalgic celebration and a bold, modern take on those flavors.
A big thank-you to Jennifer White and her team at Cup A Dee Cakes for sharing this Peanut Butter Addiction Cake. Their dedication to flavor, texture, and playful presentation makes this a standout wedding cake idea for couples who want something fun, indulgent, and unapologetically candy-forward. For those inspired by this design, consider how the balance of ganache, buttercream, and candy placement can be adjusted to suit personal tastes while keeping the joyful spirit of the original concept.
