This Reese’s Chocolate Peanut Butter Earthquake Cake is a rich, gooey dessert that combines chocolate cake, a creamy peanut butter filling, and chunks of Reese’s peanut butter cups. The “earthquake” effect comes from the way the layers bake and crack, giving the cake its signature look and irresistible texture.
The cracked, uneven surface is normal and gives the cake its “earthquake” name.
For a less sweet version, use a dark chocolate cake mix.
For extra indulgence, drizzle caramel or hot fudge over slices before serving.
Store leftovers covered at room temperature for two days, or refrigerate for up to five days.
