Peanut butter and chocolate lovers, get ready to be swept off your feet. This beyond-easy cake actually "bakes" in a slow cooker.

Slow Cooker Peanut Butter Cake

Spray 4-quart slow cooker with non-stick cooking spray.

In a large bowl, beat cake mix, water, eggs, peanut butter and butter with electric mixer on low speed for 2 minutes.

To make chocolate fudge batter, place 2/3 cup of the batter in medium bowl; stir in 1/2 cup chocolate syrup.

Spoon half of the peanut butter batter in the slow cooker, followed by all of the chocolate fudge batter. Top with remaining peanut butter batter. Swirl with a knife in a circular motion.

Cover and cook on HIGH for 2 hours. Remove ceramic base from slow cooker and cool 15 minutes on a cooling rack.

Drizzle with remaining 3 tablespoons chocolate syrup and top with peanut butter cups before serving.
