Yellow cake is spiked with peanut butter, hot fudge, topped with a peanut butter glaze, more hot fudge, and sprinkled with peanut butter cups!! It’s rich, decadent, SO EASY, and made in a slow cooker!!
This is one of the best cakes I’ve made in ages despite it not being the most photogenic cake. It’s not neat and dainty. It’s messy but fabulous.
Yellow cake is spiked with peanut butter, hot fudge, topped with a peanut butter glaze, more hot fudge, and sprinkled with peanut butter cups. You’re welcome.
With the dog days of summer upon us, I’m all about not turning on my oven if I don’t have to. Enter an easy slow cooker cake.
This isn’t the first time I’ve made dessert in a slow cooker but it’s been awhile and this cake reminded me I should do it more often.
The cake is so soft, moist, and tender from the peanut butter and hot fudge swirls that are baked inside that cake but the literal icing on this cake is the peanut butter glaze that’s swirled with hot fudge.
When the glaze and hot fudge are applied to the warm cake and you dive in, it’s incredible. Warm melty peanut butter is heaven on earth.
It’s a great cake to make before the start of a party because when the appetizers and dinner are finished, the cake is ready. Everyone can dig right in with spoons into this warm, gooey, rich, decadent cake.
I always use slow cooker liners because they save so much cleanup time and highly recommend one for the cake.

Slow Cooker Peanut Butter Cup Swirl Cake
Ingredients
Cake
- one 15.25-ounce box yellow cake mix
- 1 cup water
- 3 large eggs
- heaping 1/2 cup creamy peanut butter
- ÂĽ cup unsalted butter, softened
- ½ cup hot fudge sauce, not thin chocolate sauce
Glaze and Toppings
- 1 cup confectioners’ sugar
- â…“ cup creamy peanut butter
- ÂĽ cup cream or milk, plus more as necessary for consistency
- â…“ cup hot fudge
- 20 peanut butter cups miniatures, unwrapped and cut in half (minis may be substituted)
Instructions
- Cake – Line a 6-quart oval slow cooker with a slow cooker liner or spray with cooking spray; set aside.
- To a large bowl, add the cake mix, water, eggs, peanut butter, butter, and beat with an electric handheld mixer on medium-high speed for about 2 minutes; stop to scrape down the sides of the bowl as necessary. The batter will be thick.
- Turn just over half of the batter out into prepared slow cooker.
- Add the hot fudge and top with the remaining batter.
- Using a knife or rubber spatula, lightly swirl up and back the length of the slow cooker.
- Cook on high for about 1 hour 45 minutes, or until a knife inserted in the center comes out clean, or with a few moist crumbs. Because all slow cookers vary, start checking at 1 hour 30 minutes. When cake is done, remove the ceramic base from slow cooker and place the base on a wire rack to cool. While cake cools, make the glaze.
- Glaze and Toppings – To a medium bowl, add the confectioners’ sugar, peanut butter, milk, and whisk until smooth. Add additional milk as necessary until desired glazed consistency is achieved. Turn glaze out evenly over the cake.
- Evenly drizzle the hot fudge over over the glaze and lightly swirl it into the glaze.
- Evenly sprinkle the peanut butter cups and serve immediately. Cake is best fresh but will keep airtight for up to 5 days.
