This 4-ingredient slow cooker tax day treat is the kind of no-fuss dessert I lean on when life feels busy and a little overwhelming—like when we’re sorting receipts and filing taxes at the last minute. You literally toss raw chopped peanut butter cups into the slow cooker with three pantry-friendly ingredients, give it a stir, and let the machine do the rest. The result is a warm, gooey, chocolate-peanut-butter dessert that tastes like a cross between a lava cake and a candy bar sundae topping. It’s perfect for celebrating the end of tax season with your family, and it’s simple enough that the kids can help with the chopping and sprinkling.
Serve this warm peanut butter cup dessert straight from the slow cooker, scooped into bowls over vanilla ice cream or alongside a big glass of cold milk. It’s also wonderful spooned over brownies, pound cake, or even waffles for a fun dessert-for-dinner night. A little whipped cream and a drizzle of chocolate or caramel sauce make it extra special if you’re treating your spouse after a long day. For a lighter touch, pair small portions with fresh sliced strawberries or bananas to balance the richness.
Slow Cooker Peanut Butter Cup Tax Day TreatServings: 8
Ingredients
3 cups raw chopped peanut butter cups (about 16–18 regular-size cups)
1 can (14 ounces) sweetened condensed milk
1 cup semi-sweet chocolate chips
1 teaspoon vanilla extract
Directions
Lightly spray the inside of a 4- to 6-quart slow cooker with nonstick cooking spray to help with cleanup. This keeps the chocolate from sticking too much to the sides.
Chop the peanut butter cups into bite-size pieces. Aim for rough chunks about the size of a nickel so they hold some shape but still melt into the dessert. Scatter all the chopped peanut butter cups evenly over the bottom of the slow cooker. It should look like a thick, candy-studded layer covering the base.
In a medium microwave-safe bowl, combine the sweetened condensed milk and chocolate chips. Microwave in 20–30 second bursts, stirring after each, just until the chocolate chips are mostly melted and the mixture is smooth and glossy. You don’t need it piping hot—just warm enough to stir easily.
Stir the vanilla extract into the warm chocolate-condensed milk mixture until fully combined.
Pour the warm chocolate mixture evenly over the chopped peanut butter cups in the slow cooker, trying to cover as much of the candy layer as you can. Use a spatula to gently nudge the mixture around so it seeps down between some of the pieces, but don’t worry if a few chunks peek through on top.
Cover the slow cooker with the lid and cook on LOW for 1½ to 2 hours. Do not stir during this time. The peanut butter cups will soften and melt into the chocolate mixture, forming a thick, spoonable dessert. The edges will look a bit set and fudgy, while the center stays soft and gooey.
After about 1½ hours, check the texture. If you like it extra gooey, it may be ready now. If you prefer it a little thicker and more set, continue cooking up to 30 minutes more, checking every 10 minutes so it doesn’t scorch around the edges.
Once it reaches your preferred consistency, turn the slow cooker to WARM. Let the dessert sit, covered, for 10–15 minutes to cool slightly and thicken. This rest time helps it scoop more neatly while still staying wonderfully melty.
Serve the dessert warm, scooped straight from the slow cooker into bowls. It’s especially delicious over vanilla ice cream or topped with whipped cream. Store any leftovers in a covered container in the refrigerator for up to 3 days. Reheat gently in the microwave in short bursts, stirring between each, until warm and smooth again.
Variations & Tips
For a less sweet version, use dark chocolate chips instead of semi-sweet, or swap half the peanut butter cups for salted roasted peanuts to add crunch and balance. If you have peanut allergies in the house, you can substitute chopped chocolate candies or peanut-free chocolate-covered candies in place of the peanut butter cups—just keep the total amount the same so the texture stays right. For picky eaters who don’t like big chunks, chop the peanut butter cups into smaller pieces and gently stir the dessert once at the very end of cooking to distribute them more evenly. You can also swirl in 2–3 tablespoons of creamy peanut butter or almond butter into the warm mixture before serving for extra nutty flavor. If you want a firmer, fudge-like treat, line a small pan with parchment, pour the hot mixture in, and chill until set, then cut into squares. Food safety tips: Always cook this on LOW as directed; cooking on HIGH can cause the chocolate and condensed milk to scorch and separate. Keep the slow cooker covered while cooking to maintain a safe, even temperature. Allow leftovers to cool, then refrigerate promptly within 2 hours. Reheat only the portions you plan to eat, and discard if the dessert develops an off smell or appearance. Be cautious when handling the slow cooker crock and lid, as both become very hot—use oven mitts and keep kids away from the hot surfaces.
