This 3-ingredient slow cooker dessert is the kind of easy summer treat that feels almost too simple to work, yet it turns into a rich, scoopable peanut butter cookie dessert with barely any effort. It is perfect for busy days when turning on the oven sounds miserable, and using uncooked peanut butter sandwich cookies gives it a fun shortcut feel that makes it especially appealing for potlucks, casual family nights, or those evenings when you want something warm and sweet without making a big mess.
Serve this dessert warm straight from the slow cooker with vanilla ice cream, whipped topping, or a drizzle of chocolate syrup. It also pairs really well with cold brew coffee, iced tea, or a glass of milk, and if you want to dress it up a little, a sprinkle of chopped peanuts or mini chocolate chips on top adds a nice bit of crunch.
3-Ingredient Slow Cooker Summer Peanut Butter Cookie Dessert
Servings: 8
Ingredients
1 package uncooked peanut butter sandwich cookies
1 can sweetened condensed milk
1 container whipped topping
Directions
1. Lightly grease the inside of your slow cooker. Arrange the uncooked peanut butter sandwich cookies in an even layer across the bottom.
2. Pour the sweetened condensed milk evenly over the cookies, making sure most of the surface is covered.
3. Spoon the whipped topping over the top and gently spread it into a loose, even layer.
4. Cover and cook on low for 2 to 3 hours, or until the cookies are soft and the dessert is warm and set around the edges.
5. Turn off the slow cooker and let the dessert rest for 10 to 15 minutes before scooping and serving.
Variations & Tips
Chocolate Drizzle: If you want this dessert to feel a little more special, finish each serving with warm chocolate syrup or a handful of mini chocolate chips. Peanut butter and chocolate always work, and it makes this taste even more like a treat you picked up from a bakery.
Frozen Topping Shortcut: Let the whipped topping thaw before adding it so it spreads easily and evenly. I like to move it from the freezer to the fridge earlier in the day, which makes assembly much faster after work.
Crunchy Finish: Add chopped roasted peanuts right before serving for contrast. Since the dessert is so soft and rich, a crunchy topping keeps every bite from feeling too heavy.
Make It Neater to Serve: If you want cleaner scoops, line the slow cooker with a parchment slow cooker liner before adding the cookies. It also makes cleanup easier, which is always a win on a busy night.
