Peanut Butter Rice Krispie Treats These Rice Krispie Treats are for the peanut butter and chocolate lover! They’ve got peanut butter, mini Reese’s® cups, and a soft peanut butter-chocolate topping. They’re gooey, crunchy, and rich. They’re also quick and easy with no baking required. We make Rice Krispie Treats year-round, but they get made more frequently in the summer when we’re craving something sweet but don’t want to heat up the house with the oven. **Note: Rice Krispies, Fruity Pebbles, and Reese’s Cups are trademarked brands of several cereal and candy companies. We use these names in our recipe for easy identification purposes, but any other similar product can be substituted.** How to make these treats Line a pan. These bars are gooey and sticky! For easier removal and less mess, line the pan with parchment paper or foil. I recommend a 9-x-9-inch instead of an 8-x-8-inch pan for these bars since they are quite thick even in the wider pan. The smaller pan makes the bars too tall and more difficult to eat. I personally love this 9 x 9-inch cake pan for this recipe. Create the sticky marshmallow base. This mixture consists of butter, brown sugar, heavy cream, marshmallows, and peanut butter (all super wholesome ingredients, right?!) This is the sticky base that will hold the bars together. Add some flavor enhancements. Off the heat, we add in a little salt and vanilla extract which serves to amp up the flavor of these Peanut Butter Rice Krispie Treats. Pour marshmallow mixture over cereal. Then gently stir to combine. Add the mix-ins — Reese’s minis and a few more miniature marshmallows. Both will get gooey and melt a bit. Load the mixture into the prepared pan and gently press into one even layer. Add chocolate peanut butter topping. Last, but not least, we melt chocolate chips with peanut butter to create a soft chocolate topping for the bars. I use the microwave to melt this mixture — when microwaving chocolate, microwave in short bursts and stir the chocolate often. Remember, the mixture is still melting even outside of the microwave. Peanut Butter Rice Krispie Treat tips Low heat: When marshmallows are exposed to high heat, they harden and will make the bars as hard as a rock. The lower the heat, the longer it takes for the marshmallows to melt, but the better the bars will turn out. Use extremely fresh marshmallows: The fresher the marshmallows, the softer and more enjoyable the Peanut Butter Rice Krispie Treats will be. I generally buy marshmallows the same day I make these. Pro-tip: When purchasing marshmallows, gently press on the bags to feel for the softest marshmallows. Don’t overcook the marshmallow mixture: Stir over low heat until the marshmallows are just melted and then immediately move them from the heat. It’s also important to stir the marshmallows constantly while they are melting. Avoid compressing: Don’t push the cereal mixture into the pan. Instead, place them in the pan and gently press them down. The less you compact these Peanut Butter Rice Krispie Treats, the better they will be. When bars are heavily compressed, it makes the treats too firm and not as enjoyable to eat. Variation ideas If unable to find Reese’s “minis,” Reese’s Miniatures, chopped up (into quarters) will work great. (Here’s the difference between the two) Swap out the Reese’s minis for peanut butter chips or Nestle’s combo of peanut butter + chocolate chips. For the truly peanut butter obsessed, add a layer of peanut butter right on top of the bars before adding the chocolate. Simply spread a few tablespoons of peanut butter right on top of the bars. Peanut Butter Rice Krispie Treat storage These bars are best (texture and taste-wise) within the first couple of days (we like them best on day 1). Keep the bars in an airtight container at room temperature while storing. Freezing: The same day the bars are made (once the chocolate topping has fully set), you can freeze these bars. Cut into even-sized bars and wrap each treat in a square of wax paper and then plastic wrap. Place the wrapped treats in a resealable freezer bag. Store in the freezer bag for up to 6 months. Thawing: Thaw the Peanut Butter Rice Krispie Treats by removing an individual bar from the freezer and setting them out on the counter for 15-20 minutes or until it reaches room temperature.
