Reeseโs Stuffed Peanut Butter Rice Krispie Treats!
Iโve loved Rice Krispie Treats since I was little. My mom made them often, and we always argued over who got to scrape the last marshmallow from the pot. When I started making them myself, I quickly learned how fun it was to play around with flavors. Once I added peanut butter, I knew I had found my favorite. Between the gooey marshmallows, the mini Reeseโs cups tucked throughout, and the thick peanut butter chocolate topping, these bars are hard to beat.
If you want to try other fun versions, check out my Fruity Pebbles Rice Krispies Treats, Rice Krispie Ice Cream Bars, or my Chocolate Rice Krispie Treats. Each one is simple, unique, and so delicious.
Hereโs What You Need:
| Ingredient | Swaps & Tips |
|---|---|
| Crisp rice cereal | Always use fresh cereal for best results. Stale cereal will make the bars taste off. |
| Unsalted butter | Salted butter works, just reduce the added salt. |
| Brown sugar | White sugar can be used, but flavor wonโt be as rich. |
| Heavy cream | Skip milk, it wonโt thicken the same. |
| Creamy peanut butter | Avoid natural peanut butter, it separates and wonโt set right. |
| Mini marshmallows | Use fresh for best melting and gooey texture. |
| Mini Reeseโs Cups | If you canโt find minis, chop Reeseโs Miniatures. |
| Chocolate chips | Semi-sweet balances sweetness, milk chocolate makes them sweeter. |
Quick Tip
If you canโt find Reeseโs Minis, chopped Reeseโs Miniatures (cut into quarters) work great.

Chelseaโs Recipe tip
My Top Peanut Butter Rice Krispie Treats Tips!
- Ingredients: Use fresh cereal and marshmallows for the best gooey treats.
- Watch the Heat: Donโt overcook the sugar mix, but donโt undercook it either. Too little boiling, and the treats wonโt set properly. Too much boiling and theyโll be hard.
- Mix Fast: Work quickly when mixing the cereal to keep it from cooling too much.
- Press Lightly: Gently press the mix into the pan to keep the bars soft.
- Clean Cuts: Use a sharp knife, warmed under hot water, and make firm cuts through the bars.
Storage
- Best Fresh: These peanut butter rice krispie treats taste best the first day theyโre made. Store in an airtight container at room temperature.
- Freezing: Cut, wrap, and freeze individual bars in a resealable bag for up to three months.

Equipment
- 9 x 9-inch baking pan
- Parchment paper or aluminum foil
Ingredients
- Cooking spray
- 5 cups rice krispies cereal like Rice Krispies
- 1/2 cup unsalted butter
- 3/4 cup light brown sugar packed
- 1/3 cup heavy cream
- 1/2 cup creamy peanut butter
- 2 cups miniature marshmallows
- 1/8 teaspoon salt
Optional Add-Ins
- 1 teaspoon vanilla extract
- 1/2 cup miniature marshmallows
- 3/4 cup Reeseโs minis see note 1
Topping
- 1-1/2 cups chocolate chips see note 2
- 2-1/2 tablespoons creamy peanut butter
Instructionsย
- Line aย 9ร9-inch panย with parchment paper (or foil), leaving an overhang for easy removal. Lightly spray with cooking spray. Set aside.
- In a very large pot over medium-high heat, melt the butter. Add the brown sugar and stir until fully dissolved, about 1โ2 minutes. Stir in the heavy cream, bring to a boil, and continue stirring constantly for 1 minute. Reduce heat to medium-low.
- Add in peanut butter, marshmallows, and salt. Stir until the marshmallows are melted. Remove from heat and stir in vanilla extract if using.
- Add the cereal to the pot and stir until fully coated. If using, stir in 1/2 cup marshmallows. Allow the mixture to cool slightly, then gently fold in the mini Reeseโs cups. Theyโll get pretty melty.
- Pour the mixture into the prepared pan. Lightly spritz your hands with cooking spray and gently press the cereal mixture into an even layer. Avoid pressing too hard to keep the bars from becoming too dense.
- In a small microwave-safe bowl, combine chocolate chips and peanut butter. Microwave in 15-second intervals, stirring in between, until melted and smooth. Spread the chocolate-peanut butter mixture evenly over the bars.
- Chill the bars in the fridge for 30 minutes to set the chocolate. Remove from the fridge, let them come to room temperature, cut into bars, and serve. To cut, use a sharp knife warmed under hot water and dried off, then make firm slices.

Recipe Notes
Note 1: Use unwrapped Reeseโs Minis (not miniatures).
Note 2: I prefer milk chocolate, but semi-sweet or dark chocolate can be used if you prefer a less sweet treat.
Tip: Donโt overcook the sugar mix, but donโt undercook it either. Too little boiling, and the treats wonโt set properly. Too much boiling and theyโll be hard.
Storage: These bars are best enjoyed the same day theyโre made. Store in an airtight container at room temperature. For freezing and thawing instructions, see the post.
