Gluten Free Peanut Butter Marshmallow (Printable)
No-bake gluten-free peanut butter and marshmallow squares—chewy, creamy, chilled until set and served cold.
# What You Need:
→ Base
01 - 1 cup creamy peanut butter (verified gluten-free)
02 - 1/2 cup unsalted butter
03 - 1 1/2 cups gluten-free powdered sugar
04 - 1 teaspoon pure vanilla extract
→ Mix-Ins
05 - 3 cups mini marshmallows (certified gluten-free)
→ Optional Topping
06 - 1/2 cup gluten-free chocolate chips
# How-To:
01 - Line an 8x8-inch baking pan with parchment paper, leaving enough overhang on the sides to lift the finished treat out easily.
02 - In a medium saucepan over low heat, combine the creamy peanut butter and unsalted butter. Stir continuously until fully melted and smooth.
03 - Remove the saucepan from heat. Add the gluten-free powdered sugar and pure vanilla extract, stirring vigorously until the mixture is completely smooth and well combined.
04 - Allow the mixture to cool for 2 to 3 minutes so it is warm but not hot. Gently fold in the mini marshmallows, coating them evenly without melting them completely.
05 - Pour the marshmallow mixture into the prepared baking pan. Use a spatula to press it into an even, uniform layer.
06 - If using, sprinkle the gluten-free chocolate chips evenly across the surface and lightly press them into the mixture so they adhere.
07 - Refrigerate the pan for at least 1 hour, or until the mixture is firm and fully set.
08 - Lift the treat out of the pan using the parchment paper overhang. Cut into 16 even squares and serve chilled.
# Expert Tips:
01 -
- No oven required, which means you can make these even when your kitchen feels like a sauna in summer.
- The contrast between gooey marshmallows and rich peanut butter is the kind of combination that disappears from the pan before it fully sets.
02 -
- If you fold in the marshmallows while the mixture is too hot they will dissolve into goo, so that brief cooling pause really matters.
- Wet your fingers or the back of a spoon with a little water before pressing the mixture into the pan to keep it from sticking to your hands.
03 -
- Stir the peanut butter and butter constantly over low heat to avoid scorching the bottom of the pan.
- A pinch of flaky sea salt on top is the simplest upgrade that makes people ask what your secret is.
