Homemade peanut butter marshmallows are so much fun! This peanut butter marshmallow recipe makes marshmallows that are gorgeous, silky smooth, and impossibly soft. They are huge, fluffy, and dreamy. These aren't peanut butter flavored marshmallows using a flavor - they are actually filled with peanut butter. They are apart of my "cookies turned into marshmallows" mini series, where I've taken the top five American cookies and re-imagined them as marshmallows.
These are pillowy clouds of marshmallow goodness, layered with velvety smooth peanut butter.
Are marshmallows easy to make?
Yes. Marshmallow are easy to make, especially for the home baker, since most home bakers already have all of the ingredients and equipment needed to make homemade marshmallows. Homemade marshmallows are easier than you think to make and the results are so WORTH IT! Bouncy and full of flavor, they blow store bought marshmallows away.
What is in homemade marshmallows?
Marshmallows have a long history! Modern marshmallows are made of: sugar, a syrup (corn, glucose, tapioca, etc), gelatin, and flavoring. Some marshmallows are made using egg whites to incorporate air while others are made using gelatin. A few marshmallow recipes will call for both!
- unflavored gelatin
- white sugar
- corn syrup
- peanut butter powder: powdered peanut butter is defatted peanut butter, which allows the marshmallow to retain the fluffy, aerated, texture.
- creamy peanut butter: Swirl into the very top of the marshmallows
- confectioners sugar: for dusting marshmallows after cutting

Marshmallow set up time
Marshmallows need plenty of time to dry out and set at room temperature. 12 hours or overnight is ideal - prior to cutting. Do not put these in the fridge because it causes the mixture to deflate and the sugar structure of the marshmallows to change.
Store marshmallows in an air tight container at room temperature to maintain their softness and texture.
Marshmallows will stay fresh for about a month.
I've tested A LOT of unflavored gelatins and the Great Value Unflavored Gelatin is my favorite by a mile. It is truly unflavored without that typical gelatin scent.
Yes. You need to measure the end temperature for cooking marshmallows and the cooling syrup temperatures. For example, if your end temperature is too low, you will make marshmallow fluff. Consequently, if your end temperature is too high, your marshmallows will be tough and not fluffy. If your cooling syrup is too hot, the marshmallows will not set up correctly. However if your cooling syrup is too cold, it will turn into a hard block in your mixer and not whip.
Yes, home made marshmallows are gluten free. However, the equipment used to make marshmallows is also used to make items containing gluten so cross contamination may be an issue. Please make sure to check with your marshmallow maker for information on their particular recipe and kitchen.
Homemade marshmallows will stay good for approximately one month at room temperature and stored in an airtight container.
No. Do not refrigerate homemade marshmallows because it causes changes to the texture.
Sticky marshmallows can be from wrong final cooking temperatures or improper storage. Coating the marshmallows in powdered sugar reduces stickiness from where they were cut with a knife.
