Birthday Marshmallows

Recipes » Candies » Birthday Marshmallows

Marshmallows from scratch have become my favorite thing to make these days. They are surprisingly easy to make and homemade marshmallows are just so much better than store-bought marshmallows. I actually don’t really like eating marshmallows from a bag unless they are toasted, but homemade marshmallows are so good that I eat them right out of the pan! This birthday marshmallows recipe comes together in about 30 minutes with very little work, and then it’s just a matter of patience waiting for them to set!

Why this recipe works

These birthday cake marshmallows are loaded with sprinkles! A marshmallow works so well with a vanilla flavor, and the sprinkles add such a fun pop of color to make them perfect party treats! They’re essentially a funfetti cake marshmallow! You can never have too many sprinkles!

Ingredients and notes

Gelatin – Gelatin gives the marshmallows their shape and structure. This does unfortunately mean these marshmallows are not vegan, though I have heard that agar agar makes a good substitute. I have not tested it in this recipe, but if you try it, please let me know how it goes!

Corn Syrup – Corn syrup makes the marshmallows stickey and gooey. It also contributes to the sweetness. You can lessen the corn syrup for a lighter, fluffier marshmallow, or use the amount in the recipe for a gooey marshmallow.

Sprinkles! – Sprinkles are, of course, key in this easy homemade marshmallows recipe. It’s not a celebration without sprinkles!

Increase the mixer to high speed (do this slowly to avoid splatter!) and beat for another 10 minutes.

Recipe FAQs

What kinds of desserts can you make with marshmallows?

The options for baking with marshmallows are endless! There are also lots of fun activities with marshmallows, like chubby bunny, if you’re in need of marshmallow birthday party ideas!

Can you roast homemade marshmallows?

It depends on the recipe. I would be cautious roasting these birthday marshmallows because the sprinkles on the outside may burn.

What is the best way to store marshmallows?

Marshmallows should be stored at room temperature in an airtight container. They should stay good for at least 3 weeks if stored properly.

Tips & Tricks

  • Use a 9×13 pan for smaller marshmallows. The 8×8 pan makes super thick mallows!
  • Non-pareils or sugar crystal sprinkles will work best for this coating, but any sprinkles will do!
  • Once adding the sprinkles to the marshmallow filling, you’ll want to stir just enough to disburse them evenly, but if you stir too much, the sprinkles will melt into the filling.
  • Bigger sprinkles such as jimmies will work best for the filling sprinkles. They’ll be more noticeable in the middle of the marshmallow than smaller sprinkles like nonpareils.
