Bailey’s Marshmallows

Is there anything better than Bailey’s in your hot cocoa or coffee? The answer is yes! These Bailey’s Marshmallows add that delicious Bailey’s flavor with that gooey marshmallow deliciousness! Homemade marshmallows are so much easier to make than you would ever think. Don’t be intimidated – I will walk you through the whole process and you’ll be blown away by how easy it is!

What you’ll need

If you have a stand mixer, you’ll want to use that.  If you only have a hand-held mixer, that’s okay too, just warm up your arm! You will also use a candy thermometer, but don’t worry, they’re super easy to use (and super inexpensive to buy)! I’ll walk you through the process below. Lastly, you’ll need an 8×8 pan and parchment paper, wax paper, or foil.

How to prepare your pan

Line a square 8×8 pan with parchment paper.  You can use binder clips to hold it in place! You’ll combine the corn starch and powdered sugar, and then spread about half of that around the bottom and up the sides of the parchment paper.

How to make Bailey’s Marshmallows

You’ll put the gelatin and Bailey’s in a mixing bowl, and set it aside.  Then you’ll want to heat all the rest of the ingredients on the stove, first covered for about 4 minutes, then uncovered until it reaches 240 F. This is where you’ll need the candy thermometer. Once you uncover the pot, all you have to do is clip the thermometer to the side of the pot, make sure the tip of the thermometer is in the mixture, but doesn’t touch the bottom of the pot. Then you let the thermometer do all the work! Once the thermometer reads 240 F, you’ll remove the pot from the heat, and carefully remove the thermometer from the pot (the thermometer could be hot to the touch).

Start running the mixer in the Bailey’s and gelatin. Slowly pour in the hot mixture, and then continue mixing for about 12 minutes, until the mixture is white and smooth.  Then, using a spatula that has been sprayed with non-stick spray, spread the marshmallow mixture into the prepared pan. You’ll then sprinkle the remaining corn starch/powdered sugar and then let set for a few hours.  Use a knife sprayed with non-stick spray to cut into squares, or you could even cut out shapes with a cookie cutter!

These are great to toss in a warm beverage, or just bite right in! These also make perfect homemade gifts!
