Heat up the half & half cream in a small pot over medium heat.
As soon as the bubbles will start forming around the edges of the pot, add the marshmallows and whisk until they fully melt into the cream.Make sure to whisk as otherwise the cream will foam and bubble out of the pot.
Add the peppermint extract and whisk again.
Make Peppermint Whipping Cream
Whip the cold heavy whipping cream until it starts to thicken.
Add the icing sugar and peppermint extract and keep whipping until it's thick and luscious and at your desired consistency (soft peaks, medium peaks, or hard peaks).
Make Peppermint Marshmallow Latte
Pour half the hot Peppermint Creamer into each cup of hot Nespresso coffee.
Top with the desired amount of Peppermint Whipped Cream.
Sprinkle crushed candy canes and garnish with a whole candy cane.
Peppermint creamer will get a bit lumpy if it's stored in the fridge, so heat it up and stir before serving.
This amount of whipped cream makes enough for about 4 servings of peppermint latte.
