It has been cold and snowy here in New York City, and I find myself craving peppermint sweets. This peppermint swirl protein fudge is the perfect chewy, chocolatey peppermint treat!
I started with my double chocolate protein fudge recipe, but doubled it. To make the peppermint swirl, I mixed some unflavored whey protein powder with a little coconut flour, raw agave, water, and peppermint flavoring. A delicious combination!

I think it is important to use alcohol-free peppermint flavoring here, since this isn't a cooked recipe. Extracts containing alcohol really upset the natural flavors, in my opinion.
After putting the chocolate batter in a lined pan, I spooned the peppermint batter on top and swirled it with a butter knife. Because this was a larger pan of fudge, it needed several hours in the freezer to set.
And it was certainly worth the wait! Peppermint swirl protein fudge, my new winter favorite!

I was thinking whey, too. :)
I'm glad you are enjoying the recipes!

If it can be created with whey I would be so thankful! Your website is so helpful!

Hi Mii,
I'm pretty sure if you baked this it would turn into something rubbery. Whey doesn't bake well unless it is mixed with enough other ingredients. It sounds like you want a peppermint swirl brownie, which is a great idea! I'll put that on my list. :)
