These keto St. Patrick's Day whoopie pies bring a soft cookie and a moist cake together in one festive treat, with rich chocolate mint flavor and a thick cream cheese filling. Made in one bowl with no chill time, they're an easy crowd-pleaser. Low carb, gluten-free, 3 net carbs and 11 grams of protein per pie.
Preheat oven to 350°F. Line a metal baking sheet (half sheet - 17.25 x 12.25 x 1 inches) with parchment paper.
Whisk the melted butter and granulated sweetener together in a medium bowl for about 30 seconds until well combined.
Mix in the eggs, vanilla, heavy cream, and food coloring until the mixture is smooth.
Add the protein powder, almond flour, and baking powder. Use a spatula to fold everything together until no dry streaks remain. Don't overmix. The batter should be thick, glossy, and hold its shape.
Using a 1.5-tablespoon cookie scoop, drop 12 mounds about 2-inches apart onto the prepared baking sheet. Cookies will spread slightly.
Bake for 9–11 minutes at 350°F. They are done when the tops feel springy and the edges are just barely golden.
Let the halves cool completely on the baking sheet for at least 10 minutes.
While cooling, beat the filling ingredients until fluffy. Spread, pipe, or cookie scoop onto the flat side of 6 halves, then press the other 6 on top. Enjoy!

Notes
Nutrition and carbs - Some nutrition labels omit sugar alcohols or allulose from the nutrition calculation since it does not affect blood sugar. For transparency, I have included all carbs and calculated the net carbs below. Always use a food logging app like Cronometer according to the brands you use in order to get accurate nutrition information. 27.43 Total Carbs – 1.87 Fiber – 22.71 Sugar Alcohols – 0 Allulose = 2.85 Net Carbs per pie (2 cookie halves with 1.5 tablespoon filling) or ⅙ of recipe.Link to original recipe before revision.
