Ingredients

  • Oat flour: gives a hearty base and makes the cookies tender Choose finely milled oat flour for the best texture
  • Chocolate protein powder: boosts nutrition and brings chocolate flavor Look for a brand with minimal sugar and a flavor you already enjoy in shakes
  • Unsweetened cocoa powder: delivers rich chocolate taste Opt for Dutch-processed if you like deeper color and smoother flavor
  • Baking soda: helps the cookies rise and keep their chewiness Always check for freshness to avoid flat cookies
  • Salt: balances the sweetness and brings out the chocolate notes Use fine sea salt for even mixing
  • Coconut oil: keeps things moist and dairy free if you need it Choose a refined version for less coconut taste
  • Unsweetened applesauce: provides natural moisture and just a hint of fruitiness Organic or homemade works well here
  • Coconut sugar or brown sugar: offers gentle sweetness Look for coconut sugar with an even brown color and no lumps for easier creaming
  • Eggs: add structure and establish that classic chew Use room temperature eggs for easier mixing
  • Peppermint extract: is the heart of the holiday flavor Make sure it is pure peppermint not mint blend
  • Vanilla extract: smooths out the flavors and softens the peppermint edge Use real vanilla for a better finish
  • Dark chocolate chips: give bursts of melted chocolate throughout Try chopping up a favorite bar if you want larger pools
  • Crushed peppermint candies: make the tops pretty and deliver a sweet crunch Choose classic candy canes or round peppermints in bright white and red

Baking these was how I first convinced my youngest to try protein in baked goods She always asks for these when peppermint season comes around and insists on handing them out to friends

Storage Tips

Let cookies cool completely before storing This keeps them from going soggy inside Store in an airtight container at room temperature for up to five days If you are keeping them longer layer with parchment and freeze for up to two months Just thaw at room temp before eating For maximum freshness add a small piece of bread to the cookie container It helps absorb excess moisture and keeps cookies softer

Ingredient Substitutions

Need a vegan version Swap the eggs for flax eggs and use plant-based protein powder If nut allergies are a concern you can use avocado oil or melted butter instead of coconut oil Remember to check all your chocolate chips for allergens before using If oat flour is not available pulse rolled oats in a blender to create your own Just be sure to sift after blending for the best texture

Serving Suggestions

I love dipping these cookies in a mug of hot cocoa for an extra indulgent treat They are also great gifted in a festive tin or tucked into a lunchbox for a sweet pick-me-up Try serving them with vanilla ice cream or layering into a holiday dessert trifle with whipped cream

Cultural and Historical Context

Peppermint and chocolate is a holiday classic for a reason During the winter months candy canes and chocolate treats reign in American kitchens Protein cookies are a new spin turning something fun and seasonal into something you can feel good about enjoying even after the holidays
