These buttery keto cookies are infused with refreshing peppermint and feature swirls of rich sugar-free dark chocolate, creating a delightful flavor combination perfect for a cozy evening. Made with almond and coconut flours, they offer a low-carb, gluten-free treat that melts in your mouth. Easy to prepare and bake, these cookies balance sweetness with a cool peppermint twist, making them ideal for relaxing nights without compromise.
There's something about a quiet evening that makes you crave something sweet but sensible. I was sitting at my kitchen table on a chilly November night, halfway through a mug of peppermint tea, when I realized I wanted a cookie that didn't require me to abandon my low-carb goals. That's when these peppermint twist cookies came into being—buttery, rich, and entirely judgment-free.
I made a batch for my sister on one of those winter evenings when we needed an excuse to sit together with tea and talk. She bit into one, paused, and just said, "These taste like you figured something out." That's exactly what they are—proof that keto desserts don't have to feel like compromise.
Ingredients
- Almond flour: The foundation that keeps these cookies tender without gluten; make sure yours is finely ground or they'll feel gritty.
- Coconut flour: Adds structure and a subtle sweetness that balances the peppermint without announcing itself.
- Powdered erythritol: Dissolves smoothly into the dough, avoiding that gritty texture you get with granulated sweeteners.
- Baking powder: Just a whisper to help them rise slightly and bake evenly.
- Salt: Quiets the sweetness and deepens every other flavor.
- Unsalted butter: Softened butter creams better than cold butter, creating that melt-in-your-mouth texture.
- Egg: Binds everything together and adds richness; room temperature works best.
- Vanilla and peppermint extracts: A teaspoon of peppermint is the sweet spot; more will overpower everything, and you'll taste nothing else.
- Sugar-free dark chocolate chips: Choose ones you'd actually eat on their own, because they matter.
- Coconut oil: Loosens the chocolate just enough to drizzle without making it thin and runny.
- Crushed sugar-free peppermint candies: The optional garnish that turns a good cookie into one you remember.
Instructions
- Set yourself up:
- Preheat your oven to 350°F and line a baking sheet with parchment paper. This takes two minutes and saves you from cookies sticking to the pan like they've put down roots.
- Build the dry base:
- Whisk almond flour, coconut flour, erythritol, baking powder, and salt in a medium bowl until they're evenly combined. You're looking for no lumps of sweetener hiding anywhere.
- Cream the wet ingredients:
- Beat softened butter with the egg, vanilla, and peppermint extract until the mixture is pale and fluffy, about two minutes. This is where the magic of texture begins.
- Bring it together:
- Gradually add your dry mixture to the wet one, stirring until a soft dough forms. Don't overmix; once you see no white streaks, you're done.
- Melt the chocolate gently:
- Combine chocolate chips and coconut oil in a microwave-safe bowl, then heat in 20-second bursts, stirring between each one. Microwaves are aggressive, and chocolate burns faster than you'd think.
- Create the swirl:
- Drizzle melted chocolate over the dough and swirl gently with a spatula—think marble, not complete chaos. The key is restraint; a few streaks look intentional and beautiful.
- Portion and prepare:
- Scoop tablespoon-sized portions onto your prepared sheet, leaving about two inches between each cookie. If you want, sprinkle crushed peppermint candies on top now.
- Bake with attention:
- Bake for 12 to 15 minutes, checking around the 12-minute mark. You want the edges golden but the centers still soft; they'll firm up as they cool.
- Cool properly:
- Let them sit on the baking sheet for 10 minutes before transferring to a wire rack. This patience prevents them from falling apart and gives them structure.
One morning, I reached into a container of these cookies, grabbed one cold from the fridge, and it tasted even better than fresh—the peppermint had deepened overnight, the chocolate felt more luxurious. That's when I realized these weren't just a low-carb trick; they were actually good.
Why These Work for Keto
Almond flour and coconut flour are the secret weapons of keto baking because they mimic the texture of regular flour while keeping carbs laughably low. Erythritol dissolves completely into the dough instead of leaving that scratchy feeling you get with some sugar alcohols. The fat from butter and the egg yolk creates that tender crumb that makes you forget you're eating something "diet-friendly."
The Peppermint-Chocolate Pairing
Peppermint and chocolate are a classic combination for a reason—the cool brightness of peppermint cuts through rich chocolate's heaviness and makes your mouth feel alive. When you add that combination to a buttery cookie, it becomes something that tastes like indulgence. The chocolate swirl isn't just decoration; it's there to remind you with every bite that this is special.
Storage and Serving Ideas
These cookies keep well in an airtight container for up to five days, though honestly, they rarely last that long in a house where someone knows they exist. They pair beautifully with herbal tea on an evening when you need to wind down, or with unsweetened hot chocolate if you want to lean into the cozy factor completely. Serve them slightly cold from the fridge if you want maximum texture contrast.
- Pair them with peppermint tea for a moment that feels completely intentional and rewarding.
- Store them separately from other cookies or their peppermint flavor will drift into everything else.
- If someone asks what diet you're on while eating these, just hand them one instead of explaining.
These cookies prove that eating keto doesn't mean missing out on the small pleasures that make an evening feel special. Bake them when you want proof that comfort and conscience can coexist on the same plate.
