Introduction

Peppermint is the flavor of the holidays. Maybe it’s because I’ve always loved candy canes growing up, but when I think about peppermint I think about Christmas!

So these are a soft sugar cookie with peppermint extract in the dough and crushed sugar-free peppermints pressed into the top of each one — the candy cane part is right there on the surface, where you can see it and bite through it. Nine cookies, and the only wait is half an hour in the freezer before you shape them.

Peppermint Flavor For Cookies

When making these cookies, you basically have two options when it comes to sourcing your peppermint flavor. You can go heavy on the sugar free store-bought peppermints, or you can add some keto friendly peppermint flavor.

Personally, we prefer to add some keto friendly peppermint flavor just because we don’t love the sweetener in the sugar free peppermints, but what you use is totally up to your personal preference.

We use Frontier’s peppermint flavor, and that is the one the card is written around. See the recipe below for how much of it goes in.

We love peppermint and are always looking for great ways to use it. If you’re like us and really love peppermint, make our Keto Chocolate Peppermint Shake! It is so delicious!

The card calls for two tablespoons of sugar-free peppermints, crushed, and it lists them as an ingredient rather than an optional one — the last step tops each cookie with the crumbs. So leaving them out is a change you are making to the recipe rather than a choice the card offers, and what goes with them is the crunch on top.

That is the trade, and it is yours to make. Plenty of people would rather not buy a bag of sugar-free candy to crush up, and the peppermint flavoring is doing the work in the dough either way.

Baking Good Tasting Keto Cookies

Keto cookies go wrong in a few predictable directions — tasting too much of almond flour, too sweet, soggy in the middle, or baked past soft into crisp.

We are not going to pretend one trick fixes all of that. What we can do is point at the three places on the card below where the decision is already settled for you.

The thirty minutes in the freezer come before the shaping, not after. The card gives the reason in the step itself: it makes the dough easier to handle. That is the one wait in this recipe, and it is there so you can form nine even rounds instead of fighting the bowl.

The bake window is two minutes wide. Ten to twelve minutes, and the endpoint the card gives is browned and cooked through — so watch the colour and start looking at ten rather than trusting the timer.

The sweetness is settled. Half a cup of powdered sweetener across nine cookies, with a teaspoon of vanilla and half a teaspoon of peppermint extract carrying the flavour. If these come out sweeter than you want, that is the number to change, and it is yours to change rather than ours to guess.

Best Keto Friendly Sweetener

For these keto peppermint cookies we used Lakanto’s powdered monk fruit — it is the powdered form the card is written around, and it is what we reach for in place of powdered sugar.

Lakanto’s blend is built to measure 1:1 with sugar — one cup of it where a regular recipe asks for one cup of sugar — and we don’t get the aftertaste or cooling effect some other keto-friendly sweeteners leave. The cooling one is worth noting here, since these cookies are already minty.

About these numbers: We are home cooks, not certified nutritionists. Nutrition is shared as a courtesy. We pick a representative product for each ingredient, and our recipe system works out the totals from the amounts in this recipe, so please treat them as a helpful estimate rather than a guarantee. The brands you buy, any swaps you make, and how generously you portion the recipe will all move these numbers.

Directions

  1. Preheat the oven to 350 degrees.

  2. Add all of the ingredients except for the peppermint candy crumbs to a mixing bowl, and blend on high until well combined.

  3. Place the batter into the freezer to set for 30 minutes. This will make the dough easier to handle.

  4. Form the dough into 9 even flattened cookies, and top each one with a sprinkling of the sugar-free peppermint candy crumbs.

  5. Bake for 10-12 minutes until browned and cooked through.

Updated — October 8, 2026: The section that listed ways a keto cookie goes wrong and then promised tips no longer promises tips we do not have to give.

Correction — October 8, 2026: The recipe card left the 30-minute freezer chill out of its times, so the total read 27 minutes for a recipe that needs closer to an hour. The times now count the chill.
