Essential Ingredients for Your Peppermint Sugar Cookie Bars
To achieve that specific bakery-style texture, we need a balance of high-quality fats and precise leavening. Here is what you will need for these Peppermint Sugar Cookie Bars:
The Soft-Baked Cookie Base
- 1 cup (227g) Unsalted Butter: Ensure your butter is softened to room temperature for a smooth emulsion with the sugar.
- 1 ½ cups (300g) Granulated Sugar: Provides sweetness and helps create those slightly crisp, pale golden edges.
- 2 large Eggs: Act as the primary binding agent, contributing to the dense, moist crumb.
- 1 tablespoon (15ml) Vanilla Extract: Use a high-quality extract to ground the bright peppermint notes.
- 3 cups (375g) All-Purpose Flour: The structural foundation of the bar. Measure by weight for the best results.
- 1 teaspoon (5g) Baking Powder: Provides just enough lift to keep the bars from being overly heavy.
- ½ teaspoon (3g) Fine Sea Salt: Essential for balancing the sweetness of the frosting.
The Peppermint Frosting and Toppings
- ½ cup (113g) Unsalted Butter: Softened for a spreadable, matte finish.
- 3 cups (360g) Powdered Sugar: Sifted to ensure a completely smooth buttercream.
- 2-3 tablespoons (30-45ml) Heavy Cream: Adjust the amount to achieve a thick, even layer of frosting.
- ½ teaspoon (2.5ml) Peppermint Extract: Adds that signature holiday cooling sensation without being overpowering.
- 16 Red and White Striped Peppermint Kisses: Pressed into the center for a professional visual finish.
- ¼ cup (40g) Crushed Candy Canes: Fine shards provide a necessary textural crunch.

Step-by-Step Instructions for Perfect Cookie Bars
1. Prepare the Pan and Cream the Butter
Preheat your oven to 350°F (175°C). Line a 9×9 inch (23x23cm) square baking pan with parchment paper, leaving an overhang on the sides for easy removal. In a large bowl, cream together the 1 cup (227g) softened butter and 1 ½ cups (300g) granulated sugar for 3-5 minutes until the mixture is light, pale, and fluffy.
2. Incorporate the Wet Ingredients
Add the 2 large eggs one at a time, beating well after each addition. Mix in the 1 tablespoon (15ml) vanilla extract. This ensures the Peppermint Sugar Cookie Bars have a deep, complex flavor profile that supports the peppermint topping.
3. Mix the Dry Ingredients and Bake
In a separate bowl, whisk the 3 cups (375g) flour, 1 teaspoon (5g) baking powder, and ½ teaspoon (3g) salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined. The dough should be thick and slightly tacky. Press the dough evenly into the prepared pan. Bake for 20-25 minutes until the edges are just barely golden, but the center remains pale. Crucial Cue: Do not over-bake! The bars will continue to firm up as they cool.
4. Whip the Matte Peppermint Frosting
While the base cools completely, prepare the frosting. Beat the ½ cup (113g) butter until smooth. Gradually add the 3 cups (360g) powdered sugar, peppermint extract, and heavy cream. Whip on high until the frosting is matte, white, and holds its shape. It should look like fresh snow.
5. Decorate for Pinterest Success
Spread the frosting in a thick, even layer over the cooled cookie base. Use a ruler to lightly mark 16 even squares. Press one striped peppermint kiss into the center of each square. Finish by sprinkling the crushed candy cane shards across the entire surface. Slice into squares and enjoy the handheld perfection.
Expert Tips for the Best Peppermint Sugar Cookie Bars
- Temperature Control: Ensure the cookie base is 100% cool before frosting, otherwise the matte buttercream will melt and lose its texture.
- Clean Cuts: For those sharp, Pinterest-ready edges, chill the frosted bars for 30 minutes before slicing with a hot, dry knife.
- Measure Flour Correctly: Use a kitchen scale. Too much flour will result in a dry, crumbly bar instead of the dense, moist crumb we want.
- Candy Cane Timing: Add the crushed candy canes just before serving to prevent the red dye from bleeding into the white frosting.

Storage and Freezing Instructions
Store your Peppermint Sugar Cookie Bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. If refrigerating, let them sit at room temperature for 20 minutes before serving to soften the buttercream.
To Freeze: You can freeze the unfrosted cookie base for up to 3 months. If freezing decorated bars, flash-freeze them on a tray for an hour before wrapping them individually in plastic wrap to preserve the peppermint kiss and frosting shape.
What to Serve with Peppermint Cookie Bars
These bars are incredibly rich, so they pair best with beverages that cut through the sweetness. A steaming mug of black coffee or a cold glass of whole milk is traditional. For a festive party, serve them alongside a hot cocoa bar.

Frequently Asked Questions
Absolutely. You can bake the base 2 days in advance. Once frosted, they stay fresh for up to 3 days at room temperature or 5 days in the fridge.
Yes, but be very careful. Peppermint oil is much more concentrated than extract. Use only 1-2 drops for the frosting to avoid an overpowering medicinal taste.
No! This recipe is designed for ease. Since you are pressing it into a pan rather than cutting out shapes, there is no need to chill the dough.
The secret is under-baking. Pull them out when the edges are set but the center still looks slightly pale. They will firm up as they cool to create that perfect moist crumb.
Candy canes are made of sugar and will eventually draw moisture from the frosting. For the best visual results, sprinkle the crushed candy canes immediately before serving.
