These Peppermint Sugar Cookie Bars are the ultimate festive treat, combining a thick, soft, pale blonde sugar cookie base with a cloud-like layer of peppermint buttercream. If you are looking for the perfect holiday dessert to stop the scroll on Pinterest, these bars—topped with iconic red and white striped Candy Cane Kiss chocolates and crushed candy canes—are the answer.
The beauty of the Peppermint Sugar Cookie Bars lies in their texture. Unlike traditional crispy cookies, these bars are dense, chewy, and melt-in-your-mouth soft, much like a gourmet pink coconut snowball cake bars experience in cookie form. Every bite delivers a burst of cool peppermint and buttery sweetness that screams Christmas morning.

Essential Ingredients for the Perfect Peppermint Sugar Cookie Bars
To achieve that signature professional bakery finish, you need specific ingredients that ensure the Peppermint Sugar Cookie Bars remain soft rather than crunchy. Much like our strawberry cheesecake cookies, the secret is in the moisture balance.
Unsalted Butter (1 cup / 226g): Ensure your butter is softened to room temperature. This allows for proper aeration during the creaming process, creating a light yet dense base.
Granulated Sugar (1.5 cups / 300g): Pure sweetness that provides the structural foundation for the sugar cookie crumb.
Large Eggs (2): These act as the binder. Using room-temperature eggs ensures they emulsify perfectly with the creamed butter and sugar.
Peppermint & Vanilla Extracts (1 tsp each / 5ml): The vanilla rounds out the flavor, while the peppermint extract provides that classic holiday “chill.”
All-Purpose Flour (2.5 cups / 312g): The structural backbone. Weigh your flour if possible to avoid a dry, crumbly bar.
Cornstarch (2 tsp): The “secret ingredient” that keeps the sugar cookie base ultra-soft and prevents it from getting too tough.
Baking Powder (1 tsp) & Salt (1/2 tsp): Essential for a slight lift and to balance the intense sweetness of the frosting.
Peppermint Buttercream: A combination of butter, powdered sugar, heavy cream, and more peppermint extract creates a thick, opaque white layer of frosting.
The Toppings: You will need 24 Candy Cane Kiss chocolates (stripped red and white) and 1/4 cup (30g) of finely crushed red and white candy canes for that final crunchy garnish.
Step-by-Step Instructions for Holiday Success
1. Preparing the Soft Sugar Cookie Base
Preheat your oven to 350°F (175°C). Line a 9×13 inch (23x33cm) baking pan with parchment paper, leaving an overhang on the sides. This makes it easy to lift the Peppermint Sugar Cookie Bars out for clean slicing later.
In a large bowl, cream together the softened butter and granulated sugar for at least 3-4 minutes. You are looking for a pale, fluffy texture. Add the eggs one at a time, followed by the peppermint and vanilla extracts. Visual Cue: The mixture should look like a smooth, pale yellow custard.
Whisk the dry ingredients together in a separate bowl. Gradually add them to the wet ingredients. Do not overmix! Mix just until the white streaks of flour disappear. The dough will be thick and slightly tacky.
2. The “Pale Blonde” Bake
Press the dough evenly into your prepared pan. Use the bottom of a measuring cup to smooth the top. Bake for 18-22 minutes. Visual Cue: The edges should be set, but the top must remain a pale blonde color. Do not let the bars brown, or they will lose their signature softness.
Allow the base to cool completely in the pan. If you frost a warm cookie bar, your beautiful peppermint buttercream will melt into a puddle. For best results, chill the base in the fridge for 30 minutes before frosting.
3. Whipping the Opaque White Peppermint Frosting
While the bars cool, prepare the frosting. Beat softened butter until smooth. Add powdered sugar one cup at a time, alternating with splashes of heavy cream. Add the peppermint extract last.
Whip the frosting on high speed for 2 minutes until it is bright white and holds a stiff peak. This ensures the Peppermint Sugar Cookie Bars have that “generous, smooth layer” of frosting seen in our visual blueprint.
4. Decorating for Maximum Pinterest Appeal
Spread the frosting over the cooled bars using an offset spatula. Ensure the layer is thick and even from edge to edge. Use a sharp knife to cut the bars into 24 squares.
Visual Cue: In the center of each square, gently press one red and white striped Candy Cane Kiss. Finally, scatter the finely crushed red and white candy cane pieces across the top. The contrast against the white frosting creates a bright, clean holiday aesthetic.
Expert Tips for the Best Peppermint Sugar Cookie Bars
- Room Temp Ingredients: Always use room temperature butter and eggs to prevent the batter from curdling.
- Don’t Overbake: This is the most common mistake. The bars will continue to firm up as they cool. If they look “done” in the middle, they are overbaked.
- Clean Slices: For those perfect square cuts, wipe your knife with a warm, damp cloth between every single cut.
- Crushing Candy Canes: Place candy canes in a Ziploc bag and use a rolling pin. Aim for a mix of “dust” and small crunchy pieces for texture.
Storage, Reheating & Freezing
Storage: These bars stay fresh in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the fridge for up to a week.
Freezing: You can freeze the baked (unfrosted) base for up to 3 months. If freezing frosted bars, flash-freeze them on a tray first so the Candy Cane Kisses don’t get squashed, then wrap them tightly.
Pro Tip: If you enjoy a savory treat after your sweets, these bars pair surprisingly well after a meal of sourdough discard flatbread or a cozy bowl of easy chicken tortilla soup.
What to Serve With These Bars
These Peppermint Sugar Cookie Bars are the star of the show, but they love company! Serve them alongside a hot cocoa bar or a steaming mug of peppermint tea. If you are hosting a holiday party, they look stunning on a platter next to apple pie egg rolls for a variety of festive textures.
Frequently Asked Questions
Peppermint oil is much stronger than extract. If substituting, use only 1/4 of the amount called for in the recipe to avoid an overpowering medicinal taste.
While not strictly required, cornstarch is the secret to a ‘melt-in-your-mouth’ texture. It softens the flour’s proteins, resulting in a finer, softer crumb.
Press the chocolates into the frosting immediately after slicing the bars while the frosting is still slightly tacky. This creates a secure bond as the frosting sets.
The most likely cause is overbaking. The bars should be pulled from the oven when they are still pale blonde and look slightly underdone in the center.
