WANT TO SAVE THIS RECIPE?

Peppermint Sugar Cookie Bars bring that soft bakery-style cookie texture together with the cool, festive flavor of peppermint in a way that feels instantly cheerful. They are buttery, tender, and topped with a creamy frosting that turns a simple cookie bar into something worthy of a holiday tray, cookie swap, or cozy weekend baking session.

What makes these bars especially appealing is how easy they are to make compared to rolling and cutting individual cookies. You get all the charm of a classic Christmas sugar cookie with much less effort, plus a thick, satisfying bite that stays soft for days. Whether you are baking for a party or just want a sweet seasonal treat at home, these bars fit the moment beautifully.

Why You’ll Love This Peppermint Sugar Cookie Bars

These bars are perfect for anyone who loves a dessert that looks festive without asking for complicated steps. The cookie base bakes in one pan, the frosting spreads easily over the top, and a sprinkle of crushed peppermint candies adds color and crunch. The flavor is sweet and buttery with just enough peppermint to make it feel special without overwhelming the cookie itself.

Another reason these bars are such a favorite is how easy they are to serve. You can slice them neat and square for dessert platters, pack them into containers for gifting, or keep a batch in the fridge for those moments when you want something sweet with coffee or hot chocolate. They are simple, pretty, and always welcome.

Can I Use Peppermint Extract or Crushed Candy Canes?

Yes, and the best version often uses both. Peppermint extract gives the dough or frosting that smooth minty flavor throughout, while crushed candy canes add texture and a bright holiday finish on top. If you want a softer peppermint flavor, use a light hand with the extract and let the topping do most of the work. If you want a more pronounced mint taste, a little extract in the frosting goes a long way.

It also helps to keep balance in mind. Too much peppermint can overpower the buttery sugar cookie base, so a small amount is usually enough. The goal is a cookie bar that tastes festive and fresh while still keeping that classic sugar cookie warmth underneath.

Ingredients for the Peppermint Sugar Cookie Bars

The ingredients for these cookie bars are simple pantry staples with a few holiday touches that make the finished dessert feel extra special. Butter and sugar create the soft, rich base, while vanilla and peppermint bring in that familiar sweet bakery flavor with a seasonal twist. The frosting turns everything creamy and indulgent, and the crushed candy canes add the final sparkle.

Ingredients

• Unsalted butter keeps the bars rich, tender, and flavorful while giving the dough its soft texture.
• Granulated sugar sweetens the bars and helps create that classic sugar cookie taste.
• Eggs add structure and moisture so the bars bake up soft instead of dry.
• Vanilla extract rounds out the sweetness and deepens the cookie flavor.
• Peppermint extract gives the bars their signature cool mint flavor.
• All-purpose flour forms the body of the dough and creates a sturdy but tender crumb.
• Baking powder lifts the bars slightly so they stay light and soft.
• Salt balances the sweetness and sharpens the flavor of the butter and peppermint.
• Cream cheese makes the frosting smooth, slightly tangy, and extra creamy.
• Powdered sugar sweetens the frosting and helps it spread beautifully.
• Milk or heavy cream loosens the frosting to the right consistency.
• Crushed candy canes or peppermint candies add crunch, color, and a festive finish.
• Holiday sprinkles are optional, but they make the bars look even more playful and party-ready.

How To Make the Peppermint Sugar Cookie Bars

Making these bars is much easier than shaping individual cookies, which is one of the reasons they are so useful during a busy baking season. Once the dough is mixed, it gets pressed into a pan, baked until just set, then topped with frosting after cooling. The final sprinkle of peppermint makes them look as festive as they taste.

Step 1: Prepare the Pan and Oven

Preheat your oven to 350°F and line a 9×13-inch baking pan with parchment paper or lightly grease it. This helps the bars release easily and makes cleanup much simpler once they are sliced.

Step 2: Cream the Butter and Sugar

In a large mixing bowl, beat the softened butter and granulated sugar until the mixture looks light and fluffy. This step builds the base texture, so give it a few minutes to fully combine and aerate.

Step 3: Add the Wet Ingredients

Mix in the eggs one at a time, then add the vanilla extract and peppermint extract. Stir until everything is fully blended and smooth.

Step 4: Add the Dry Ingredients

In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry mixture to the wet ingredients, mixing just until a soft dough forms. Do not overmix, or the bars can turn dense instead of tender.

Step 5: Press and Bake

Transfer the dough to the prepared pan and press it into an even layer. Bake for 18 to 24 minutes, or until the edges are lightly golden and the center looks set. Avoid overbaking if you want that soft sugar cookie texture.

Step 6: Cool Completely

Let the bars cool fully in the pan before adding frosting. If the bars are still warm, the frosting will melt and lose its smooth finish.

Step 7: Make the Frosting

Beat the cream cheese until smooth, then add the powdered sugar and a splash of milk or cream. Mix until creamy and spreadable. For more peppermint flavor, add a tiny drop of peppermint extract.

Step 8: Frost and Decorate

Spread the frosting over the cooled bars in an even layer. Top with crushed candy canes and holiday sprinkles if using. Chill briefly if you want cleaner slices, then cut into squares and serve.

Serving and Storing Peppermint Sugar Cookie Bars

These bars are rich enough to feel like a special dessert, but easy enough to serve casually with coffee, cocoa, or a glass of milk. A 9×13-inch pan usually feeds about 16 people if you cut medium squares, though you can make smaller pieces for party platters and holiday dessert trays.

To store them, keep the bars in an airtight container in the refrigerator if they are frosted with cream cheese frosting. They stay fresh for about 4 to 5 days and taste wonderful cold or slightly softened at room temperature. You can also freeze the unfrosted bars, then thaw and decorate when needed.
