These aren’t just any blondies; they are a celebration of holiday flavors, crafted to be both easy to make and utterly irresistible.
The Star Ingredient: Hershey’s Peppermint Kisses
At the heart of these sensational peppermint blondies lies a true holiday gem: Hershey’s Peppermint Kisses. These delightful little confections are a seasonal favorite, typically gracing store shelves throughout the holiday period. They embody the perfect marriage of creamy white chocolate and crisp, cool peppermint, providing both a wonderful flavor and an appealing texture to our blondies. Using them ensures that distinct, authentic peppermint taste that everyone associates with Christmas treats.
Blondies have always held a special place in the world of home baking. Their unique charm comes from that deep, buttery, caramelized brown sugar flavor that makes them utterly “to-die-for.” What’s more, they are incredibly forgiving and wonderfully simple to prepare. Forget the stand mixer or complex techniques; all you truly need are a couple of mixing bowls and a sturdy wooden spoon or rubber spatula. This makes them an ideal choice for bakers of all skill levels, especially during the busy holiday season when time is precious.

Essential Tips for Baking Perfect Peppermint Blondies with Buttercream
Achieving bakery-quality blondies at home is surprisingly simple with a few smart techniques. Here are some invaluable tips to ensure your Peppermint Blondies turn out incredibly delicious and picture-perfect every time:
- Unwrapping the Kisses: A Fun Family Activity. You’ll need a good number of Hershey’s Peppermint Kisses for this recipe, which means quite a bit of unwrapping! This can actually be a delightful, simple task for children, turning recipe prep into a fun family activity. Gather the little helpers, put on some festive music, and make it a pre-baking party!
- Effortless Removal with Parchment Paper. To ensure your blondies lift cleanly out of the pan without any sticking or breaking, always line your baking pan with parchment paper. Leave a slight overhang on the sides – these “handles” will allow you to easily lift the entire slab of cooled blondies out of the pan. If parchment paper isn’t available, aluminum foil can be used in a pinch, though parchment offers a superior non-stick surface. Once completely cooled, simply lift the blondies by the parchment paper, transfer them to a cutting board, and slice into perfect squares.
- Cooling is Key for Perfect Slices. Patience is a virtue, especially in baking! Resist the urge to cut and frost your blondies while they are still warm. Warm blondies are prone to crumbling and will melt the delicate buttercream. Allow them to cool completely in the pan before lifting and cutting. For an even quicker cool-down, you can place the pan in the refrigerator for about 30-60 minutes after it has reached room temperature.
- Accurate Ingredient Measurement. Baking is a science, so precise measurements are crucial. Use a kitchen scale for flour if possible, or use the “spoon and level” method: spoon flour into your measuring cup and then level it off with a straight edge. This prevents overly dense blondies.
- Don’t Overmix. Once you combine the wet and dry ingredients, mix just until no streaks of flour remain. Overmixing can develop the gluten in the flour, leading to tough blondies rather than soft and chewy ones.
Optimal Storage for Long-Lasting Freshness
Proper storage is essential to keep your frosted Peppermint Blondies tasting fresh and delicious for days. Once frosted, these delightful treats can be stored in an airtight container for 3 to 4 days. You have the flexibility to store them either in the refrigerator or at room temperature, depending on your preference and climate. Storing them in the fridge can extend their shelf life slightly and keep the buttercream firmer, especially in warmer environments. Always ensure the container is airtight to prevent them from drying out or absorbing other odors from your fridge. For longer storage, unfrosted blondies can be frozen for up to 3 months, then thawed and frosted when ready to serve.

Prep Time: 20 mins
Cook Time: 25 mins
Servings: 24

Ingredients
For the Peppermint Blondies:
- 1 cup unsalted butter, melted
- 1 1/4 cups packed light brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 1 large egg yolk
- 2 teaspoons vanilla extract
- 2 1/2 cups all-purpose flour
- 1 teaspoon salt
- 1/2 teaspoon baking powder
- 1 1/2 cups chopped Hershey’s Peppermint Kisses
For the Peppermint Buttercream:
- 1/4 cup unsalted butter, softened
- 2 1/2 cups powdered sugar
- 1 tablespoon milk
- 1/2 teaspoon peppermint extract
- 1/2 cup chopped Hershey’s Peppermint Kisses (for garnish/texture)
Instructions
- Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, allowing some overhang on the sides for easy removal.
- In a large mixing bowl, combine the melted unsalted butter, packed light brown sugar, and granulated sugar. Stir until well combined and smooth.
- Beat in the eggs, additional egg yolk, and vanilla extract until the mixture is light and creamy.
- In a separate medium bowl, whisk together the all-purpose flour, salt, and baking powder until thoroughly combined.
- Gradually add the dry ingredients to the wet ingredients, stirring gently with a wooden spoon or spatula until just combined. Be careful not to overmix.
- Fold in the 1 1/2 cups of chopped Hershey’s Peppermint Kisses, distributing them evenly throughout the batter.
- Spread the blondie batter evenly into the prepared baking pan.
- Bake for 25 to 30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with moist crumbs, but not wet batter.
- Allow the blondies to cool completely in the pan on a wire rack before attempting to frost them. This is crucial for clean cuts and to prevent the frosting from melting.
- While the blondies cool, prepare the peppermint buttercream: In a medium bowl, using an electric mixer (handheld or stand mixer), beat the softened unsalted butter until creamy. Gradually add the powdered sugar, milk, and peppermint extract. Beat on medium speed until the frosting is smooth, light, and fluffy.
- Gently stir in the remaining 1/2 cup of chopped Hershey’s Peppermint Kisses into the buttercream for extra texture and flavor.
- Once the blondies are completely cool, use the parchment paper overhangs to lift them out of the pan and transfer them to a cutting board.
- Spread the prepared peppermint buttercream evenly over the cooled blondies.
- Cut the blondies into 24 squares (or your desired size) and serve immediately, or store as directed.
