Ingredients

  • Unsalted butter at room temperature: contributes to a tender cake like texture Make sure it is very soft for smooth mixing
  • Sugar: for sweetness and that classic sugar cookie base opt for fine granulated sugar for a lighter crumb
  • Large egg: adds moisture and richness select fresh eggs with bright yolks
  • Vanilla extract: brings warmth to balance the peppermint Choose pure vanilla for best results
  • All purpose flour: for structure Ensure it is fresh and measured accurately to avoid dry bars
  • Baking powder: gives the bars lift Freshness matters for fluffiness
  • Salt: accentuates flavors Use fine sea salt for better distribution
  • Crushed peppermint candy: provides crunch and a bright cool flavor Use candy canes or boxed peppermint bits and check for freshness to avoid stickiness
  • Powdered sugar for the frosting: creates that fluffy topping Choose pure cane sugar for smoothness
  • Milk or heavy cream: gives creamy richness to the frosting Pick whole milk or cream for extra lusciousness
  • Optional cream cheese or white chocolate: for extra richness in the frosting Select quality additions for a gourmet touch

Instructions

Prep the Pan:
Line a nine inch square baking pan with parchment paper and spray lightly with nonstick spray This helps lift the bars out cleanly once baked
Cream Butter and Sugar:
In your mixer beat the softened butter and sugar together on medium until it is very light and fluffy about one minute This helps make the base tender
Mix in Egg and Vanilla:

Combine Dry Ingredients:
In a separate bowl whisk the flour salt and baking powder together Gradually add to the wet mixture mixing until just combined The batter will be thick
Add Peppermint Candy:
Gently fold in the crushed peppermint candy Do not overmix as it can make the bars tough
Spread and Bake:
Press the thick dough evenly into the prepared pan Smooth the top with a spatula Bake at three hundred fifty degrees Fahrenheit for about twenty minutes or until the top is just golden brown and the center looks set Do not overbake or they will be dry
Cool and Remove:
Let the baked bars cool completely in the pan Use the edges of the parchment to gently lift the bars out in one piece
Make the Frosting:
Beat powdered sugar butter vanilla salt and milk together until smooth and fluffy If using cream cheese or white chocolate blend them in now
Frost and Garnish:
Spread the frosting evenly over the cooled bars Sprinkle extra crushed peppermint candy or festive sprinkles on top Lightly press the toppings so they adhere

Storage Tips

Store these bars in an airtight container at room temperature for up to three days They keep best in a single layer to preserve the frosting texture For longer storage refrigerate and bring to room temperature before serving The bars also freeze well Just wrap tightly and thaw at room temperature

Ingredient Substitutions

Swap the vanilla extract in the base or frosting for a little more peppermint extract if you prefer a stronger minty punch Use gluten free baking flour if someone has dietary needs Instead of peppermint bits try crushed spearmint candy canes or even mini chocolate chips for a fun variation

Serving Suggestions

These bars are wonderful for holiday dessert tables Consider serving them with mugs of hot cocoa or peppermint tea For a more decadent treat cut into small squares and layer with chocolate sauce and whipped cream
