Equipment
Ingredients
Blondies
- 1 cup unsalted butter, melted
- 1 cup granulated sugar
- ⅓ cup light brown sugar, lightly packed
- 1 tbsp vanilla extract
- 2 large eggs
- 2 ½ cups all-purpose flour, fluffed, spooned and leveled
- 1 ¼ tsp baking powder
- ½ tsp coarse Kosher salt (if using table salt, use half the amount)
Frosting
- ¾ cup unsalted butter, softened to room temperature
- 1 ½ cups powdered sugar
- ½ tsp peppermint (not mint) extract
- ¾ tsp vanilla extract
- peppermint candy or candy canes
Instructions
Blondies
- Preheat the oven to 350 F, and position a rack in the center of the oven. Line a 9-inch baking pan with parchment paper, or spray the pan with non stick baking spray.
- In a bowl, whisk together the melted butter, granulated sugar and brown sugar, then whisk in the eggs and vanilla until smooth.
- Separately, sift together the flour, baking powder and salt. Add the dry ingredients to the wet, and stir everything together with a spatula into a soft dough.
- Spread the dough evenly into the prepared pan, and bake for 28-30 minutes. The edges should be set and the top golden brown and slightly puffed, but the cookie bars will still be underdone under the crust. Do not over bake, or they will end up dry.
- Set the pan on a cooling rack, and cool completely, at least 4 hours, before frosting.
Frosting
- With an electric mixer, beat the butter for 1 minute until smooth. Add the powdered sugar, peppermint extract and vanilla extract, and beat for several minutes, until light and fluffy.
- Spread the frosting over the cooled blondies and cut into squares. Before serving, decorate with crushed peppermints or candy canes.Baker's Note: Peppermint candy can melt and get sticky on top when the blondies are stored in a container, so I suggest waiting until ready to serve them before adding the candy.
Notes
Store leftover blondies in an airtight container at room temperature for up to 3 days.
