Step 1

Preheat your oven to 375 degrees Fahrenheit. Spray a 10-inch cast-iron skillet with baking spray and set aside.

Step 2

In a large mixing bowl, whisk together melted butter, brown sugar, vanilla, and eggs until combined.

Step 3

In a separate medium mixing bowl, whisk together flour, baking powder, and salt. Add flour mixture to the bowl with the butter mixture and combine mix with a rubber spatula until just combined and no more dry flour is visible.

Step 4

Fold in crushed peppermint and dark chocolate chunks until mixed into the batter. Pour blondie batter into the prepared cast-iron skillet and smooth out into an even layer.

Step 5

Bake blondie in the preheated oven for 25-30 minutes until the edges are set and the center is still gooey. The center will look slightly underbaked. Cool in the skillet for 10-15 minutes.

Step 6

While the blondie is cooling, add powdered sugar, peppermint extract, and two tablespoons of heavy cream to a medium mixing bowl. Whisk together until combined. Add more heavy cream as needed until glaze is smooth and able to be drizzled easily with a spoon.

Step 7

Drizzle glaze over warm blondie and top with more crushed candy canes if desired. Enjoy!
