Ingredients

Scale

Dry Ingredients

  • 1 teaspoon salt
  • pinch of ground nutmeg
  • 11/2 cups all-purpose flour
  • 1 teaspoon baking powder

Wet Ingredients

  • 1/2 cup unsalted butter, room temperature
  • 1 cup white granulated sugar
  • 1/2 cup light brown sugar, packed
  • 11/2 teaspoons vanilla extract
  • 2 eggs, room temperature

Add-ins

  • 1 cup toffee pieces
  • 1 cup milk chocolate chips

Instructions

  1. Prepare the pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with foil and lightly spray the bottom and sides with baking spray to prevent sticking.
  2. Cream butter and sugars: In a stand mixer fitted with the paddle attachment, beat the room temperature butter on medium-high speed until it turns pale. Add the white granulated sugar and packed light brown sugar, then continue mixing on medium-high until the mixture becomes light and fluffy. Scrape down the bowl sides as necessary to ensure even mixing. Add the vanilla extract and mix briefly.
  3. Add eggs: Incorporate the eggs one at a time into the sugar-butter mixture, mixing on medium speed after each addition until fully combined.
  4. Combine dry ingredients: Lower the mixer speed to low and slowly add the salt, ground nutmeg, all-purpose flour, and baking powder to the wet mixture. Mix just until the ingredients are barely combined.
  5. Fold in toffee and chocolate chips: Remove the mixing bowl from the stand mixer. Use a rubber spatula to gently fold in the toffee pieces and milk chocolate chips, ensuring even distribution without overmixing.
  6. Spread batter: Transfer the dough into the prepared baking pan. Wet your fingertips with water and use them to spread the sticky dough evenly across the pan for a uniform thickness.
  7. Bake: Place the pan in the preheated oven and bake the blondies for 20 to 25 minutes, or until a toothpick inserted in the center comes out with no raw batter (a few moist crumbs are fine). Take care not to overbake to keep the bars moist and chewy.
  8. Cool and cut: Allow the blondies to cool completely in the pan for 2 to 3 hours so they set properly. Once fully cooled, lift them out using the foil and cut into squares of your preferred size.

Notes

  • Use room temperature butter and eggs for better mixing and a smoother batter.
  • Do not overbake to keep the blondies moist and chewy; check at 20 minutes.
  • You can substitute dark chocolate chips for a richer flavor if desired.
  • To make clean cuts, use a sharp knife and wipe it off between cuts.
  • Store blondies in an airtight container at room temperature for up to 4 days or freeze for longer storage.
