Ingredients
- 1/2 cup unsalted butter, room temperature
- 1 cup white granulated sugar
- 1/2 cup light brown sugar, packed
- 1 1/2 teaspoons vanilla extract
- 2 eggs, room temperature
- 1 teaspoon salt
- pinch of ground nutmeg
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1 cup toffee pieces
- 1 cup milk chocolate chips
Instructions
- Step 1: Preheat the oven to 350 degrees Fahrenheit. Line a 9×13-inch baking pan with foil and spray the bottom and sides with baking spray. Set aside.
- Step 2: In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium-high speed until pale in color. Add both the white sugar and brown sugar and continue mixing on medium-high speed until the mixture is light and fluffy. Scrape down the sides of the bowl as needed. Add the vanilla extract.
- Step 3: Beat in the eggs one at a time, mixing on medium speed until incorporated.
- Step 4: Reduce the mixer speed to low. Gradually add the salt, nutmeg, flour, and baking powder. Mix just until the ingredients are barely combined. Remove the bowl from the mixer and use a rubber spatula to fold in the toffee pieces and milk chocolate chips evenly.
- Step 5: Transfer the dough into the prepared pan. Wet your fingertips with water and gently spread the sticky dough into an even layer across the pan.
- Step 6: Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean without raw batter. Avoid overbaking to keep the blondies moist.
- Step 7: Allow the blondies to cool completely in the pan for 2-3 hours. Once cooled, lift the blondies out using the foil and cut into squares as desired.
Tips & Variations
- For extra richness, substitute half of the white sugar with light brown sugar to enhance the caramel notes.
- Try adding chopped nuts like pecans or walnuts for additional texture and flavor.
- If you prefer darker chocolate, swap the milk chocolate chips for semi-sweet or dark chocolate chips.
- Make sure the butter and eggs are at room temperature to ensure smooth mixing and better texture.
Storage
Store the blondie bars in an airtight container at room temperature for up to 3 days. For longer storage, wrap tightly and freeze for up to 2 months. To reheat, warm individual bars in the microwave for about 10-15 seconds or enjoy them at room temperature for the best texture.

Ingredients
Dry Ingredients
- 1 teaspoon salt
- pinch of ground nutmeg
- 1–1/2 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
- 1–1/2 teaspoons vanilla extract
- 2 eggs, room temperature
Add-ins
- 1 cup toffee pieces
- 1 cup milk chocolate chips
Instructions
- 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.
- 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.
- Add eggs: Incorporate the eggs one at a time into the sugar-butter mixture, mixing on medium speed after each addition until fully combined.
- 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.
- 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.
- 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.
- 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.
- 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.
