Ingredients
- 1 stick + 5 tablespoons (13 tablespoons total) unsalted butter, melted
- 1 1/2 cups dark brown sugar
- 1 teaspoon vanilla or almond extract
- 2 large eggs, at room temperature
- 2 cups + 2 tablespoons all purpose flour
- 1/2 teaspoon salt
- 1 teaspoon espresso powder
- 1 cup toffee pieces (homemade or Heath Bar chips)
- 1 cup milk chocolate or dark chocolate chips
Instructions
- Step 1: Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper and lightly grease it. Set aside.
- Step 2: In a large bowl, cream together the melted butter, dark brown sugar, and vanilla or almond extract until well combined.
- Step 3: Add the eggs and beat thoroughly until the mixture is smooth and creamy.
- Step 4: Gently stir in the all-purpose flour, salt, and espresso powder, mixing just until you see small traces of flour remaining.
- Step 5: Fold in most of the toffee pieces and chocolate chips, reserving about 1/4 cup of each to sprinkle on top of the batter.
- Step 6: Pour the batter evenly into the prepared pan. Sprinkle the reserved toffee and chocolate chips over the top.
- Step 7: Bake for about 28 minutes, or until the top is golden and the center is mostly set but still slightly wobbly for a gooey texture.
- Step 8: Allow the blondies to cool in the pan before cutting into bars and serving.
Tips & Variations

- For a stronger coffee flavor, increase espresso powder to 1 1/2 teaspoons.

FAQs
Can I substitute the toffee pieces with something else?
Yes, crushed butterscotch chips or caramel bits can be used as a substitute for toffee pieces to maintain a similar flavor and texture.
How do I know when the blondies are done baking?
The blondies are done when the top is golden and the center is mostly set but may have a slight wobble. This ensures a moist and gooey texture without being underbaked.

Ingredients
Main Ingredients
- 1 stick + 5 tablespoons (13 tablespoons total) unsalted butter, melted
- 1 1/2 cups dark brown sugar
- 1 teaspoon vanilla or almond extract
- 2 large eggs, at room temperature
- 2 cups + 2 tablespoons all-purpose flour
- 1/2 teaspoon salt
- 1 teaspoon espresso powder
- 1 cup toffee pieces (homemade or Heath Bar chips)
- 1 cup milk chocolate or dark chocolate chips
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper and lightly grease it to prevent sticking.
- Cream Butter and Sugar: In a large bowl, combine the melted butter, dark brown sugar, and vanilla or almond extract. Mix until the ingredients are well blended and smooth.
- Add Eggs: Add the room temperature eggs to the butter and sugar mixture. Beat well until the batter is smooth and fully incorporated.
- Incorporate Dry Ingredients: Gently stir in the all-purpose flour, salt, and espresso powder. Mix carefully just until you see small traces of flour remaining; avoid overmixing to keep the blondies tender.
- Fold in Toffee and Chocolate Chips: Fold in almost all of the toffee pieces and chocolate chips, reserving about 1/4 cup of each to sprinkle on top later. This ensures even distribution throughout the batter.
- Pour and Sprinkle: Pour the batter evenly into the prepared pan. Sprinkle the reserved toffee pieces and chocolate chips on top for a delicious crunchy topping.
- Bake: Bake in the preheated oven for approximately 28 minutes, or until the top is golden brown and the center is mostly set but may have a slight wobble, if you prefer a gooey texture.
- Cool and Serve: Allow the blondies to cool in the pan before slicing into bars and serving to let them set perfectly.
Notes
- Use room temperature eggs for better batter consistency and texture.
- You can substitute Heath Bar chips for the toffee if desired.
- The slight wobble in the center indicates a gooier blondie; bake longer if you prefer a firmer bar.
- Line the pan with parchment paper for easier removal and cleanup.
- Espresso powder enhances the chocolate flavor but can be omitted if preferred.
