- 1/2 teaspoon baking soda

Prep & Cook Tools

- Large mixing bowl: For combining all your ingredients.
- Whisk: To blend the wet ingredients smoothly.

One Bowl Blondies in Steps
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) to ensure it’s ready for baking.
Step 2: Melt the Butter
In a large mixing bowl, melt the butter in the microwave or on the stovetop. Allow it to cool slightly before proceeding to the next step.
Step 3: Combine the Sugars
Add the packed dark brown sugar to the melted butter and whisk until well combined. This is where the magic begins; the sugar will dissolve, creating a rich base.
Step 4: Add the Eggs and Vanilla
Next, lightly beat the eggs in a separate bowl, then add them along with the vanilla extract to the sugar mixture. Whisk until fully incorporated.
Step 5: Mix the Dry Ingredients
In the same bowl, add the all-purpose flour, baking powder, baking soda, and salt. Use a rubber spatula to gently fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix; it’s okay if there are a few lumps.
Step 6: Fold in the Chocolate Chips and Toffee
Gently fold in the chocolate chips and toffee pieces. This step adds a delightful crunch and bursts of flavor in every bite!
Step 7: Prepare the Baking Pan
Line your baking pan with parchment paper for easy removal or simply grease it with butter or cooking spray.
Step 8: Pour and Spread the Batter
Pour the blondie batter into the prepared baking pan, spreading it evenly with your spatula.
Step 9: Add Flaked Sea Salt
Sprinkle a little flaked sea salt on top of the batter for that perfect sweet-salty balance.
Step 10: Bake!
Bake in the preheated oven for 20-25 minutes or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs.
Step 11: Cool and Slice
Allow the blondies to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely. Once cooled, slice into squares and enjoy!
Healthier Substitutions
- Coconut oil: Substitute melted butter with melted coconut oil for a dairy-free option.
- Whole wheat flour: Swap all-purpose flour with whole wheat flour for added nutrition.
- Reduce sugar: You can decrease the amount of brown sugar by 1/2 cup for a less sweet version.
- Dark chocolate chips: Use dark chocolate chips to lower sugar content and increase antioxidants.

Can I use salted butter instead of unsalted?
Yes, you can use salted butter, but be sure to reduce the added salt in the recipe to 1/4 teaspoon to balance the flavors.

If you don’t have toffee pieces, chopped caramel candies or even crushed cookies can add a delightful crunch and sweetness.

Your blondies are done when the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs, not wet batter.
