Kitchen Tools You’ll Need
- 8×8-inch baking pan
- Parchment paper or foil
- Mixing bowls
- Whisk
- Spatula
Ingredients
- 1¾ cups all-purpose flour (210g)
- 1 teaspoon baking powder
- ¼ teaspoon baking soda
- ¾ teaspoon salt
- 1 cup packed light brown sugar (220g)
- ½ cup unsalted butter melted (113g)
- 1 large egg room temperature
- 2 teaspoons vanilla extract
- 1 cup mix-in’s such as white, semi-sweet chocolate or butterscotch chips; chopped nuts such as walnuts, pecans, or almonds (180g)
How to Make Blondie Recipe
Step 1. Preheat your oven to 350°F. It’s important to ensure your oven reaches the right temperature before baking, as this impacts how evenly the blondies will cook. While it preheats, prepare your baking pan by lining an 8×8-inch dish with parchment paper or foil. Leave a 2-inch overhang on at least two sides; this will help you lift the blondies out of the pan later for easy cutting.
Step 2. In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until they are evenly combined. This step ensures that your leavening agents are distributed throughout the flour, which helps the blondies rise properly during baking.
Step 3. In a large mixing bowl, whisk together the packed light brown sugar and melted unsalted butter until the mixture is well combined and free of lumps. The brown sugar not only adds sweetness but also contributes to the blondies’ rich flavor and moist texture.
Step 4. Add the room-temperature egg and 2 teaspoons of vanilla extract to the brown sugar mixture. Whisk vigorously for a few minutes until the mixture becomes thick and creamy. This step incorporates air, which helps create a softer texture in the finished blondies.
Step 5. Gently fold the dry mixture into the wet ingredients using a spatula. Mix until just combined, taking care not to overwork the batter. Overmixing can lead to denser blondies, so stop as soon as you no longer see streaks of flour.
Step 6. Carefully add ¾ cup of your chosen mix-ins to the batter and stir until evenly distributed. These mix-ins can add delightful pockets of flavor, whether you choose chocolate chips or nuts, enhancing the overall eating experience.
Step 7. Transfer the batter to the prepared baking pan and spread it into an even layer with your spatula. The surface should be smooth so that the blondies bake evenly. Once spread, press the remaining ¼ cup of mix-ins into the top for an attractive finish.
Step 8. Place the pan in the preheated oven and bake for 32 to 36 minutes. Keep an eye on the edges as they should begin to set and turn a golden brown. A toothpick inserted into the center will help you ensure they are baked: if it comes out clean, your blondies are done.
Step 9. Allow the blondies to cool completely in the pan before cutting them into squares. This cooling period helps them firm up, making cutting easier and resulting in cleaner edges.

Pro Tips for Best Results
- Room Temperature Ingredients: Ensure your egg and butter are at room temperature for smoother mixing and better texture.
- Don’t Overmix: Mixing just until combined is key to achieving the light and chewy texture characteristic of good blondies.
- Check Doneness Carefully: Every oven is different; use a toothpick to test doneness, ensuring it comes out clean without overbaking.
- Use Quality Mix-ins: Choosing high-quality chocolate or nuts can elevate the flavor of your blondies significantly.
- Cool Completely: Allowing the blondies to cool fully in the pan helps retain their moistness and makes them easier to cut.
Common Mistakes to Avoid
- Using Cold Ingredients: Baking with cold butter or eggs can lead to a lumpy batter. Always let them come to room temperature to ensure a smooth mixture.
- Overmixing the Batter: Mixing too much can create tough blondies. Stir just until everything is combined for the best texture.
- Not Measuring Properly: Accurate measurements are crucial in baking. Too much flour can make them dry, while too little sugar can lead to blandness.
- Ignoring the Oven Temperature: An incorrectly set oven can affect baking time and texture. Always preheat and check your oven’s accuracy with an additional thermometer if needed.
- Cutting Before Cooling: If you cut them too soon, they may fall apart. Let the blondies cool completely in the pan for the best results.
- Using the Wrong Pan Size: Using a different size pan will affect baking time and the final texture of the blondies. Stick with the recommended 8×8-inch pan for even baking.
Variations & Substitutions
You might want to try adding different mix-ins for variety. Instead of chocolate chips, consider using butterscotch chips or dried fruits for a different flavor profile. Chopped nuts can provide a pleasing crunch. If you’re looking for a slightly different taste, consider adding a pinch of cinnamon or nutmeg to the dry ingredients for added warmth.
Storage & Reheating
These blondies can be stored at room temperature in an airtight container for up to a week. For longer storage, refrigerate them in an airtight container, where they can last for up to ten days. If you’d like to keep them even longer, you can freeze the blondies wrapped well in plastic wrap and then placed in a freezer bag. To reheat, let them come to room temperature or warm them briefly in the microwave, which will soften their texture without drying them out.
