Step‑by‑Step Instructions for Lemon-Glazed Blueberry Blondies
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, allowing some overhang for easy removal later. This creates the perfect base for your Blueberry Blondies, ensuring they bake evenly while also making cleanup a breeze.
Step 2: Melt the Butter
In a microwave-safe bowl, melt ½ cup of unsalted butter until it's completely liquid, which should take about 30 seconds to a minute. Allow the melted butter to cool slightly at room temperature while you gather the other ingredients, ensuring it won't scramble the egg when mixed.
Step 3: Mix the Wet Ingredients
Once the butter has cooled, whisk it together with 1 cup of granulated sugar, 1 large egg, and 1 teaspoon of vanilla extract in the same bowl. Mix until the batter is smooth and glossy, approximately 1–2 minutes. This combination will create a rich base for your luscious Blueberry Blondies.
Step 4: Combine Dry Ingredients
Gently fold in 1 cup of all-purpose flour, ½ teaspoon of salt, and the zest of one lemon into the wet mixture. Use a spatula to combine until just incorporated—be careful not to overmix, as this could alter the texture of your blondies, making them tough instead of chewy.
Step 5: Add the Blueberries
Now, it’s time to add the star ingredient! Gently fold in 1 cup of fresh blueberries, or if using frozen, coat them lightly in flour first. This step helps distribute the berries evenly throughout the batter and prevents them from sinking, keeping your Blueberry Blondies vibrant and colorful.
Step 6: Spread and Bake
Pour the blondie batter into the prepared pan, spreading it evenly with a spatula. Bake in your preheated oven for 25–30 minutes, or until the edges are golden and a toothpick inserted in the center comes out with a few moist crumbs attached. Keep an eye on them as they bake for that perfect balance of chewy and tender.
Step 7: Cool and Remove
Once baked to perfection, remove the blondies from the oven and let them cool in the pan for 10-15 minutes. This cooling period is essential for the texture, allowing them to set before lifting them out with the parchment overhang, making cutting into squares easier when fully cooled.
Step 8: Prepare the Lemon Glaze
While the blondies cool, whisk together 1 cup of powdered sugar and 2 tablespoons of fresh lemon juice in a small bowl until smooth. The glaze should be thick yet pourable, providing a sweet, zesty finish that will elevate your Blueberry Blondies to a whole new level.
Step 9: Drizzle and Set
Once the blondies have completely cooled, drizzle the lemon glaze generously over the top, allowing it to cascade down the sides. Let the glaze set for a few minutes before slicing the blondies into squares. This final touch brings everything together beautifully, ready for you to enjoy!
How to Store and Freeze Blueberry Blondies
Room Temperature: Store your Blueberry Blondies in an airtight container at room temperature for up to 3 days. This keeps them soft and chewy, perfect for snacking.
Fridge: If you prefer a firmer texture, keep the blondies in the fridge for up to a week. Just make sure they’re wrapped tightly to prevent drying out.
Freezer: For longer storage, freeze the blondies for up to 3 months. Wrap them individually in plastic wrap and place them in a freezer-safe bag or container.
Reheating: To enjoy them warm, reheat in the microwave for 10-15 seconds or in an oven at 350°F (175°C) for about 5 minutes. This will revive the soft, gooey center and the zesty lemon glaze!

What are some common issues when making blondies and how can I avoid them?
Very! One common issue is overmixing the batter, which can lead to tough blondies instead of the desired chewy texture. Be sure to fold the ingredients together gently until just combined.
