Ingredients
Here’s a list of the ingredients you’ll need to make these delicious blueberry lemon blondies. Don’t worry, these are common pantry staples, so you likely have most of them at home already!
For the Blondies:
- 1 cup all-purpose flour (spooned & leveled)
- ¼ teaspoon baking powder
- ¼ teaspoon salt
- ½ cup unsalted butter (room temperature)
- ¾ cup granulated sugar
- Grated zest from 1 lemon
- 1 large egg (room temperature)
- ¼ cup freshly squeezed lemon juice
- 1 cup fresh blueberries
For the Glaze:
- 1 cup powdered sugar (sifted)
- 2 Tablespoons lemon juice
- 1 heaping tablespoon frozen blueberries (for a burst of color and flavor)
Variations for Blueberry Lemon Blondies
While this recipe is absolutely perfect as it is, there are a few fun variations you can try to personalize it:
- Add White Chocolate Chips: For an extra creamy and rich element, fold in ½ cup of white chocolate chips along with the blueberries.
- Use Frozen Blueberries: If fresh blueberries are not available, frozen blueberries work just as well. Just make sure to fold them in gently to avoid color bleeding.
- Try Lemon Extract: If you want to intensify the lemon flavor, consider adding a few drops of lemon extract in addition to the zest and juice.
- Make It Gluten-Free: Substitute the all-purpose flour with a gluten-free blend to make this dessert gluten-free.
- Top with Nuts: Add chopped nuts such as pecans or almonds to the batter for added crunch.

Step-by-Step Instructions
1. Preheat and Prepare the Pan
First things first, preheat your oven to 350°F (177°C). While the oven is heating up, grease a 9×9-inch baking pan with non-stick spray, or line it with parchment paper for easy removal.
2. Combine Dry Ingredients
In a medium-sized mixing bowl, whisk together the all-purpose flour, baking powder, and salt. Set this bowl aside while you prepare the wet ingredients.
3. Cream the Butter and Sugar
In a separate large bowl, cream together the unsalted butter and granulated sugar using a hand mixer or stand mixer on medium speed. Beat until the mixture is light and fluffy, about 3-4 minutes. This step is crucial to getting those perfectly soft blondies!
4. Add the Lemon Zest and Egg
Next, add the lemon zest and the large egg to the creamed butter and sugar. Beat until everything is well combined. The zest of one lemon will give the blondies a lovely fresh citrus aroma and flavor.
5. Add Lemon Juice
Pour in the freshly squeezed lemon juice. This will add that delightful tartness to balance out the sweetness of the sugar. Mix well until the batter is smooth.
6. Fold in Dry Ingredients
Gradually add the dry ingredients into the wet mixture. Using a spatula, gently fold the flour mixture into the wet ingredients until just combined. Be careful not to overmix; you want the batter to stay soft and fluffy.
7. Gently Fold in Blueberries
Carefully fold in the fresh blueberries. The key here is to handle the blueberries gently so that they don’t break or bleed too much into the batter.
8. Bake the Blondies
Pour the batter into the prepared 9×9-inch baking pan and spread it evenly. Bake in the preheated oven for 25-30 minutes. Keep an eye on the blondies and check for doneness by inserting a toothpick into the center. If it comes out clean (a few moist crumbs are okay), then your blondies are ready to come out of the oven.
9. Cool the Blondies
Once your blondies are baked, remove them from the oven and allow them to cool in the pan for 10-15 minutes. Afterward, transfer them to a wire rack to cool completely.
Preparing the Glaze
While the blondies are cooling, it’s time to make the lemon glaze. In a small bowl, combine the powdered sugar and lemon juice. Stir until the glaze is smooth and pourable. For added flavor and color, mash the frozen blueberries in a separate bowl and then fold them into the glaze.
Drizzle the Glaze
Once your blondies are fully cooled, drizzle the glaze over the top. You can use a spoon or a piping bag for a more controlled drizzle. The glaze will add an extra touch of sweetness and tang, complementing the blueberry lemon flavor perfectly.

How to Serve Blueberry Lemon Blondies
Blueberry Lemon Blondies are delicious on their own, but you can elevate your serving experience by trying these options:
- Serve with Whipped Cream: Top each blondie with a dollop of freshly whipped cream or even a scoop of vanilla ice cream.
- Pair with Tea: These blondies make a perfect snack with a cup of tea, especially with a light herbal or citrus-flavored tea.
- Garnish with Fresh Blueberries: For an extra burst of color, garnish each blondie with fresh blueberries before serving.
- Serve with a Fruit Compote: Top with a warm blueberry or lemon compote for a more indulgent treat.
Storing Blueberry Lemon Blondies
If you’re lucky enough to have leftovers (though I doubt you will!), here’s how to store them:
- Room Temperature: Keep your blondies in an airtight container at room temperature for up to 3-4 days. They’ll remain fresh and soft.
- Refrigerator: If you live in a warmer climate, you might want to store them in the fridge. Just make sure they are sealed tightly to avoid drying out.
- Freezing: These blondies freeze beautifully. Wrap them in plastic wrap and then place them in an airtight container. You can store them in the freezer for up to 3 months. When you’re ready to eat them, simply thaw them at room temperature or microwave them for a few seconds to warm them up.
