Blueberry Lemon Blondies Ingredients

Substitutions And Additions

BLUEBERRIES: You can use frozen blueberries instead of fresh blueberries in this recipe. 

NUTS: Add chopped walnuts or other chopped nuts to these lemon bars for a bit of extra crunch. 

TOPPING: For a different spin on the topping for this blueberry dessert, try lemon curd or lemon buttercream for added fresh flavor instead of your glaze. 

CHOCOLATE CHIPS: For a burst of sweetness, mix white chocolate chips or even milk chocolate chips into the batter. 

LEMON ZEST: If you don’t have fresh lemons for zest, you can substitute with lemon extract or lemon juice.

Start with one-half to one teaspoon of lemon extract or one to two tablespoons of lemon juice, depending on your preference for lemon flavor.

Adjust to taste, as extracts and juices can vary in intensity.

VANILLA EXTRACT: While vanilla extract is commonly used, you can switch things up by using almond extract or orange extract for a different flavor twist.

Start with a half teaspoon of the alternate extract and adjust to taste.

How To Make This Blueberry Lemon Blondies Recipe

Our simple directions below will walk you through making these delicious squares.

STEP ONE: Preheat the oven to 350°F. Line a 9×13-inch glass baking dish with parchment paper and set it aside. 

STEP TWO: In a stand mixer or with a hand mixer, whisk the eggs on high until very frothy. 

STEP THREE: Add 1½ cups of granulated sugar and continue whisking with the electric mixer at high speed until foamy and thickened. 

STEP FOUR: Add the melted butter, lemon juice, lemon zest, vanilla extract, and lemon oil/extract to the egg mixture. Beat on medium speed until combined. 

STEP FIVE: In a separate bowl, combine flour and baking powder. 

STEP SIX: Add the flour mixture to the wet ingredients and mix just until combined. 

STEP SEVEN: Gently fold in the blueberries just until combined. 

STEP EIGHT: Spread the mixture into the prepared pan. 

STEP NINE: Bake blondies for 30 minutes or until a toothpick inserted in the center comes out clean. 

STEP TEN: To make the glaze, heat a half cup of blueberries and a half cup of sugar in a small saucepan over medium heat.

You can add a splash of water (one tablespoon) to help the mixture.

Heat, stirring constantly, until the sugar is dissolved and the blueberries have formed a vibrant syrup. 

STEP ELEVEN: Stir the syrup through a sieve into a bowl with a half cup of powdered sugar.

Whisk until combined, adding a splash of heavy cream or milk to help smooth the glaze into a spreadable consistency. 

STEP TWELVE: Spread glaze over warm baked blondies and allow them to cool the rest of the way. 

STEP THIRTEEN: Cut into squares and serve.

How To Serve Lemon Blueberry Brownies

Storing Lemon Blueberry Blondies

Now that you’ve enjoyed these blueberry lemon blondies, it’s essential to know how to store them to keep their freshness intact.

MAKE AHEAD: If you’re planning ahead for a special occasion or simply want to prep in advance, you can make the blondies a day or two before serving.

Follow the recipe as usual, allow them to cool completely in the baking pan, and then cover the pan with plastic wrap or aluminum foil.

You can store them at room temperature for up to 24 hours before serving.

ON THE COUNTER: Lemon blueberry blondies can be left out at room temperature.

To keep them fresh, wrap them tightly in plastic wrap or foil or store them in an airtight container. Stored this way, they should stay fresh for about three days. 

Uncut blondies will stay fresher for longer than individually cut blondies, so if you are making them ahead, wait until the day you are serving them to cut them. 

IN THE FRIDGE: If you want to keep these lemon blueberry blondie bars for longer, this easy blondie recipe can be stored in the fridge for a week.

Wrap the blondie bars tightly with plastic wrap to keep the air from getting in and drying them out. 

IN THE FREEZER: Store these delicious lemon blueberry blondies in the freezer for up to three months. Thaw on the counter when you are ready to serve them.
