Blueberry Lemon Blondies Ingredients

Lemon oil adds amazing lemon flavor to your blondies with just a couple of drops. Use lemon oil instead of lemon extract if you have it available.

You can make a lemon-flavored glaze instead of the blueberry glaze.  Just whisk together powdered sugar, a couple of drops of lemon oil or lemon extract, and cream until the glaze is spreadable. If you’d like you can add purple, blue, or even yellow food coloring to the glaze.

Whipping the eggs ahead of time gives a nice lift to the blondie batter while keeping them nice and fudgey. You can also increase the flour by a ¼-½ cup if you want a fluffier center. Just make sure not to overmix your batter, or you may end up with crumbly bars.

How to Make Blueberry Lemon Blondies

FIRST STEP: Preheat the oven to 350°F. Line a 9x13 glass baking dish with parchment paper and set it aside.

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

THIRD STEP: Add in 1½ cups granulated sugar and continue whisking at high speed until foamy and thickened.

FOURTH STEP: Add melted butter, lemon juice, lemon zest, vanilla extract, and lemon oil/extract. Beat on medium speed until combined.

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

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

SEVENTH STEP: Gently fold in blueberries, just until combined.

EIGHTH STEP: Spread the mixture into the prepared baking dish.

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

TENTH STEP: To make the glaze, heat ½ cup of blueberries and ½ cup of sugar in a small saucepan over medium heat. You can add a splash of water (1 tablespoon) to help the mixture. Heat, stirring constantly until sugar is dissolved and blueberries have formed a vibrant syrup.

ELEVENTH STEP: Stir the syrup through a sieve into a bowl with ½ cup of powdered sugar. Whisk until combined, adding a splash of heavy cream or milk to help smooth the glaze into a spreadable consistency.

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

THIRTEENTH STEP: Cut into squares and serve. 

Can I use frozen blueberries? 

You can use frozen blueberries instead of fresh blueberries in this blueberry lemon blondies dessert bars recipe. 

What can I add to this blondie's recipe? 

You can add chopped walnuts or other chopped nuts to these lemon bars for a bit of extra crunch. For a burst of sweetness, mix white chocolate chips or even milk chocolate chips into the batter. Instead of the glaze, you can top your blueberry lemon blondies with lemon curd or lemon buttercream. 

What is the difference between a blondie and a brownie?

The main difference between blondies and brownies is chocolate. Brownies use cocoa powder or melted chocolate mixed throughout the batter.
