Blueberry Lemon Blondies Ingredients
- Eggs - large eggs
- Sugar - granulated sugar
- Butter - salted butter
- Lemon juice - fresh lemon juice
- Lemon zest - Zest of 1 lemon
- Vanilla extract
- Lemon extract - or 3-4 drops of lemon oil
- Flour - all-purpose flour
- Baking powder
- Blueberries - fresh blueberries
- Sugar - powdered sugar
- Heavy cream - or milk
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.

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

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.

What can I add to this blondie's recipe?
