Blueberry Lemon Blondies
I’m ready for Summer! This is a perfect dessert for any occasion. The zest of the lemon pairs well with the blueberry. Take it up a notch with the lemon glaze.
Every other week, we have Sunday dinner with the whole family. I love it!! It’s so fun to see all the kids play together and have a bond that is priceless. The other highlight of the day, is the FOOD! We always have a different theme for each dinner. My kids are such great cooks, it’s fun to see what they bring to the table.
Since there are so many of us, there are times that we try to keep it simple, and this week that was the case. We had a make your own sub bar, with salads on the side. Nobody signed up for desserts, so stepped up to the plate, You can’t go wrong with, blueberries, lemon, and cookies. I haven’t met a cookie that I didn’t love!
TIPS AND TRICKS
BUTTER: Make sure your butter is room temperature. If you need to soften it a little in the microwave, make sure it’s not too hot. The blondies won’t bake evenly if that’s the case.
DON’T OVER MIX: If you over mix, the blondies won’t be as fluffy. When you add the blueberries, make sure to blend gently, so you don’t crush the berries.
BLUEBERRIES: I didn’t add enough blueberries when I made this recipe. I added 1 cup, but I think it would be so much better with 2 cups.
PERFECT BAKE: Make sure to bake them until you can insert a toothpick and it comes out clean. You can also, gently press on the top, and if it bounces back, it’s done.
STORING: You can store them in an airtight container for up to 4 days. You can also freeze them in an airtight container up to 3 months.
Blueberry Lemon Blondies

Ingredients
- For the Blondies:
- ¾ cup butter
- 2 ounces white chocolate chips
- 1 cup packed light brown sugar
- 2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon salt
- 1 large egg
- 1 large egg yolk
- 1 teaspoon vanilla
- 1/2 teaspoon baking powder
- 1/4 teaspoon baking soda
- 2 cups flour
- 2 cups fresh blueberries
- For the Lemon Glaze:
- ⅔ cup powdered sugar
- 4 teaspoons fresh lemon juice
Instructions
- Preheat the oven to 350 degrees F (175 degrees C). Grease and line a 9-inch square baking pan with parchment paper, allowing a 1-inch overhang.
- Melt butter in a small saucepan over medium heat. Add white chocolate and stir until chocolate is melted and incorporated with the butter. Scrape mixture into a large mixing bowl and whisk in the brown sugar until smooth. Whisk in the lemon juice, zest, and salt until all is combined. Whisk in egg, egg yolk, and vanilla extract.
- Stir in baking powder, baking soda, and flour. Using a rubber spatula, fold in blueberries. Scrape batter into the prepared pan and smooth into an even layer; it will be a bit thick.
- Bake in the preheated oven until golden brown, 30 to 35 minutes. Transfer to a wire rack and allow blondies to cool for at least 15 minutes in the pan. When ready to serve, lift the blondies out of the pan using the parchment paper overhang and place on a cutting board.
- To make the glaze: Whisk powdered sugar and lemon juice together in a small bowl until smooth. Drizzle over the blondies. Slice and serve.
