How to Make Lemon Blackberry Blondies – Step by Step
Prepare the Berries and Pan
Step 1: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving some overhang for easy removal later.
Step 2: If using frozen blackberries, measure them and set aside to thaw slightly while preparing the batter. If using fresh berries, rinse and pat them dry.
Create the Blondie Batter
Step 3: In a large bowl, cream together the softened butter and white sugar until light and fluffy, about 2-3 minutes.
Step 4: Add salt, lemon zest, lemon juice, and vanilla extract to the butter mixture. Beat until well combined and fragrant.
Step 5: In a separate bowl, whisk together flour, cornstarch, and baking powder.
Step 6: Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to overmix, which can make your lemon blackberry blondies tough rather than tender.
Add Berries and Bake
Step 7: Gently fold in the blackberries, being careful not to crush them. The batter will be thick.
Step 8: Spread the batter evenly in the prepared pan. If making lemon blackberry blondies with white chocolate, sprinkle 1/3 cup white chocolate chips over the batter now.
Step 9: Bake for 25-30 minutes, until the edges are golden brown and a toothpick inserted in the center comes out with moist crumbs (not wet batter).
Step 10: Allow to cool in the pan for 10 minutes, then use the parchment overhang to lift the blondies out and place on a wire rack to cool completely.
Make the Lemon Glaze
Step 11: While the blondies cool, prepare the glaze by whisking together confectioners sugar, salt, lemon juice, and heavy cream until smooth. Adjust consistency as needed with additional cream or sugar.
Step 12: Once the blondies are completely cool, drizzle with the lemon glaze and allow it to set before cutting into squares.

Pro Tips for Making the Best Lemon Blackberry Blondies

- Let the blondies cool completely before glazing and cutting for the neatest squares
