How to Make Blueberry Lemon Blondies

Ready to get baking? Let's dive in! Start by heating your oven to 350F and lining your baking dish with parchment paper. Make sure to leave some extra parchment paper hanging over the sides – this will make taking the blondies out of the baking dish a breeze. Sift flour, baking powder, and salt in a large bowl. Sifting is a must as it will reduce the number of lumps in your batter.

In a second bowl, cream butter, sugar, and lemon zest until it's fluffy. Whisk in the egg, followed by the lemon juice. Gradually beat in the flour mixture until just combined – don't overmix the batter. Gently fold the blueberries into the batter.

Pour the batter into your baking dish and bake the blondies for about 25 to 30 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and let cool completely. Once the blondies have cooled, blitz the lemon juice and frozen blueberries in a blender.

Strain out the solids, then whisk with powdered sugar and 1 tablespoon of lemon juice. Pour the glaze over the blondies and leave it to set for 10 to 15 minutes. Slice the blondies and serve.

Tips for the Best Blueberry Lemon Blondies

Make sure to use room-temperature ingredients when making your blueberry lemon blondies.

Use fresh or frozen blueberries to make your blondies.

Don't overmix your batter.

Use enough parchment paper so you can have some overhang – this will make it easier to take the blondies out of your baking dish.

Your blondies are done cooking when they turn lightly golden around the edges and a toothpick inserted into the center comes out mostly clean and crumb-free.

You can add in other tasty ingredients like raspberries, strawberries, dried cranberries, chocolate chips, chopped nuts, candied citrus peel, or use brown butter.
