Ingredients You’ll Need
- unsalted butter
- light brown sugar
- large eggs
- vanilla extract
- large lemon
- all-purpose flour
- cornstarch
- baking powder
- salt
- fresh blueberries
- sliced almonds (optional)
- pure cane sugar (optional)
Step-By-Step Instructions
The first step will be to melt your butter in a small saucepan over medium heat, then you’ll add the melted butter to a large bowl. Stir in your brown sugar and mix with a rubber spatula until the sugar is dissolved and the mixture is smooth.
The second step will be to add your two eggs until well combined, followed by your lemon juice, lemon zest and vanilla extract. You’ll mix again until well combined.
The third step is to add your flour to a bowl followed by your cornstarch, baking powder and salt and whisk until well combined.
The fourth step is to add the flour mixture (minus one tablespoon) to the butter mixture until just combined.
You will sprinkle the one tablespoon flour over the blueberries and toss to coat, then fold into the dough.
The fifth and final step is to add the batter to your prepared pan and smooth the top with a rubber or offset spatula. Before baking, I like to sprinkle the top of the blondies with some sliced almonds for some crunch and a little bit of pure cane sugar. This is totally optional.
You’ll bake until the top is golden brown, about 22-25 minutes. You don’t want to overbake. Cool on a wire rack and then cut into squares.
You can serve these plain or topped with a scoop of vanilla ice cream. They’re so good guys. The blueberry/lemon combo is always a winner!

A Few Cook’s Notes for Blueberry Lemon Blondies
You will want to use a metal pan to make these blondies because a metal pan conducts heat more efficiently which leads to more even baking.
Everyone’s oven is a bit different, so check your blondies at 20 minutes. You do not want to overbake. I removed mine from the oven at 22 minutes.
These will be easier to cut if you wait until they’re cooled to room temperature.
