For the Blondies

1 Cup unsalted butter (at room temperature (2 sticks))
3/4 Cup sugar
2 large eggs
2/3 Cup fresh squeezed lemon juice
2 1/4 Cups all purpose flour
1 teaspoon baking powder
1/2 teaspoon salt
1 Cup frozen blackberries (chopped)

For the Blackberry Glaze

1 Cup frozen blackberries
2 Tablespoons sugar
2 Tablespoons lemon juice
1 Cup powdered sugar


For the Blondies

Step 1
Preheat oven to 350°F.

Step 2
Line a 9-inch square baking pan with parchment paper or spray with cooking spray.

Step 3
Beat together the butter and sugar until fluffy. Add the eggs.

Step 4
Once the eggs are incorporated, add lemon juice and combine.

Step 5
Whisk together flour, baking powder and salt, then add to the wet ingredients, mixing until just combined.

Step 6
Fold in the chopped frozen blackberries.

Step 7
Using a rubber spatula, spread the batter into the prepared pan.

Step 8
Bake 30-35 minutes, until cooked through. Edges will be slightly browned and a toothpick inserted in the center will come out clean. Let cool completely (about 1 hour).

For the Blackberry Glaze

Step 1
In a small saucepan combine blackberries, sugar and lemon juice. Bring to a boil, reduce heat and simmer 2-3 minutes, until sugar dissolves and the blackberries start to break down. Process with a food processor or blender, then pass through a fine mesh sieve to get rid of any seeds.

Step 2
Add powdered sugar to a small bowl and start by adding the berry puree, tablespoon by tablespoon, until the glaze is your desired consistency. Spread glaze over cooled blondies and serve.
