Description
A refreshing and sophisticated twist on the classic blondie. These bars feature a dense, fudgy texture infused with fresh lemon and bursting blueberries. The showstopper is a naturally vibrant ‘royal purple’ glaze made from frozen blueberry juice for a professional bakery finish.
Ingredients
The Lemon Blondie Base
- 1 cup all-purpose flour
- 3/4 cup granulated sugar
- 1/2 cup unsalted butter, room temp
- 1 large egg, room temp
- 1 fresh lemon (zested and juiced to 1/4 cup)
- 1 cup fresh blueberries
- 1/4 tsp baking powder
- 1/4 tsp salt
The Royal Purple Glaze
- 1 cup powdered sugar, sifted
- 1 heaping tbsp frozen blueberries
- 2 tbsp fresh lemon juice
Instructions
Cream: Preheat oven to 350°F. Line an 8×8 pan with a parchment sling. Beat butter, sugar, and zest until fluffy. Mix in the egg.
Citrus: Stir in 1/4 cup lemon juice (mixture may look curdled).
Dry: Whisk flour, baking powder, and salt. Fold into wet ingredients until just combined.
Bake: Fold in fresh blueberries. Spread in pan and bake 25–30 mins until set. Cool completely.
Glaze: Pulse frozen berries and lemon juice; strain. Whisk 1 tbsp of this juice into powdered sugar. Spread over cooled bars and let set.
Notes
The Zest Secret: Rubbing lemon zest into sugar ruptures oil glands for maximum citrus aroma.
Frozen for Color: Frozen berries release deep purple pigments (anthocyanins) more easily because freezing breaks the cell walls.
The Sling Method: Use parchment overhang to lift the entire block out for clean, professional edges when slicing.
