Preheat the Oven: Preheat to 350°F (175°C) and line a 9-inch square baking pan with parchment paper for easy lifting and slicing.

Cream the Butter and Sugar: Beat softened butter and sugar together until light and fluffy, about 2-3 minutes.

Add the Egg: Mix in the egg until fully incorporated.

Add Lemon Juice: Stir in fresh lemon juice; it may not completely incorporate but that’s fine.

Combine Dry Ingredients: In a separate bowl, whisk together flour, baking powder, and salt. Gradually add this to the wet ingredients and mix until just combined.

Fold in Strawberries: Gently fold in diced strawberries, avoiding over-mixing.

Spread the Batter: Transfer the batter to the prepared pan, smoothing it out evenly.

Bake the Blondies: Bake for 30-35 minutes, until the edges are golden and a toothpick comes out moist but not wet.

Cool: Let the blondies cool on a wire rack before glazing.

Prepare the Glaze: Puree fresh strawberries and strain to get about 1 tablespoon of strawberry puree. Whisk together the puree, sugar, and lemon juice.

Glaze the Blondies: Once cooled, spread the glaze over the blondies. Let it set for 10-15 minutes before slicing.
