Instructions

1. If using fresh strawberries, toss diced berries with cornstarch (and optional sugar). Spread on a paper towel for 10–15 minutes to reduce moisture.

2. Preheat oven to 350°F (175°C). Line an 8×8 pan with parchment.

3. Whisk melted butter and brown sugar until glossy.

4. Add egg, vanilla, lemon zest, lemon juice, and sourdough discard. Mix until smooth.

5. In another bowl, whisk flour, baking powder, and salt.

6. Add dry ingredients to the wet mixture and stir just until combined.

7. Fold in fresh prepared or freeze-dried strawberries.

8. Spread batter into the pan.

9. Bake 28–34 minutes, until edges are lightly golden and the center is set (slightly glossy is fine).

10. Cool completely before slicing.

Notes

Loading...

For the most reliable texture, freeze-dried strawberries prevent all sogginess.

Fresh berries must be small-diced + cornstarch-coated to avoid wet spots.

Do not increase lemon juice; it will affect the blondie structure.

Variation ideas:

Add ½ cup white chocolate chips for extra sweetness.

Add ½ tsp almond extract for a bakery-style twist.

Swirl 2–3 oz softened cream cheese into the top for a cheesecake blondie.

Replace 2 tbsp flour with 2 tbsp coconut flour for a subtle coconut flavor (absorbs moisture).

Add 1–2 tbsp crushed freeze-dried strawberries to the batter for more berry intensity without extra liquid.
