Preheat the oven to 350 degrees F. and spray a donut pan with non-stick baking spray.
In a large bowl, whisk all dry ingredients together.
Purée the fresh strawberries and measure out 1/4 cup of the purée for the donut batter.
In a separate bowl, whisk all wet ingredients together until combined and smooth.
Combine the wet ingredients with the dry ingredients and whisk in the fresh strawberry purée.
Pour evenly into the donut pan molds, being careful not to overfill.
Bake for 15 minutes. Allow the donuts to cool completely on a wire rack while you make the glaze.
In a small bowl, stir together: powdered sugar, 1 tbsp of strawberry purée, 1 tsp of lemon juice, and the fresh lemon zest.
When donuts are cool, brush the tops of the donuts with glaze with a pastry brush and enjoy.
