Preheat your oven to 350°F (175°C). This ensures that your blondies will bake evenly.
Line your 9x9 inch baking pan with parchment paper or grease it lightly with olive oil to prevent sticking.
In a mixing bowl, whisk together the sifted all-purpose flour, sugar, salt, and baking soda until well combined.
In another bowl, combine the dairy-free yogurt, olive oil, fresh lemon juice, and lemon zest. Mix until smooth and well blended.
Add the eggs to the wet mixture and whisk until everything is combined.
Pour the wet ingredients into the dry ingredients and gently fold them together using a spatula. Be careful not to over-mix.
Spoon the batter into your prepared baking pan, spreading it evenly with your spatula.
Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The edges should be lightly golden.
Remove the blondies from the oven and let them cool in the pan for about 10 minutes. Transfer to a wire rack to cool completely.
Prepare glaze by mixing powdered sugar, lemon zest, and fresh lemon juice until smooth. Drizzle over the cooled blondies for a delightful finish.
