Instructions

Lemon Brownies

  • Preheat oven to 325°F. Spray a 9X9-inch square pan with baking nonstick spray. Line the bottom and 2 sides of the pan with parchment paper. Spray again.
  • In a small sauce pan, add the butter, (cut it into cubes first) and the white chocolate. Heat on medium-low heat until completely melted. Take off the heat.

  • In a medium bowl, sift the flour, cornstarch, and salt. Set aside.
    2 cups All-purpose flour, 1 tablespoon Cornstarch, 1 teaspoon Salt
  • Using a mixer, beat the sugar, eggs, and egg yolk on high-speed for 5 minutes. Add in the butter/ white chocolate mixer, oil, vanilla, lemon zest, and lemon juice. Mix on low until just combined.
    2 cups White granulated sugar, 3 Large eggs, 1 Egg yolk, ½ cup Oil, 1 teaspoon Pure vanilla extract, 3 Lemons zested, 2 tablespoon Lemon juice
  • Add in the dry ingredients and mix on low speed. Take off the mixer and scrape the bowl with a rubber spatula. Pour the batter into the pan.
  • Bake for 40-45 minutes until a toothpick inserted comes out with moist brownie crumbs. If it is a lot of raw batter, bake for another 2 minutes and check again.

Notes

Flour- Make sure flour is spooned and leveled or use a kitchen scale. Compacted flour can dry out the brownies and cause them to be cakey.
High altitude baking- Add an extra 1 tablespoon of flour.
Pull out dairy ingredients 2 hours before baking.
