1 box strawberry cake mix
1/3 cup canola oil
white chocolate chips, optional
1 cup powdered sugar
1 1/2 tablespoons milk
1/2 teaspoon vanilla extract
Preheat oven to 350º F and line a 9-inch square baking dish with parchment paper, leaving a 2-inch overhang on both sides.
In a large bowl or mixer, beat eggs and canola oil into cake mix until no lumps remain.Note: if using chocolate chips, fold them in now.
Pour batter into lined baking dish and smooth out the top.
Bake for 15-17 minutes, or until toothpick inserted in center comes out mostly clean.
Remove brownies from oven and let cool 5 minutes before extracting parchment paper from baking dish and transferring to a wire rack.
In a medium bowl, whisk milk and vanilla extract into powdered sugar until smooth.Note: for a thicker glaze, use less milk; for a thinner glaze, more milk.
Drizzle glaze over the slightly cooled brownies and let set before cutting into squares and serving.
