Emergency Chocolate Cake - flour

Method

• Adjust an oven rack to the middle position and heat the oven to 350 egrees. Lightly coat an 8-inch square cake pan with vegetable oil spray.
• Whisk the flour, sugar, cocoa, and baking soda together in a large bowl. In a separate bowl, whisk the mayonnaise, water, and vanilla together. Stir the mayonnaise mixture into the flour mixture until combined.
• Scrape the batter into the prepared pan and smooth the top. Bake until a wooden skewer inserted into the center of the cake comes out with a few crumbs attached, 35 to 40 minutes.
• Let the cake cool in the pan on a wire rack, 1 to hours. Cut into squares and serve straight from the pan or turn the cake out onto a serving latter and dust with confectioners' sugar (if desired).
