Preheat your oven to 350°F and spray a 9×13 baking dish with nonstick spray.

In a large bowl, whisk together the dry stuff: flour, sugar, cocoa powder, baking soda, and salt.

Make one big well and two small ones in the dry mix. (It’s a quirky trick, but it works!)

Add vinegar in one small well, vanilla in the other, and oil in the big one.

Pour water over everything in the bowl and stir until fully combined.

Bake for 30–35 minutes, or until a toothpick comes out clean.

Cool completely before frosting. Optional: After cooling, instead of frosting, dust with powdered sugar if that’s what you have on hand.
