To make the cake, Heat the oven to 350°F and grease a 9-inch cake pan with cooking spray or brush it with olive oil and line with parchment paper.
In a large bowl, whisk the water, vanilla, vinegar, olive oil and sugar until smooth. Sift the flour, cocoa powder, soda and salt over the bowl and whisk again until almost smooth. A few lumps are okay.
Transfer to the prepared pan and bake for 25 to 35 minutes, until a toothpick inserted into the center of the cake comes out with a moist crumb or two.
Make the glaze while the cake cools.
Combine all of the glaze ingredients in a small bowl and stir with a fork until smooth, adding more olive oil and/or more sugar until you have a thick, spreadable glaze.
Spread the glaze on the cake and generously decorate with rainbow sprinkles.
