Chocolate mayonnaise cake

Mix the all-purpose flour with the baking soda.

Pour hot water over the cocoa powder and let it bloom five minutes.

Add the mayonnaise, sugar, vanilla and salt to the cocoa and whisk until smooth, since mayonnaise is lumpy.

Add the flour mixture and fold gently just until no streaks remain; do not overmix.

Divide evenly between two buttered, lined pans.

Bake at 350F / 180C for around 35 to 40 minutes until firm in the middle.

Dollop buttercream on the first layer, add the second, dollop more on top and bring it down the sides; finish with sprinkles.
