Preheat your oven to 350 °F (175 °C). Line 2 muffin pans with 24 liners.
In a large bowl, stir together the sugar (if using honey, don’t add it yet), flour, cocoa, baking powder, baking soda and salt.
2 cups (400 grams) granulated sugar, 1 3/4 cups (236 grams) flour, 3/4 cup (85 grams) cocoa powder, 1 teaspoon baking powder, 1 teaspoon baking soda, 1 teaspoon salt
Add eggs, milk, honey (if using), oil and vanilla. Mix until combined and then stir in the boiling water. The batter will be almost as thin as water.
2 large eggs, 1 cup (240 ml) milk, 1/2 cup (120 ml) oil, 2 teaspoons vanilla extract, 3/4 cup (177 ml) boiling water
Fill each liner just a little more than halfway full.
Bake for 18 minutes or until a toothpick comes out with some moist crumbs, but no liquid.
Let cool for 5 minutes in the pans, and then, turn out onto a rack to cool. Let cool completely, about an hour, before frosting.
