• Preheat oven to 325° F. Prepare mini muffin tins by lining with mini paper liners and/or spray generously with non-stick spray and then a dusting of cocoa-powder or flour. This is important so the cake bites don't stick.

For Cake

• Whisk the granulated sugar, flour, baking soda and salt together in a large bowl. Set aside.
• Combine butter, water and cocoa powder in a medium sauce pan, bring to a boil. Remove from heat then pour into the dry ingredients. Gently mix together. Fold in buttermilk and eggs. Blend well. Batter will be thin.
• Using a small 1 Tablespoon cookie scoop, place one scoop of batter in each mini muffin cup. Bake in preheated oven for 10 to 12 minutes. Remove from oven. (If liners were not used allow the bites to cool in the pan for 5 minutes, then gently remove by using the tip of a knife to release around the edges.) Place on wire racks to cool completely before frosting.

For Frosting

• In a medium sauce pan heat milk, butter and cocoa, over medium heat, until it comes to a boil. Remove from heat then whisk in powdered sugar and vanilla until smooth and no lumps remain. Carefully spoon a tablespoon of frosting over each bite. Frosting will set after a few minutes. Serve and enjoy!
