In a large bowl, add flour, sugar, unsweetened cocoa powder, salt, and baking powder. Mix it until everything is well-combined.
In a separate bowl, you will need to mix the wet ingredients. Add in the milk, vanilla extract, oil, and egg.
Take your handheld mixer and you're gonna mix it until it is light and fluffy.
Mix the wet and dry ingredients.
Take about a tablespoon of cupcake batter and place it onto your cupcake liners.
Grab your Ferrero Rocher and place it into the center of the cupcake.
Fill up the cupcake liners to about two-thirds full.
Pop into the oven and bake it for 15 to 20 minutes.
Once the cupcakes are done baking, cool them first because we are going to make the chocolate frosting.
