Monster Chocolate Cupcakes for Halloween

Combine milk and vinegar in a bowl. Let stand until milk curdles about 5 minutes.

Preheat oven to 350 degrees F (175 degrees C). Grease a 12-cup muffin tin or line cups with paper liners.

Combine 1/2 cup butter white sugar and vanilla sugar in a large bowl; beat with an electric mixer until smooth and creamy. Add eggs one at a time beating well after each addition.

Mix 3/4 cup plus 1 tablespoon flour cocoa powder baking powder baking soda and salt in a bowl. Alternate adding flour mixture and curdled milk to the creamed butter mixture mixing until batter is well blended. Spoon batter into the prepared muffin cups filling each 3/4 full.

Bake in the preheated oven until tops spring back when lightly pressed and a toothpick inserted in the center of 1 cupcake comes back clean about 14 minutes. Cool in the muffin tin for a few minutes then transfer to a wire rack to cool completely about 1 hour.

Combine cream cheese and 1/4 cup butter in a bowl; beat with an electric mixer until well combined. Mix in vanilla extract. Stir in confectioners' sugar gradually. Color frosting green with a few drops of food coloring.

Place green frosting in a pastry bag fitted with a grass tip. Hold the pastry bag at a 90-degree angle 1/8 inch above the surface of a cupcake. Squeeze bag to form green 'fur' by pulling tip up and away when the icing strand is about 1/2 inch high. Repeat to cover cupcake evenly with fur. Add 2 eyes to each cupcake.
