Preheat the oven to 350 degrees and grease a small loaf pan or divide batter into four mini cake molds.

Whisk the flour, granulated sugar, and baking powder in a mixing bowl.

Add the softened butter, egg, milk, and 1 teaspoon vanilla extract. Stir until the batter is smooth.

Pour the batter into the prepared pan or molds and bake for 20 to 25 minutes until a toothpick comes out clean. Let the cakes cool completely.

Beat the cream cheese with the powdered sugar and remaining teaspoon of vanilla extract until the mixture is creamy and spreadable.

Spread a thin base layer of cream cheese frosting over each cooled cake.

Spoon the remaining frosting into a piping bag or zip-top bag with a small corner cut. Pipe short, overlapping strips across the cakes to create the mummy bandage effect.

Press two candy eyes onto each cake while the frosting is still soft.
