Preheat the oven to 350°F (175°C).

In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition.

Stir in the milk and vanilla extract.

In a separate bowl, combine the flour, baking powder, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Divide the batter evenly into prepared cake pans.

Bake in the preheated oven for 30 minutes or until a toothpick inserted in the center comes out clean.

Allow the cakes to cool completely before frosting.

For the frosting, beat together the softened butter and powdered sugar until fluffy.

Add 2 tablespoons of milk and 1 teaspoon of vanilla extract, mixing until well combined.

Divide the frosting into three bowls and color each with food coloring (green, brown, and blue).

Frost the cakes using the colored frostings to create a Minecraft-themed design.

Decorate with Minecraft-themed candies.
