Preheat the oven to 350°F (175°C). Grease and flour a cake pan.

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

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In a separate bowl, combine the flour, baking powder, and salt. Gradually add to the creamed mixture alternately with milk.

Pour the batter into the prepared cake pan and smooth the top.

Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Allow to cool.

In a mixing bowl, beat the softened butter until creamy.

Gradually add the powdered sugar, alternating with milk, until the desired consistency is reached.

Mix in the vanilla extract and divide the frosting into separate bowls for coloring.

Add food coloring to create green, brown, and blue frostings.

Once the cake is completely cool, spread a layer of frosting on top and around the sides.

Use the colored frostings to create a Minecraft design on the cake.

Top with Minecraft-themed candies for decoration.
