Preheat the oven to 350 degrees. Put a parchment paper circle in the bottom of two 8 inch cake pans. Spray the parchment and the sides of the cake pans and set aside.

In a large bowl combine the butter and sugar and mix until well combined.

Stir in the eggs and vanilla and mix well.

In a medium bowl combine the flour, cocoa powder, baking powder, baking soda, and salt. Mix well.

Add half of the flour mixture to the butter mixture and mix well. Stir in the milk and mix until combined. Stir in the remaining flour mixture.

Divide the batter between the two prepared pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Remove from oven and cool for 10 minutes. Remove from pan and cool completely on a write rack.

To make the frosting put the butter, 2 cups of powdered sugar, vanilla, and 2 tablespoons of milk in a bowl. Mix with a mixer on medium speed until smooth. Add in the remaining powdered sugar a half cup at a time until desired consistency is reached. Add in more milk if needed.

Remove 1/4 of the frosting from the bowl. Divide that quarter of frosting into 3 bowls. Dye one red, one pink, and one mauve (or a color in between the red and pink).

Use 1/2 cup of the white frosting and frost one layer of the cake. Put the second layer on top of it. Use remaining white frosting to frost the cake.

Pipe pink hearts around the sides of the cake. Pipe a mauve heart underneath each pink heart. Then pipe a red heart underneath each mauve heart.

If you have any remaining white frosting pipe a pretty edge on top of the cake. Sprinkle with heart sprinkles or colored sprinkled.
