Preheat oven to 350 degrees.

Spray three 9-inch cake pans with nonstick spray or butter, then lightly coat with flour. Set aside.

Prepare cake mix according to package directions.

Measure batter, then divide it into 3 equal portions in 3 separate bowls.

Add varying amounts of food coloring to each bowl to create light, medium, and dark pink batter.

Transfer batter to cake pans and bake until a toothpick inserted in the center comes out clean, about 10 to 12 minutes.

Remove cake pans from oven. Let cool stightly, then remove cake layers from pans and transfer to a wire rack to cool completely.

While cake is cooling, chop chocolate into pieces and place in a small bowl. Microwave 20 seconds at a time, stirring well in between, until chocolate is melted.

Transfer chocolate to a piping bag fitted with a small round tip or a zip top bag with the corner snipped off.

Using a 2.5-inch circle cutter as a width guide, write the words you'd like to use on a piece of paper, then slide the paper into a zip top bag. Place the bag on a baking sheet (or another flat surface).

Trace over the words with the melted chocolate.

Transfer the baking sheet to your freezer to harden the chocolate.

Once the cake layers have cooled completely, use the 2.5-inch cutter to cut each cake layer into 7 circles.

Cover a dark colored circle generously with frosting, then add a medium colored circle, and add more frosting. Finish with a light colored layer, topping with more frosting.

Use the flat side of a knife to remove excess frosting from the sides of the cake.

Carefully push the chocolate words into the frosting on the cake tops.

Serve cakes immediately or store in a cool place. Enjoy!
