Prepare Cake Batter: Divide the white cake mix into four bowls, adding a different food coloring to each. Mix until vibrant and uniform.

Bake Cupcakes: Pour each colored batter into cupcake tins, filling them about 2/3 full. Bake in a preheated oven at 350°F for 15-20 minutes, or until a toothpick inserted comes out clean. Allow cupcakes to cool completely.

Crumble Cupcakes: Once cooled, gently crumble each cupcake into separate bowls.

Pipe Frosting: Fill a piping bag with your chosen white frosting and pipe beautiful swirls.

Layer in Jars: Start layering by spooning a layer of crumbled cake into the jars, followed by a swirl of piped frosting. Alternate layers until jars are filled, finishing with frosting on top.

Decorate Jars: Add edible grass, jelly bean eggs, or sprinkles on top of the frosted layer.

Serve: Present the jars either chilled or at room temperature.
