In a large mixing bowl add the cake mix, water, oil, and eggs. Mix for 2-3 minutes with an electric mixer.

Add your cupcake liners into your muffin tins (cupcake pan).

Fill up 24 cupcake liners halfway up with the cupcake batter using a cookie scoop. Bake for 15-19 minutes. Use a toothpick to insert in the cupcake to make sure it is done and nothing is left on the toothpick.

Remove from the oven and allow to sit on a wire rack for 60 minutes or until completely cool.

In a separate large bowl add the butter. Beat on medium speed for 3-7 minutes. The longer you beat the fluffier your frosting will be.

Add the vanilla extract. Mix for 1-2 minutes on medium speed until fully incorporated.

Add half of the powdered sugar. Mix on medium speed for 3 minutes. Scrape the sides of the bowl. Add the remainder of the powdered sugar.

Add the milk 1 tablespoon at a time, if needed.

Add the green dye a toothpick amount at a time to the white frosting. Mix on medium speed. Keep adding more dye until you reach the green you want to achieve.

When ready, add your frosting tip such as a large round tip (can also use a large star tip) into your piping bag (pastry bag or ziplock bag works too) and then fill it with the green frosting.

Gently pipe your green icing starting from the inside on the top of the cupcake, working in a circular motion covering the outside of the cupcake.

Top off with a single red heart sprinkle for Grinch's heart.

Serve and enjoy these adorable Grinch cupcakes!
