Grinch-Themed White Chocolate Pudding Cake

Instructions:
Prepare the cake:
Preheat the oven according to the instructions on the white cake mix box.
In a large mixing bowl, prepare the white cake mix following the directions on the box. Add the required eggs, oil, and water.
Once the batter is mixed, divide it in half. Add green food coloring to one half of the batter to achieve a vibrant green color. Leave the other half plain or add a drop or two of red food coloring for a Grinch-themed contrast.
Pour the green batter into a greased 9×13 baking dish and bake according to the time indicated on the cake mix box. Set aside to cool.
Prepare the white chocolate pudding:
While the cake is cooling, prepare the instant white chocolate pudding by whisking the pudding mix with 2 cups of milk in a medium bowl. Set aside to thicken for a few minutes.
Make the buttercream frosting:
In a large mixing bowl, use an electric mixer to beat the softened butter until creamy.
Gradually add powdered sugar, 1 cup at a time, mixing on low speed until combined.
Increase the speed to medium-high and beat until light and fluffy, about 3-4 minutes. If desired, add a small amount of green food coloring to the frosting to give it a festive hue.
Assemble the cake:
Once the cake has cooled completely, spread the prepared white chocolate pudding evenly over the entire cake.
Using a piping bag or a spatula, spread or pipe the buttercream frosting on top of the pudding layer, creating smooth, even coverage.
Decorate the cake:
Decorate the cake with heart-shaped sprinkles and green sprinkles for a fun and festive Grinch-themed touch.
