FAQ

Can I use a different flavor of cake mix? Absolutely! White or vanilla cake mix works best for getting that bright green color, but you can also use yellow or even lemon cake mix for a fun twist.

How do I get the cake that perfect Grinchy green color? A few drops of green gel food coloring will do the trick! Start with a little and add more until you reach your desired shade of “Grinch green.”

Can I make this cake ahead of time? Yes! In fact, poke cakes often taste even better the next day since the pudding has more time to soak in. Just keep it covered and refrigerated until serving.

What if I don’t have red heart sprinkles? No problem! You can use red candy pieces, red sanding sugar, or even pipe small hearts with red icing—anything that adds that signature “heart grew three sizes” touch.
