This is the icing recipe I used:
1 stick of butter (softened)
1/3 cup of Mountain Dew
1/4 tsp. vanilla extract
1/4 tsp. lemon extract
Add powdered sugar (about 1 cup at a time) until you get the consistency you like. I am guessing that I used 5-7 cups. I know...not too exact. But I had a 2 pound bag and I almost used all of it!
Green Food Coloring
*I also colored some sugar with green food coloring and sprinkled it on top*
I made this cake to take to a pool party, and everyone who tried some said they really liked it! It was tasty. If you like lemon flavored desserts, you will like this cake!
