So, we ended up making something for Ellen. I thought this would be a bit confusing to the girls since they only know her as Grandma, but we told the girls that her real name is Ellen which starts with an E, so they seemed fine with it. (Grandma said she was so happy that we didn't wait until Gg week!)
I found this recipe for an Eclair Cake. This cake is so simple to make with the kids and it is so yummy (just not so healthy!).
2 - 3.5oz boxes of vanilla pudding (we made our's with french vanilla and "Ellen's" with regular vanilla)
3 cups of milk
8oz Cool Whip, thawed
graham crackers (we used honey flavored ones)
1 can of chocolate frosting
Mix together pudding and milk. Fold in Cool Whip. Layer bottom of 9x13 baking dish with graham crackers. Spread half of the pudding mixture over graham crackers. Add another layer of graham crackers. Top with the remaining pudding mixture. Add another layer of graham crackers. Microwave the frosting for 30 seconds. Stir. Pour over the top layer of graham crackers. Spread with a spatula or knife to evenly coat the top of the graham crackers. (Andy said the chocolate was a bit much for him, so you could just drizzle it over top if you are not a big chocolate fan). Refrigerate for at least four hours before serving.
