Key Lime Eclair Cake, layers of creamy filling bursting with key lime flavor between graham crackers, topped with vanilla frosting. Tastes just like a key lime pie, but much easier!
Whip cream cheese in a large bowl with a hand mixer until creamy. Whip in the sweetened condensed milk until combined. Slowly add the key lime juice until combined. Fold in the whipped topping.
Take a 9x13 inch pan and place a layer of graham crackers. Spread 1/3 of the key lime mixture on top. Repeat two more times. Add the remaining graham crackers on top.
Place frosting with the top off and foil wrapper is taken off completely into the microwave. Microwave for 30 seconds, until frosting is pour-able. Pour evenly over the cake. Spread with a spatula to cover the entire top. Cover with plastic wrap and refrigerate for 4 hours, up to overnight. Serve and enjoy!!
