Not giving you enough notice, but this is a great recipe for Cinco de Mayo!
1 boxed white cake mix
3 egg whites
3/4 cup bottled margarita drink mix
1/2 cup water
1/3 cup vegetable oil
1 container Cool Whip
1 tablespoon tequila (optional)
2 tablespoons lime juice (fresh or bottled) (if using fresh, zest the lime and add that too!)
Preheat the oven to 350 degrees F. Spray a 9x13 pan with cooking spray, and flour it. (if using the spray for baking, omit the flouring).
In a large bowl, combine the cake mix, egg whites, drink mix, water, and oil, and mix for 1-2 minutes on medium until smooth. Pour into prepared cake pan.
Bake for 25 minutes or until a toothpick comes out clean.
Mix the tequila and lime juice into the Cool Whip until combined, and use to frost the cake once it has cooled.
Store in the refrigerator.
My review: Yum! This tasted really good, and the margarita flavor wasn't overwhelming like I thought it would be. Make without the tequila if you're having an underage crowd, or people who won't enjoy the taste.
