1 box yellow cake mix
3 eggs
1 cup milk

Use electric mixer on low to moisten the mixture. Once it is moistened, turn the mixer up to medium high and beat for 3 minutes. The batter will be very smooth and light and creamy.

In a separate bowl combine:

2 (10 ounce) packages completely thawed
    frozen strawberries
3 ounces strawberry flavored gelatin

Mix this up really well.

Spray a 9 x 13-inch baking pan with Pam Cooking Spray and then put 1 cup of miniature marshmallows and sprinkle them along the bottom of the pan. (You can use more to cover the pan if you wish.)

Spread the cake batter evenly over the marshmallows. You should be able to smooth out the batter without disturbing the marshmallows. The strawberry mixture goes on last. Do smooth it out gently with the back of a spoon. Bake in preheated oven at 350 degrees F for 50 minutes.
