Pretzel Jello Cake?

I need a recipe to make a Pretzel Jello Cake.
The thing is my mother in law always makes a Pretzel Jello cake for my boyfriend and he loves them. Today I said to him I will make him a Pretzel Jello cake but I have no idea how the cake is made.
Can you let me know about a good recipe for cooking a Pretzel Jello cake?

You better make a good cake, your bf is going to compare your Pretzel Jello cake with his mom's.
I found a recipe for you:

PRETZEL JELLO CAKE

1 stick melted butter
1 1/2 c. crushed pretzels
1 (8 oz.) pkg. cream cheese
1 lg. container Cool Whip
1 c. sugar
1 (6 oz.) pkg. strawberry Jello
1 lg. pkg. frozen strawberries

Mix melted butter, pretzels, and 1/2 cup sugar together and press into 9 x 13 inch pan. Bake 6 minutes at 350 degrees. Dissolve Jello in 2 cups boiling water and add frozen strawberries. Let gel. Combine cream cheese, Cool Whip, and 1/2 cup sugar; put on top of crumbs. When Jello is starting to set, pour over cheese layer and refrigerate until firm.
