Here’s how you make them:
Form peanut butter sandwiches with Ritz crackers.
Place them in the bottom of each cup of a muffin tin.
In a large bowl beat together 16 oz cream cheese, 1/2 cup sugar.
Then add 1/2 cup peanut butter, 1/2 cup sour cream, 1 tsp vanilla, 2 eggs, and beat again.
Pour mixture over each peanut butter sandwich until each cup is 3/4 full.
Top with crushed Ritz cracker.
Bake for 22 minutes at 275°F.
Let cool completely and then refrigerate 2 hours.
