Chocolate Marshmallow Peanut Butter Squares

Recipe from here

Ingredients
1 can (14 ounces) sweetened condensed milk
1 package (11 ounces) peanut butter and milk chocolate chips
1/2 cup milk chocolate chips
1/2 cup creamy peanut butter
1 teaspoon vanilla extract
1-1/2 cups miniature marshmallows
1 cup broken miniature pretzels
1 cup Rice Krispies

Instructions

• Place first 5 ingredients in a large heavy saucepan; cook and stir over low heat until smooth and blended, about 5 minutes (mixture will be very thick).
• Remove from heat; stir in remaining ingredients.
• Spread into lightly greased pan.
• Refrigerate (covered? I didn’t) until firm, ~3 hours. Cut into squares.

Notes:

• I tried 2 different pan sizes and neither were quite right. The mixture didn’t fill a 13x9-in. pan and it was quite thick in a 8x8-in. pan.
• For easier cutting / cleaning, I lined the pan with greased foil, letting the ends extend up the sides.
