Ingredients

  • 12 oz. milk chocolate or semi-sweet chocolate chips
  • 1/2 cup margarine or butter flavored Crisco
  • 1/2 to 1 cup creamy or chunky peanut butter
  • 1 pound miniature marshmallows

Instructions

  1. Combine chocolate chips, margarine, and peanut butter in a heavy saucepan.
  2. Put on low heat and melt the mixture.
  3. Cool partly so marshmallows don't melt when added.
  4. Add marshmallows and stir until all are coated and combined.
  5. Pour the mixture into a greased 9 x 13-inch pan or cookie sheet.
  6. Place in the refrigerator to cool and set.
  7. When cold, cut into bars and store in the refrigerator or a cool place.

Tips & Substitutions

For a creamier texture, consider using creamy peanut butter, but chunky adds a nice crunch. If you want a richer taste, try substituting half of the chocolate chips with dark chocolate. Keep an eye on the melting process to prevent burning; stir frequently and remove from heat once melted. Using a greased spatula can help when spreading the mixture in the pan.

Serving Suggestions

These no bake marshmallow bars are perfect as a sweet treat for gatherings or a quick dessert after dinner. They pair beautifully with a glass of cold milk or a scoop of vanilla ice cream. For a fun twist, consider adding crushed nuts or drizzling caramel on top before serving. They also make a great snack alongside a fruit salad.

Storage & Reheating

Store leftover marshmallow bars in an airtight container in the refrigerator for up to one week. If they are too hard after being chilled, let them sit at room temperature for a few minutes before cutting. For longer storage, you can freeze them in a freezer-safe container for up to three months.

Frequently Asked Questions

Can I use different types of chocolate chips?

Yes, you can absolutely use dark chocolate or even white chocolate chips if you prefer. Each type will give a different flavor profile to the bars, so feel free to experiment based on your taste preferences.

What can I do if my mixture is too thick?

If your mixture becomes too thick to easily mix in the marshmallows, you can gently reheat it on low while stirring. Alternatively, adding a small amount of peanut butter or melted butter can help loosen it up.

How do I cut the bars without making a mess?

To cut the bars cleanly, use a sharp knife that has been warmed with hot water. Wipe the knife between cuts to ensure clean edges, and consider refrigerating the bars again for a short time if they are too sticky.
