Ingredients

  • 1/2 cup butter or margarine
  • 3/4 cup sugar
  • 2 eggs
  • 1 teaspoon vanilla
  • 3/4 cup flour
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder
  • 1/2 cup ground nuts
  • 2 tablespoons cocoa
  • 2 cups miniature marshmallows
  • 1 cup chocolate chips
  • 1 cup creamy peanut butter
  • 1 1/2 cups Rice Krispies

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9 x 13-inch pan.

  5. Spread the batter evenly in the prepared pan.
  6. Bake for 15 minutes, then remove from oven.

  8. Return to oven and bake for an additional 3 minutes until marshmallows are slightly melted.

Tips & Substitutions

For a richer flavor, consider using dark chocolate chips instead of semi-sweet. If you don't have ground nuts, you can substitute with oats or leave them out entirely for a nut-free version. Ensure your butter is softened to room temperature for easy creaming with sugar. A pinch of espresso powder can enhance the chocolate flavor if desired.

Serving Suggestions

These bars make a delightful dessert on their own but can be served with a scoop of vanilla ice cream for added indulgence. Pair them with a glass of cold milk or a hot cup of coffee for a perfect afternoon treat. They also make a great addition to potlucks or as a sweet snack to accompany meals like the Chili Cocktail Pie.

Storage & Reheating

Store leftover Double Chocolate Crumb Bars in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate them for up to a week. To reheat, place individual bars in the microwave for about 10-15 seconds until warm and slightly gooey.

Frequently Asked Questions

Can I use a different type of nut in this recipe?

Absolutely! Feel free to experiment with different nuts like walnuts, pecans, or almonds, based on your preference or what you have on hand. Just make sure to chop them finely for even distribution throughout the bars.

What can I use instead of peanut butter?

If you're looking for a nut-free alternative, you can use sunbutter or a similar seed butter. For a different flavor profile, try using almond butter or cashew butter, keeping in mind that the taste will vary slightly.

How can I tell when the bars are done baking?

The bars are done baking when the edges are set and slightly golden, and the center feels firm but not overly hard. After adding the marshmallows, they should be melted but not browned. Allowing them to cool will also help them firm up a bit more.
