Ingredients

  • 1 1/2 lb. white chocolate
  • 1 1/2 c. unsalted peanuts
  • 2 1/2 c. Rice Krispies
  • 3/4 c. crunchy peanut butter
  • 1/2 c. mini marshmallows

Instructions

  1. Mix together the white chocolate, peanuts, rice Krispies, peanut butter, and mini marshmallows.
  2. Pour the mixture into a greased 9 x 13-inch pan.
  3. Chill until set.
  4. Cut into bars and serve.

Tips & Substitutions

For a smoother texture, ensure the white chocolate is melted gently to avoid seizing. If you prefer a nut-free version, substitute the peanuts with sunflower seeds. You can also use almond butter instead of crunchy peanut butter for a different flavor. Consider adding a pinch of sea salt to enhance the sweetness of the chocolate. To customize, mix in dried fruits or swap Rice Krispies for a different cereal.

Serving Suggestions

Yum Yum Bars are perfect as a sweet treat for parties or packed lunches. They pair beautifully with a glass of cold milk or can be served alongside Classic Popcorn Balls for a fun snack spread. For a festive touch, drizzle melted chocolate over the bars before serving or sprinkle with colorful sprinkles.

Storage & Reheating

Store leftover Yum Yum Bars in an airtight container at room temperature for up to a week. If you live in a warm climate, refrigerate them to prevent melting. To reheat, briefly microwave a bar for about 10-15 seconds to soften it, but avoid overheating, which can change the texture.

Frequently Asked Questions

Can I use dark chocolate instead of white chocolate?

Yes, you can substitute dark chocolate for white chocolate to create a richer flavor. Keep in mind that the bars will be less sweet, so you may want to adjust the amount of peanut butter or marshmallows to balance the taste.

How can I make these bars vegan?

To make Yum Yum Bars vegan, use a dairy-free white chocolate alternative and substitute peanut butter with a vegan-friendly brand. Ensure the marshmallows are also vegan, as many contain gelatin. This way, you can enjoy a delicious plant-based version of this treat.

Can I freeze Yum Yum Bars?

Absolutely! You can freeze Yum Yum Bars for up to three months. Wrap them tightly in plastic wrap and then place them in an airtight container. To enjoy, simply thaw them in the refrigerator or at room temperature before serving.
