Ingredients

  • 1 pkg. yellow cake mix
  • 1/2 cup melted butter
  • 1 egg
  • 3 cups mini marshmallows
  • 1/4 cup butter
  • 1/2 cup light Karo syrup
  • 1 pkg. peanut butter chips
  • 2 cups Rice Krispies

Instructions

  1. Mix the yellow cake mix, melted butter, and egg together until well combined.
  2. Press the mixture into a greased baking pan and bake at 350°F (175°C) for 5 to 10 minutes.
  3. Remove from oven and sprinkle mini marshmallows evenly on top.
  4. Put the pan back in the oven until the marshmallows are puffy, not brown, about 2-3 minutes.
  5. Meanwhile, prepare the topping by melting 1/4 cup butter with 1/2 cup light Karo syrup.
  6. Stir in peanut butter chips until melted and smooth.
  7. Pour the peanut butter mixture over the marshmallows and cake base.
  8. Sprinkle rice Krispies over the top and press lightly to set.

Tips & Substitutions

For a richer flavor, consider using a butter cake mix instead of yellow. If you prefer a nutty taste, add chopped peanuts or almonds to the topping. To make the bars less sweet, reduce the amount of peanut butter chips slightly. Ensure the marshmallows are evenly spread for consistent texture across the bars. If you're short on time, pre-made caramel sauce can be a quick substitute for the butter and Karo syrup mixture.

Serving Suggestions

These bars are perfect for dessert or a sweet snack with coffee or tea. Consider serving them alongside a scoop of vanilla ice cream or with a drizzle of chocolate sauce for an indulgent treat. They also pair beautifully with a cup of warm Sugar-Free Holiday Nog for a festive touch. Cut into squares for easy sharing at parties or potlucks.

Storage & Reheating

Store leftover Salted Nut Roll Bars in an airtight container at room temperature for up to five days. If you want them to last longer, refrigerate them for up to two weeks. To reheat, place in the microwave for about 10-15 seconds to soften slightly before serving, which will help restore their chewy texture.

Frequently Asked Questions

Can I make this recipe gluten-free?

Yes, you can use a gluten-free yellow cake mix to adapt this recipe. Ensure all other ingredients are gluten-free as well, including the peanut butter chips and Rice Krispies. This way, you can still enjoy the delicious flavors without gluten.

What can I use instead of mini marshmallows?

If you don't have mini marshmallows, you can substitute with larger marshmallows cut into smaller pieces. Another option is to use marshmallow fluff, which can be spread evenly across the cake layer instead of using whole marshmallows.

How do I prevent the bars from sticking to the pan?

To prevent sticking, make sure to grease the baking pan thoroughly with butter or cooking spray. You can also line the pan with parchment paper, leaving some overhang, which makes it easier to lift the bars out after they cool. This ensures neat cuts and easier serving.
