Ingredients

  • 1/4 cup butter
  • 1 egg
  • 1 cup flour
  • 1 teaspoon baking powder
  • 18 marshmallows
  • 1 cup brown sugar
  • 1 teaspoon vanilla
  • 1/4 teaspoon salt
  • 1/2 cup chopped nuts

Instructions

  1. Cream butter, brown sugar, and egg well.
  2. Add vanilla and beat thoroughly.

  4. Spread the mixture in a greased 8-inch square pan and bake at 350°F for 30 minutes.

  6. Return to oven for about 2 minutes, or until marshmallows are softened.

Tips & Substitutions

For a richer flavor, try using brown butter instead of regular butter. If you're looking for a nut-free option, you can simply omit the chopped nuts or substitute with sunflower seeds for a similar crunch. To enhance the butterscotch flavor, consider adding a pinch of butterscotch chips to the batter. Make sure to evenly spread the marshmallows to ensure each bite is gooey and sweet.

Serving Suggestions

These Butterscotch-Marshmallow Squares are delightful on their own but pair beautifully with a scoop of vanilla ice cream for an indulgent dessert. For a festive touch, serve them alongside Aunt Tollie'S Fruitcake during holiday gatherings. They can also be enjoyed with a cup of coffee or tea for a sweet afternoon snack.

Storage & Reheating

Store leftover squares in an airtight container at room temperature for up to three days. If you want them to last longer, you can refrigerate them for up to a week. To reheat, place a square in the microwave for about 10-15 seconds for a warm, melty treat, or enjoy them chilled for a different texture.

Frequently Asked Questions

Can I use different types of nuts in this recipe?

Absolutely! While the recipe calls for chopped nuts, you can use walnuts, pecans, or even almonds based on your preference. Just make sure to chop them into small pieces to ensure even distribution throughout the squares.

What can I use instead of marshmallows?

If you can't find marshmallows or prefer a healthier option, you can substitute them with chopped dried fruit like apricots or figs. This will give a different texture and flavor, but it will still add sweetness to the squares.

Can I make this recipe gluten-free?

Yes, you can easily make these squares gluten-free by substituting all-purpose flour with a gluten-free flour blend. Just make sure your baking powder is also gluten-free to ensure the entire recipe is suitable for those with gluten sensitivities.
