Peanut Butter Marshmallow Squares Recipe

This old fashioned peanut butter marshmallow squares recipe was often used by my Aunt Sylvia McIlmoyle to make yummy treats for family occasions. She wrote out the no bake dessert recipe and gave it to Mom who found it to be one of the best recipes for dessert squares she had ever tried.

These dessert squares are quick and easy to make, and they never fail to turn out delicious. The golden-colored treats look as though you spent hours making them, but only you will know the truth. This recipe's a keeper, folks! You will use over and over again!

Peanut Butter Marshmallow Squares

Caution: Aunt Sylvia's homemade dessert squares are sinfully delicious, and you won't be able to stop eating them! Just saying.

Ingredients:

1/2 cup butter
1/2 cup peanut butter
12 ounces butterscotch chips
3 cups miniature marshmallows

Directions:

Mix butter, peanut butter, and butterscotch chips in a double boiler just until melted, then remove from heat. Spread 3 cups miniature marshmallows in a buttered 9x13-inch pan. Carefully pour melted mixture over marshmallows. Place in refrigerator and cut in squares when cool. It's that easy. It's that delicious!

Save a few chips and marshmallows to decorate the top, or be generous and add extra.

If you cannot obtain miniature marshmallows, you could try using sliced large marshmallows instead. Use 10 large marshmallows to replace each cup of the miniature kind.

Substitute chocolate chips for the marshmallow to make Peanut Butter Chocolate Squares, if preferred. Yummy!

Butterscotch Marshmallow Squares

This old fashioned peanut butter marshmallow squares recipe is one that a friend of Mom's sometimes used, so I included it for you to try as a comparison to Aunt Sylvia's recipe, but I still think hers is better. See what you think.

1/2 cup butter
3/4 cup peanut butter
One package (10 ounce / 283 gram) of butterscotch chips

Melt above ingredients together slowly. Don't let mixture get too hot.

After it cools a little, stir in one bag (10.5 ounce / 297 grams) of miniature colored marshmallows. Place mixture in buttered 8-inch or 9-inch square pans.

Set in cool place and allow to get firm. Cut into squares or bars. —Doris Northey

Squares Make Fond Memories

For me, sharing this brings back fond memories. The top photo was taken in October 1979, on the occasion of my parent's 40th wedding anniversary.

It shows my Aunt Sylvia cutting a pan of her delicious squares while being carefully watched by our eldest son Peter who was hoping to get the biggest piece. And he did!
