Tin Roof Sundae Bars: A Sweet Slice of Nostalgia

My earliest memory of a Tin Roof Sundae involves a sticky summer afternoon, a vintage ice cream parlor with spinning stools, and the sheer joy of that first bite. The cool vanilla, the rich chocolate sauce, and the salty crunch of peanuts – it was pure magic. This recipe for Tin Roof Sundae Bars captures that same delightful combination in an easy-to-make treat that’s perfect for sharing… or not!

Recipe Overview

• Prep Time: 12 minutes
• Cook Time: 32 minutes
• Total Time: 44 minutes
• Yields: 36 bars
• Dietary Type: Not specified

Ingredients

• 1 (22 ½ ounce) package deluxe brownie mix
• ½ cup very hot water
• ½ cup oil
• 1 egg
• 1 (7 ounce) jar marshmallow cream
• 1 ½ cups salted peanuts
• 6 1/16 ounces milk chocolate candy bars, broken

Equipment Needed

• 13×9 inch baking pan
• Large bowl
• Spoon
• Oven

Instructions

1. Preheat your oven to 350°F (175°C).
2. Lightly grease the bottom only of a 13×9 inch baking pan. Greasing only the bottom helps the bars release cleanly without overly browning the sides.
3. In a large bowl, combine the 22 ½ ounce package of deluxe brownie mix, ½ cup of very hot water, ½ cup of oil, and 1 egg.
4. Using a spoon, beat the mixture for 50 strokes. This is important to properly incorporate the ingredients without overmixing. Overmixing can lead to a tough brownie.
5. Spread the brownie batter evenly into the prepared pan. Make sure to get into all corners of the pan.
6. Bake for 30 minutes.
7. Remove the pan from the oven and immediately spread the 7 ounce jar of marshmallow cream evenly over the warm brownie base. Work quickly, as the residual heat will help the marshmallow cream spread smoothly.
8. Sprinkle 1 ½ cups of salted peanuts generously over the marshmallow cream layer. Press them down gently so they adhere slightly.
9. Arrange the broken pieces of 6 1/16 ounces of milk chocolate candy bars evenly over the peanut layer.
10. Return the pan to the oven for 2 minutes, or until the chocolate is completely melted. Keep a close eye on it to prevent burning.
11. Remove the pan from the oven and carefully spread the melted chocolate evenly over the peanuts and marshmallow cream, creating a smooth chocolate topping. Use an offset spatula for the neatest results.
12. Allow the bars to cool completely in the pan before cutting. This is crucial for clean cuts and preventing the bars from falling apart. You can speed up the cooling process by placing the pan in the refrigerator for an hour.
13. Once cooled, cut into 36 bars. Use a sharp knife and wipe it clean between each cut for the best presentation.

Expert Tips & Tricks

• Elevate Your Brownie Base: For an even richer brownie base, consider using melted butter instead of oil. You can also add a teaspoon of vanilla extract or a tablespoon of instant espresso powder to the batter for enhanced flavor.
• Perfectly Melted Chocolate: If you’re concerned about burning the chocolate in the oven, you can melt the chocolate in a double boiler or microwave it in 30-second intervals, stirring in between, until smooth. Then, spread the melted chocolate over the peanut and marshmallow layer instead of baking it.
• Salty-Sweet Balance: Don’t be afraid to experiment with different types of salted nuts. Pretzels, chopped pecans, or even a sprinkle of sea salt on top of the chocolate layer can add a delightful salty-sweet contrast.
• Marshmallow Magic: For a toasted marshmallow flavor, you can lightly torch the marshmallow cream layer with a kitchen torch before adding the peanuts and chocolate. Be careful not to burn it.
