  1. Prepping Your Base:
    • Preheat your oven to 350°F (175°C).

Making the Crust (Optional): * In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Using a fork or your fingertips, mix well until the crumbs resemble wet sand and are evenly coated. * Press the crumb mixture firmly into the bottom of a 9×13-inch baking dish. * Bake for 10 minutes. Remove from the oven and let the crust cool completely before adding the filling.

Using a Pre-Made Crust (Shortcut): * For a time-saving option, you can absolutely use a store-bought graham cracker crust. * Just ensure the pre-made crust fits snugly into your 9×13 inch baking dish. No need to pre-bake this crust.

  1. Crafting the Butterscotch Filling:

    • In a medium saucepan, whisk together the heavy cream, brown sugar, butter, and dark corn syrup over medium heat.
    • Heat the mixture constantly, whisking regularly, until the sugar dissolves, and the mixture reaches a gentle simmer.
  2. Tempering the Egg Yolk:

    • In a separate small bowl, whisk together the egg yolk and cornstarch until you have a smooth mixture.

Here’s the Key Step: * Slowly whisk the egg yolk mixture into the simmering butterscotch mixture. This process is called tempering the egg yolk, which prevents it from scrambling when added to hot liquids. * Continue whisking constantly and vigorously until the filling thickens considerably and begins to bubble.

  1. Flavor Boost and Cooling Down:

    • Remove the saucepan from the heat and stir in the vanilla extract and salt.
  2. Assembling the Dessert:

    • Pour the hot butterscotch filling over the cooled crust (whether homemade or store-bought).
    • Let the filling cool completely at room temperature for at least 2 hours. This allows the filling to set properly.
    • Alternatively, for a faster set, you can refrigerate the entire baking dish for a couple of hours.
  3. Whipped Cream Topping (Optional):

    • If you desire a delightful finishing touch, whip up the topping!
    • In a chilled bowl (important to keep the cream cold), use an electric mixer to whip the heavy cream, powdered sugar, and vanilla extract together until stiff peaks form.
    • Gently spread the whipped cream evenly over the chilled butterscotch layer.
  4. Slice and Enjoy!

    • Cut your masterpiece, the Butterscotch Custard Monster Bar, into squares and savor the deliciousness!

Tips for How to make butterscotch custard monster bar

  • Brown Sugar Magic: For a more intense butterscotch flavor, consider using dark brown sugar instead of light brown sugar in the filling.
  • Corn Syrup Options: If dark corn syrup isn’t readily available, you can substitute it with light corn syrup or even maple syrup.
  • Whipped Cream Perfection: To prevent the whipped cream topping from becoming runny, ensure your cream is very cold before whipping.
  • Topping Extravaganza! Feel free to unleash your creativity with toppings! Chopped nuts, sprinkles, or a drizzle of caramel sauce can add another layer of flavor and texture.


  • Can I use a pre-made graham cracker crust? Absolutely! This is a great time-saving option. Just ensure the pre-made crust fits your 9×13 inch baking dish and doesn’t require pre-baking.
    • How long will this dessert keep? The Butterscotch Custard Monster Bar can be stored in an airtight container in the refrigerator for up to 3 days. The cold temperature helps the custard filling maintain its texture and prevents spoilage.

    • Can I freeze this dessert? Yes, you can freeze the entire assembled bar for up to 2 months. Freezing is a great option for enjoying this dessert later or if you need to make it ahead of time. Here’s how to freeze and thaw effectively:

      • Freezing: Once the Butterscotch Custard Monster Bar is completely chilled and set (at least 2 hours), cut it into squares. Wrap each square individually in plastic wrap and then place them in a freezer-safe container or zip-lock bag. Ensure the container is labelled with the date for easy reference.
      • Thawing: When ready to enjoy, transfer the frozen squares to the refrigerator and thaw overnight. You can also thaw them at room temperature for a few hours, but be mindful not to leave them out for extended periods to avoid bacterial growth.
    • Is this recipe difficult to make? No, this recipe is very beginner-friendly! It requires minimal baking experience and follows a straightforward process. Even if you’re new to baking, you can easily create this delicious dessert with these detailed instructions.

    • What are some variations I can try? This recipe offers room for creativity! Here are some ideas to explore:

      • Chocolate Chip Twist: Add ½ cup of semi-sweet chocolate chips to the hot butterscotch filling before pouring it over the crust. The chocolate chips will melt and create pockets of chocolatey goodness throughout the bar.
      • Peanut Butter Delight: For a peanut butter twist, drizzle some melted peanut butter over the top of the chilled butterscotch layer before adding the whipped cream (if using).
      • Boozy Infusion (for Adults Only): If you’d like to add an adult twist, consider incorporating a tablespoon of your favorite liquor, like bourbon or rum, into the butterscotch filling while it simmers on the stove. Just be sure to avoid letting the alcohol boil off completely.
    • Can I use a different type of milk or cream? While the recipe uses heavy cream for both the filling and the optional whipped cream topping, you can substitute some of it with other milk options depending on your preference and dietary needs. Here’s a breakdown:

      • For the Filling: Using full-fat milk instead of heavy cream in the filling will result in a lighter consistency. However, the filling might not set as firmly. You may need to adjust the cornstarch quantity to achieve the desired texture.
      • For the Whipped Cream: You can use heavy whipping cream, whipped cream alternative, or even chilled coconut milk to make the whipped cream topping. Keep in mind that the coconut milk will have a distinct flavor compared to traditional whipped cream.

    With these detailed FAQs and variations, you’re all set to conquer the delightful world of Butterscotch Custard Monster Bars!
