Really Easy and Good Cornflake Mars Bar Squares (No Bake)

I can almost taste the summer evenings of my childhood just thinking about these squares. My grandma, a master of effortless deliciousness, would whip up a batch of these on sweltering days when turning on the oven was simply out of the question. The gooey sweetness, the satisfying crunch, and the way the chocolate melted in your fingers as you ate them outside – pure bliss. They were the perfect treat, and I’m thrilled to share the magic with you.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 5 minutes (for melting ingredients)
• Total Time: 20 minutes (plus chilling time)
• Yields: 1 (13×9-inch) pan
• Dietary Type: Vegetarian

Ingredients

• 3/4 cup margarine
• 4 (2 1/2 ounce) Mars bars, cut into chunks
• 6 cups corn flakes, crushed
• 1 1/4 cups semi-sweet chocolate chips
• 3-4 tablespoons butter

Equipment Needed

• 13 x 9-inch baking pan
• Large pot or large microwave-safe bowl
• Spatula or spoon

Instructions

1. Begin by preparing your 13 x 9-inch baking pan. You can lightly grease it with cooking spray or line it with parchment paper for easier removal of the finished squares.

2. In a large pot or a large microwave-safe bowl, partially melt the margarine. If using the stovetop, do this over low heat. If microwaving, use short bursts of 30 seconds to prevent burning. You don’t want it completely melted at this stage.

3. Add the Mars bar pieces to the partially melted margarine. If using the stovetop, melt the mixture over low heat, stirring constantly until everything is smooth and well combined. If using the microwave, continue to melt in 30-second intervals, stirring between each interval, until the Mars bars are fully melted and the mixture is smooth. Be careful not to overheat the chocolate, as it can seize and become grainy.

4. Add the crushed corn flakes to the melted Mars bar mixture. Mix thoroughly until the corn flakes are completely coated with the gooey mixture. Ensure that every flake gets its fair share of the Mars bar coating.

5. Press the corn flake mixture firmly and evenly into the prepared baking pan. A flat-bottomed measuring cup or your clean hands can help achieve a smooth and compact layer. The firmer the base, the better the squares will hold their shape.

6. In a separate microwave-safe bowl, combine the chocolate chips and butter. Microwave in 30-second intervals, stirring after each interval, until the chocolate chips and butter are completely melted and smooth. Stir well to ensure a glossy finish. Watch carefully to prevent burning. Alternatively, melt in a heatproof bowl set over a pan of simmering water (a double boiler), stirring occasionally until smooth.

7. Spread the melted chocolate evenly over the corn flake mixture in the pan. Use a spatula or the back of a spoon to create a smooth, even layer.

8. Place the pan in the refrigerator and chill for at least 1-2 hours, or until the squares are firm and the chocolate has set.

9. Once set, cut the squares into desired sizes and serve!

Expert Tips & Tricks

• Crushing the Cornflakes: Don’t just toss the cornflakes in whole! Gently crush them – you want a mixture of sizes. Some whole flakes add texture, while smaller pieces bind everything together. You can do this by hand in a large zip-top bag or gently pulse them in a food processor.
• Melting the Mars Bars: Patience is key here! Low and slow is the way to go to avoid scorching the mixture. If you’re using the microwave, keep a close eye on it and stir frequently.
• Pressing Firmly: Pressing the cornflake mixture into the pan is crucial for structural integrity. The firmer you press, the less likely the squares will crumble when you cut them.
• Even Chocolate Layer: For a professional-looking finish, try swirling the melted chocolate with a toothpick or skewer to create a marbled effect.

FAQs (Frequently Asked Questions)

Q: Can I use a different type of candy bar instead of Mars bars?
A: Absolutely! Snickers, Milky Way, or any similar chocolate-caramel bar would work well.

Q: My chocolate layer is cracking when I cut the squares. How can I prevent this?
A: Make sure the chocolate layer isn’t too thick. Also, let the squares sit at room temperature for a few minutes before cutting them to soften the chocolate slightly.

Q: Can I make this recipe without a microwave?
A: Yes, you can melt the margarine and Mars bars in a pot over low heat on the stovetop, stirring constantly. You can also melt the chocolate and butter in a double boiler.

Q: How do I prevent the cornflakes from becoming soggy?
A: Ensure that you don’t over-melt the margarine and Mars bars mixture. You want it to be just melted enough to coat the cornflakes. Also, press the mixture firmly into the pan to create a compact base.

Q: Can I add sprinkles to the top?
A: Of course! Add sprinkles immediately after spreading the melted chocolate so they adhere properly.
