Importance of Each Tool

• Medium saucepan: Essential for melting the butter and Mars bars without burning them.
• Heatproof bowl: Perfect for melting chocolate chips safely in the microwave.
• Spatula: Helps to mix ingredients thoroughly and press down the mixture evenly in the baking pan.

Ingredients

For the Base

• 1/2 cup unsalted butter
• 4 53 gram Mars bars (chopped)
• 3 cups Rice Krispies (aka Rice Bubbles)

For the Topping

• 1 cup milk chocolate chips (or chopped milk chocolate)

How to Make Mars Bar Squares

Step 1: Prepare Your Baking Pan

Lightly grease an 8×8 inch (20×20 cm) square baking pan to prevent sticking.

Step 2: Melt the Butter

Add the unsalted butter to a medium saucepan over low heat.

Step 3: Melt the Mars Bars

Once the butter is melted, add the chopped Mars bars. Gently stir as they begin to melt until smooth. If they start separating, take off heat and whisk until combined.

Step 4: Combine with Rice Krispies

Turn off the heat and stir in the Rice Krispies. Mix until evenly coated.

Step 5: Transfer to Pan

Spoon the mixture into your prepared pan. Press it down gently but firmly. If it sticks, use a lightly greased spatula or non-stick cooking spray on your hands.

Step 6: Melt Chocolate for Topping

In a heatproof bowl, combine milk chocolate chips. Microwave on medium power in 45-second intervals, stirring each time until almost melted. Stir until smooth.

Step 7: Add Chocolate Layer

Spread the melted chocolate evenly over the top of your Rice Krispie mixture.

Step 8: Set and Slice

Let sit at room temperature for about 2 hours or until hardened before slicing into squares.

Common Mistakes to Avoid

Making Mars Bar Squares can be a delightful experience, but a few common mistakes can ruin your treat. Here’s how to sidestep them.

• Ignoring the Butter Temperature: Using cold butter may not melt properly, leading to clumps. Always use unsalted butter at room temperature for a smooth blend.
• Overheating the Chocolate: If you microwave the chocolate too long, it can burn. Heat in short bursts and stir frequently for perfect melting.
• Not Pressing Firmly Enough: Failing to press down the mixture can result in crumbly squares. Make sure to pack it tightly in the pan for better structure.
• Skipping the Cooling Time: Cutting into the squares too soon can lead to messy pieces. Allow sufficient time for the chocolate to set before slicing.
• Using Different Rice Cereal: Substituting Rice Krispies with other cereals may change the texture and flavor. Stick with Rice Krispies for best results.
