How to Make Mars Bar Squares

Step 1: Prepare Your Baking Pan

Lightly grease an 8×8 inch (20×20 cm) square baking pan so that your squares can be easily removed later.

Step 3: Combine with Rice Krispies

Once the mixture is smooth, turn off the heat. Stir in the Rice Krispies, making sure they are well coated with the melted mixture.

Common Mistakes to Avoid

When making Mars Bar Squares, it’s easy to make a few common mistakes. Here are some tips to ensure your treat turns out perfectly.

Not Greasing the Pan: Failing to grease the baking pan can lead to sticky squares that are hard to remove. Always lightly grease your pan before adding the mixture.
Overheating the Butter: Melting butter on too high heat can cause it to separate. Use low heat and stir gently to keep the mixture smooth.
Skipping the Whisking Step: If your butter and chocolate bars separate, you may end up with a lumpy texture. Remove from heat and whisk until smooth for a perfect blend.
Using the Wrong Rice Cereal: Not all rice cereals are created equal. Make sure to use Rice Krispies or Rice Bubbles for the right texture.
Not Letting It Set: Cutting into the squares too soon can ruin their structure. Allow them to sit at room temperature for at least 2 hours before slicing.
