• Heatproof bowl
• 8×8 inch (20×20 cm) square baking pan
• Spatula

Importance of Each Tool

• Large saucepan: Ideal for melting the butter and Mars bars evenly without burning them.
• Heatproof bowl: Perfect for melting chocolate safely in the microwave without risk of damage.
• Spatula: Helps in mixing ingredients smoothly and pressing down the mixture firmly into the 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. This will help prevent the squares from sticking once set.

Step 2: Melt Butter

Add the butter to a large saucepan and gently melt over low heat. Stir occasionally until fully melted.

Step 3: Add Mars Bars

Add the chopped Mars bars to the melted butter. Gently stir as they begin to melt together.

Step 4: Create a Smooth Mixture

Continuously stir until smooth. If separation occurs, remove from heat and whisk until combined.

Step 5: Mix in Rice Krispies

Once melted, turn off the burner and stir in the Rice Krispies until evenly coated.

Step 6: Press into Pan

Spoon the mixture into the prepared pan. Press it down gently using a greased spatula or non-stick spray on your hands if needed.

Step 7: Melt Chocolate Topping

Place chocolate chips or chopped chocolate in a heatproof bowl. Microwave on medium power in 45-second intervals, stirring each time until smooth.

Step 8: Finish and Set

Spread the melted chocolate over the top of the rice krispie base. Let sit at room temperature for about 2 hours or until set before slicing into squares.

How to Perfect Mars Bar Squares

To achieve the best texture and flavor in your Mars Bar Squares, follow these simple tips.

• Use fresh ingredients: Ensure your Mars bars and chocolate are fresh for maximum flavor.
• Melt slowly: Melt butter and chocolate over low heat to prevent burning and ensure a smooth mixture.
• Press firmly: When pressing the mixture into the pan, ensure it’s compact. This helps the squares hold their shape when cut.
• Cool completely: Allow the squares to cool at room temperature until fully set before slicing for clean edges.
• Store properly: Keep leftover squares in an airtight container at room temperature or in the fridge to maintain their freshness.

Best Side Dishes for Mars Bar Squares

Mars Bar Squares can be enhanced by pairing them with complementary side dishes. Here are some great options:

1. Fruit Salad: A light fruit salad adds freshness and balances the richness of the bars.
2. Cheese Platter: Include mild cheeses like brie or cheddar for a savory contrast.
3. Chocolate Fondue: Dip pieces of Mars Bar Squares into warm chocolate sauce for an extra indulgent treat.
4. Mini Muffins: Serve alongside blueberry or banana muffins for variety in texture and flavor.
5. Coffee or Tea: A warm cup of coffee or herbal tea can enhance your dessert experience.
6. Yogurt Parfait: Layer yogurt with granola and fruits for a delightful, creamy side dish that complements the bars.

Common Mistakes to Avoid

Making Mars Bar Squares is easy, but there are common mistakes that can affect the outcome of your treat.

• Not Greasing the Pan: Failing to grease your baking pan can make it difficult to remove the squares later. Always lightly grease your pan to ensure easy removal.
• Overheating Ingredients: Melting the butter and chocolate too quickly can cause separation. Use low heat and stir continuously for a smooth mix.
• Using Stale Rice Krispies: Using stale or old Rice Krispies can affect the crunchiness of your bars. Ensure your cereal is fresh for the best texture.
• Skipping Cooling Time: Not letting the chocolate layer cool completely can result in messy squares. Patience is key; allow ample time for setting.
• Not Pressing Firmly Enough: If you don’t press the mixture into the pan firmly, your bars may crumble. Use a spatula or greased hands to pack them down well.
