What You Need

You need just 4 basic main ingredients that you probably already have in your kitchen to make this no-bake rice bubble slice!

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

For The Base

• Butter - either unsalted butter or salted butter. I recommend using butter rather than margarine.
• Milk chocolate - I like to use baking melts or cooking chocolate as they melt easier than regular chocolate.
• Golden syrup - this helps hold the slice together as well as adding a sweetness to the slice. You can replace the golden syrup with corn syrup, honey or maple syrup. 
• Rice Bubbles - also known as Rice Krispies, you can use any other brand of puffed rice cereal if you prefer.

For The Topping

• Milk chocolate - or dark chocolate.
• Coconut oil - or use a mild vegetable oil. This ingredient is optional, however it helps to prevent the chocolate topping from cracking when cut into slices.
• Sprinkles - for decorating (optional).

Equipment Required 

You don't need any fancy equipment to make this chocolate slice, just:

• Slice tin - 18cm x 22cm (7" x 9") rectangular tin
• Microwave safe bowl or Thermomix.
• Serrated knife - for cutting the slice.

Step By Step Instructions

This no bake chocolate slice takes just 10 minutes to prepare, then leave in the fridge to firm up!

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.

Step 1 - Melt The Butter, Chocolate And Golden Syrup

Grease and line a slice tin and place to one side.

Place the butter, milk chocolate and golden syrup in a microwave safe bowl.

Place in the microwave on medium power and heat in 30 seconds burst, stirring each time, until melted.

Step 2 - Add The Rice Bubbles

Add the Rice Bubbles to the bowl.

Stir Rice Bubbles into the chocolate mixture until thoroughly coated.

Step 3 - Press Mixture Into The Tin

Press mixture very firmly into the prepared tin. 

Note: It's important to press the mixture firmly into the tin so that it holds together when cut into pieces. Use a jug or round glass to press down firmly.

Step 4 - Make The Topping And Refrigerate

Place the milk chocolate and coconut oil, if using, in a microwave safe bowl. Microwave on 50% power until just melted, stirring every 30 seconds or so with a metal spoon. 

Once smooth, spread the melted chocolate over the slice, decorating with sprinkles if using. Place in the fridge and chill until firm, a minimum of 3-4 hours is recommended.

Step 5 - Cut The Slice

Remove the slice from the refrigerator about 30 minutes before cutting into squares, using a warm serrated knife.

Expert Tips

• Use a fresh box of Rice bubbles or Rice Krispies - this will ensure your slice is crispy and crunchy!
• If you don't want to use a microwave - you can also melt the chocolate and butter mixture in a saucepan on a low heat.
• Press the mixture VERY firmly into a greased and lined baking tin - the mixture needs to be pressed down very firmly so that it doesn’t break apart when you cut it.
• Chilling time - leave in the fridge to set for a minimum of 3-4 hours (overnight is best).
• Cutting the slice - take the slice out of the fridge 30 minutes before cutting to allow the chocolate to soften slightly. Use a small serrated knife to cut through the chocolate layer and then through the Rice Bubbles layer. For more tips on cutting slices see my detailed post on how to cut the perfect slices.
• Storing - chocolate rice bubble slice can be stored in an airtight container in the fridge for up to 1 week.
