Equipment

Measuring cups round ¼ cup measurement
Large cookie scoop optional
Sheet pan or cookie sheet

Ingredients

▢ 4 Mars bars 52 grams each
▢ ½ cup butter
▢ 2 ½ cups crispy rice cereal (Rice Krispies)

US Customary - Metric

Instructions

Line a cookie sheet with parchment paper. Set aside.
Unwrap the Mars bars and place them in a microwave-safe bowl along with ½ cup of butter.
Heat in the microwave for 1 minute, then stir well to combine. If the chocolate bars are not completely melted heat for an additional 30 seconds. Stir until the butter and chocolate mix together easily.
Add 2 ½ cups of crispy rice cereal to the bowl and fold it in using a silicone spatula. Continue to mix it until the cereal is coated with the melted chocolate mixture.
Use a ¼ cup measuring cup or large cookie scoop to portion the mixture into discs.
Place each disc on the parchment-lined baking sheet and press down on them gently to form a traditional “cookie” shape. To prevent sticking I like to use the bottom of a measuring cup that has been lightly greased with cooking spray or butter.
Place the cookie sheet in the fridge to chill for 1 hour, or until set.
Serve once the cookies have set. Keep leftovers in the fridge.

Notes

Storage: Store any leftover Mars Bar Cookies in an airtight container in the fridge for up to 5 days. For extended storage, transfer them to freezer bags and freeze them for up to 3 months.

Stovetop method: Heat the butter and Mars bars in a double boiler or heavy-bottomed large saucepan until completely melted. Add the cereal to the melted mixture and form into cookies as per the recipe.
