Mars Bar Rice Bubble Slice

A Mars Bar Rice Bubble Slice Recipe. A delicious no bake treat that would be great for afternoon snacks or for party food for a child’s birthday

Thank you to my friend Mel for sharing this Mars Bar Rice Bubble Slice recipe with me.  She made this at Christmas time for her kids and it looked so yummy I had to try. I wouldn’t add these to the kids lunch boxes as the chocolate can cause a mess in their lunch boxes and on their hands and faces.  However, they would be good as an after school snack.  I used a silicone muffin tray to make these, and they popped out so easily once it had set, plus the added bonus of no slicing needed!

What size mars bars and chocolate melts we are in Canada sizes would be great, thanks.

You could basically set any slice into individual muffin sizes. I set cheese cake in muffin tins. Great idea that is. My eldest is finally off to preschool this year, and I’m liking that idea. Tomorrow is my cooking day. I best fine my mini muffin tins

Great idea, I might find a nice cheesecake recipe and give a try 🙂

A couple of weeks ago I made Mars Bar Slice (think it was same recipe as this but without the extra choc) – for a change I just put spoonfuls into small truffle patty cases and sprinkled with 100’s and 1000’s then set in fridge. The kids loved them and they were a good snack size for a treat.

That’s a cute idea, I had some today and cut off the choc tops, was still really yummy without the chocolate.

Hi what I did what put them in the long skinny ice cube trays and they were not messy at all. I just added some wrapped up for school lunch and it was great 🙂
