Pippa's English Measurements Cake Batter Rainbow Rice Krispies Treats Recipe
3 Tablespoons Butter
280g Marshmallows (I used mini ones and medium sized ones as that's what I had)
4oz Sponge Cake Mix
100g Rice Krispies
50g Rainbow Drops (I may have over sprinkled and used closer to 60g)
1 Teaspoon Vanilla Extract
Grease a 9inch Square Pan and Mix the Rice Krispies and Rainbow Drops.
Melt the butter in a large saucepan over a low heat and add the marshmallows.
Let the marshmallows melt and add in the cake mix a spoonful or two at the time.
Add the Vanilla Extract and then mix in the Rice Krispies and Rainbow Drops until it is all covered in the melted butter/marshmallow/vanilla mix
Sprinkle in some sprinkles and mix it around before pressing into the baking tray and scattering some more sprinkles on top. I found it was better to leave more for the top than sprinkling in as they seemed to melt. Maybe English Sprinkles aren't as good as American ones?!
Leave the mixture and tray to set for at least thirty minutes. I put mine in the fridge, but I don't think that you have to do that.
Once set cut into squares and store in an air tight container with heavy noisy things on top so that everyone will know you are sneaking a piece because they are really addictive and you might not be able to stop at one.
The original recipe that I adapted mine from is at Gimme Some Oven.
