Tasty cookies will be a perfect wedding favor, and you can easily make some yourself! The supplies are 1 box of rice krispies, 1 pack of marshmallows, 2 tbsp of butter, 1/2 tsp of red food coloring, 1 large bar of white chocolate, sprinkles for decoration, a heart shaped cookie cutter. Add your marshmallows and butter into a bowl and microwave for 2 minutes. Remove the bowl, mix well and heat for another minute. Gradually mix in 3 cups of rice Krispies. Mix well until all the moisture has been soaked up. Spread the mixture out on a baking tray and flatten to about an inch thick and leave to cool. Cut out shapes with the heart shaped cookie cutter. Set aside to cool for a little and break your white chocolate up into squares and place in a heatproof bowl. To finish the cookies, look here.
