Easy, 5-ingredient Christmas Rice Krispie treats that look like The Grinch! No gelatine needed!
Line an 8x10-inch tin with baking paper and set aside.
Over low heat, melt the vegan butter in a pan.
Add the mini marshmallows and stir gently until melted. Vegan marshmallows don't melt the same as ones with gelatine in them, so don't be alarmed if it clumps together.
Add the food colouring and gently stir it in until you get your desired colour.
Pour the melted marshmallow mixture into a large bowl with the crispy rice cereal and mix well until evenly coated.
Transfer this mixture to your lined tin and press in firmly. Using the bottom of a cup is great for this.
While the mixture is still sticky, place the Skittles on top, in 4 rows of 3.
Leave to set for 1 hour, remove from the tin and cut into squares. If you like, you can make heart Grinch Rice Krispie treats by using a heart-shaped cookie cutter.
