I spray a large cereal bowl with pam and then add the hot chocolate mix, a 1/4 scoop of protein powder (I believe the recipe called for a scoop of super chocolate from MRC, but it was too expensive to I improvise with the powder I bought from walmart), one spenda packet and 3 tablespoons of water. Mix well and microwave for 1 minute. It rises quite a bit in the microwave, but then flattens down.
Sometimes I add vanilla, orange or even rum extract.
