How to make a Cappuccino Frappe

Okay when my grandma took me to Starbucks for the first time I asked for a White Chocolate Mocha and she ordered me a White Chocolate Mocha Frappuccino. I tasted it and I feel in love instantly. When I told dad about my new craving he was upset that the drink was so expensive. So this Christmas my dad got my mom a nice blender, and it hit me, "Why should pay so much for a drink that I could make in my home for just the price of the coffee I use.
So with a little experimenting and previous knowledge of blended drinks I have come up with a recipe that is equal (and in my opinion is better) than name brand.  

Step 1 Your Cofffee

Okay since the goal here is to save money, don't go and use Starbucks coffee. I mean if that is what you use regularly than do, but I like Dunkin Donuts.
Okay here is the ratio I use to make this drink.
1  part double strength coffee
2 parts ice
So if you use 1 cup of coffee use two cups of ice
1 cup of coffee is enough for two people, for a single serving I use 6 oz. of water and two Tbsp. of coffee grounds and 12 oz of ice
