After watching TeaV videos with Zack, I decided to blend my own version of this right down to the sprinkles. On the video, ratios were 60% Vanilla, 30% Cream, 10% Caramel. I went by weight rather than volume measure. Just added some sprinkles for color, and it works. I keep some amount of this on hand as long as I have the components to make it. The last batch I mixed had an excess of red sprinkles which can make the brewed tea color a little weird. If you blend your own, I recommend the pastel jimmies.
This does smell like a vanilla cupcake, and it makes a great dessert type tea with milk and sweetener. Great if you want to have your cake and avoid the calories.
