I thought this PIN looked good and wanted to try it.
Since I wanted to do it before I got groceries and the Pin said you could use milk I did that.
So I used 2% milk and since she said it wouldn't be as creamy with milk I added 2 heaping spoonfulls of greek yogurt.
My verdict on using this with milk and greek yogurt. 1) it's not creamy, it's like the crystally 'ice milk' consistency. 2) I can taste the bitterness of the cocoa.
I was thinking I may try this again with greek yogurt and honey so that you don't taste the bitterness of the cocoa as much.
