Has anyone tried this in coffee

Yes, I use WF Choc and peppermint liquid stevia with my Starbucks VIA instant. It tastes like Starbucks Peppermint Mocha Latte (I know that's a stretch but it's good!). I gave up skim milk for IP. Within a short time I discovered this flavor combination and no longer miss the skim milk. After I phase off, I'm still not going to use milk in coffee. I will continue to save calories with WF products and stevia.

Another good one is to heat a mug of water and add WF Choc syrup and Peppermint liquid stevia or English Toffee liquid stevia, tastes like a fancy hot chocolate drink.

I have had the WF chocolate dip on the "chocolate cake mug" recipe and it was delicous but not in coffee yet, may have to try that!

I use the 1tbsp WF Carmel Dip, with my coffee and IP Vanilla Shake(mixed with 5oz water) to make my "vanilla latte" each morning!!! I love and I have had it everyday since starting 6 weeks ago! Not willing to give up my AM coffee.
