I used espresso and really like the intense coffee flavor. I put it on brownies and thinned it out a bit and drizzled it on a coffee cake. Excellent!!!!
I made this to frost Kittencal Bass' Spiced Pumpkin-Applesauce Bars -- soooo good! When I saw the two recipes, I thought they might be interesting together. Everyone at work really liked it, even the skeptics who wrinkled their noses at the description of the dessert. I didn't have coffee already made, so I dissolved a 1/2 tsp. of instant in 2 tbs. of hot water. Worked for me! I had to add extra powdered sugar to thicken the frosting enough, but it tasted great! Really nice with the pumpkin-y flavor of the cake.
Yum. I'm a vegan, so in place of cream cheese and milk I used Tofutti "Better than Cream Cheese" and soymilk. The frosting was a little bit runny at first, but one it had been in the fridge for few minutes it firmed up.
