In a pinch

I ran out of coffee creamer this morning. I can't drink my coffee black and I can't just skip my caffeine intake.

Luckily, I had some whipping cream in the fridge leftover from a dessert I had  made just last week. 

In a pinch heavy whipping cream makes a great (although higher calorie) substitute for low fat coffee creamer.

What kind if quick substitutes have you used in a pinch?
