Yes, tasty -- but it takes a little getting used-to.  You have to like coconut to like this snack item.  That taste quite overwhelmed all else, for me.  I found few chocolate chips -- maybe they were all taking a rest when my snacks were baked.  Anyway, it's a chewy but tasty item worthy of your consideration.  Give it a try.

The name of this coffee is Mahogany, in my mind a deep rich brown. The coffee flavor is deep and rich, and the color is dark brown. It is delicious.

I bought one of these thinking I would try it out and go back for more if it worked out.  They are cute, but I won't be buying more.  The Stay-Fresh Baby Food containers are MUCH better and cheaper.  The Stay-Fresh containers each hold 2 ounces and can go straight in the microwave.  Once the food is frozen I find it difficult sometimes to get the portion of food out of the Beaba container.  Not the best design and totally overpriced.
