homemade frosty paws

i found this recipe online last night, i honestly don't remember the website, i just googled homemade dog treats and this was on a site.  I probably won't make it until it gets warmer out, but miya loves the frosty paws and this seems really easy to make.
 
1 Qt. plain or vanilla yogurt
1 banana or 1 large jar banana baby food
2 Tbsp. peanut butter
2 Tbsp honey
2 Tbsp carob powder (optional)
 
If using regular banana, mash well.  Mix all ingredients until well blended (you can use a blender or food processor).  Place into ice cube trays or small bathroom sized cups and freeze once frozen you can store in freezer in plastic bag.  You can also add granola or anything else your dog likes.
