I found this recipe online and changed it a little bit to my taste. The best thing, it takes only 5 minutes to make it. You can add sweeteners like honey, maple syrup, or dates. The sweetness of butternut squash is perfectly sufficient for me.
Here is my version:
2 tbsp rolled oats
2 tbsp coconut flakes ( I use unsweetened )
2 tbsp peanut butter
2 tbsp cooked butternut squash ( could be canned)
1/2 tsp cocoa powder
1/2 tsp vanilla
Process the ingredients in a food processor to make a paste. Roll 6 balls and cover them with cocoa powder, coconut, or grated walnuts, if you wish.
