Place dates and 1 1/2 cups of water in a microwave-safe bowl. Microwave on high for 10 minutes, pause microwave to stir dates after 5 minutes. Water should no longer be visible when time is up; if water remains, microwave dates for 2-5 more minutes. Mash dates into a smooth paste.

While waiting for dates, coarsely grind peanuts using a food processor or blender. Add crushed peanuts and remaining ingredients to a large mixing bowl.

Add date paste to peanut butter mixture. Using a large spoon to combine, fold the ingredients in from the edges while rotating the bowl. Towards the end of mixing, you may find it easier to use your hands*.

Portion dough into two dozen ~1/4 cup balls. Gently roll the dough portions between your hands to form golf ball sized treats.

Place balls in a single layer in food storage containers. Seal containers (for easy stacking) and refrigerate for 2 hours before serving.
