Ingredients: 

1 cup pumpkin purée 

1/4 cup peanut butter 

1/4 cup milk 

3 cups old-fashioned oats, divided 

Directions: 

1. In the bowl of an electric mixer fitted with the paddle attachment, beat pumpkin puree, peanut butter, and milk on medium-high until well combined, about 1-2 minutes. Gradually add 2 1/2 cups of old-fashioned oats at low speed, beating just until incorporated. 
2. Using a small cookie scoop, roll the mixture into 1 1/4-to-1 1/2-inch balls, forming about 20. Dredge balls in remaining 1/2 cup old-fashioned oats, pressing to coat.
3. Cover and place in the refrigerator until firm, about 1 hour.
4. These can be kept refrigerated in an airtight container for up to 1 week.
