High-Protein Overnight Oats with Peanut Butter Ingredients

3 pitted Medjool dates, chopped
1¾ cups unsweetened soy milk
1½ cups old-fashioned rolled oats
1 cup whole-milk plain strained (Greek-style) yogurt
¼ cup smooth natural peanut butter

How to Make High-Protein Overnight Oats with Peanut Butter

In a blender, combine the chopped dates, soy milk, oats, yogurt, peanut butter, vanilla extract, and salt. Blend until the oats are smooth and the dates are fully broken down, which should take about 1–2 minutes.
Transfer the blended mixture to a medium bowl and stir in the chopped chocolate. Be sure the chocolate is evenly distributed.
Divide the mixture evenly among four 8- to 10-ounce jars or containers. Seal tightly with lids and refrigerate for at least 8 hours or up to 4 days.

Note: Use scissors instead of a knife to chop dates for easier cleanup. For garnish, sprinkle a bit of chopped chocolate on top before serving.

Lower calorie: Reduce the chocolate to 1 ounce and opt for low-fat Greek yogurt.
Higher protein: Add a scoop of unflavored or vanilla protein powder before blending.
