Ingredients for Oatmeal Peanut Butter Protein Balls

Here’s everything you need to make around 12-14 protein balls:
- 1 cup old-fashioned oats (gluten-free if needed)
- ½ cup peanut butter (or any nut butter of your choice)
- ¼ cup protein powder (vanilla or chocolate flavor works well)
- 2 tbsp honey or maple syrup (for sweetness)
- 2 tbsp ground flaxseed or chia seeds (optional, for extra fiber)
- 1 tsp vanilla extract (optional, for flavor)
- ¼ cup milk (any type of milk works, adjust to desired consistency)

Prep in Minutes – No Baking Required
Preparing these Oatmeal Peanut Butter Protein Balls is as easy as it gets. In a large mixing bowl, combine the oats, protein powder, ground flaxseed (or chia seeds), and a pinch of sea salt. Then, add the peanut butter, honey, vanilla extract, and milk. Stir everything together until fully combined and the mixture reaches a dough-like consistency. If the mixture feels too dry, add a bit more milk, one tablespoon at a time, until it holds together. Once the mixture is ready, use a tablespoon to scoop it out and roll it into balls with your hands.
Place the rolled balls onto a tray lined with parchment paper and refrigerate them for at least 30 minutes to let them firm up. Once chilled, they are ready to enjoy! These protein balls will last for up to a week in the fridge, making them perfect for meal prep.

No-Bake Method for a Quick, Healthy Snack
Why the No-Bake Method Works
The no-bake method makes these protein balls so convenient. You don’t need to turn on the oven, which means less mess and a quicker prep time. The key to making these protein balls work without baking is ensuring that the ingredients bind together well. The oats, peanut butter, and protein powder create the perfect texture, and the honey or maple syrup provides just the right amount of sweetness. By chilling the mixture, the protein balls firm up and hold their shape, making them easy to pack for travel or grab as a snack when you’re in a rush.
How to Store Your Oatmeal Peanut Butter Protein Balls
Once your protein balls are firm, transfer them to an airtight container and store them in the fridge. They’ll stay fresh for up to a week, making them great for meal prep. If you want to make a larger batch, you can also freeze them for up to 3 months. To thaw, simply take them out of the freezer the night before and let them sit in the fridge overnight. These protein balls are perfect for busy weeks when you need a quick, nutritious snack.
