| Unsweetened almond milk | 2 cups | Moisture, creaminess | |

Step-by-Step Instructions
Preparation Phase
1. Preheat your oven to 375°F. While it’s heating, spray your 8-inch square baking dish with cooking spray, ensuring all surfaces are lightly coated to prevent sticking.
Mixing Phase
2. Combine dry and wet ingredients in a large mixing bowl. Add:
- Old fashioned rolled oats
- Vanilla protein powder
- Salt
3. Add liquid and binding ingredients:
- Unsweetened almond milk
- Peanut butter
- Eggs (or flax eggs if vegan)
- Maple syrup
- Melted coconut oil
- Vanilla extract
Mix thoroughly with a spatula or wooden spoon until all ingredients are evenly incorporated. The mixture should be uniform with no dry pockets of oats or protein powder.
Baking Phase
4. Fold in blueberries gently to avoid crushing them. Reserve a small handful for topping.
5. Pour mixture into your prepared baking dish and spread evenly. Top with additional fresh blueberries for visual appeal and bursts of flavor throughout.
6. Bake for 35-40 minutes until the center is set but still slightly moist. The edges should pull away slightly from the pan, and a toothpick inserted in the center should come out mostly clean with just a few moist crumbs.
Finishing Touches
7. Cool for a few minutes before portioning. This allows the oatmeal to set properly for clean slices.
8. Portion and serve each piece with a generous drizzle of your favorite nut butter for extra creaminess and protein.
