Whether you’re trying to eat healthier, build muscle, or simply find a new breakfast idea that isn’t boring, this recipe is going to become a staple in your kitchen. In this guide, you’ll learn everything about making high protein baked oatmeal: from the best ingredients to variations and storage tips.
Why Choose High Protein Baked Oatmeal?
Protein is essential for muscle repair, appetite control, and stable energy levels. While oats are naturally a good source of fiber and complex carbs, they’re not high in protein on their own. By adding ingredients like protein powder, Greek yogurt, eggs, or nut butter, you can transform a simple oatmeal dish into a protein-packed breakfast that keeps you full for hours.
Some key benefits include:
- Keeps you full longer – Protein slows down digestion, preventing mid-morning hunger crashes.
- Supports muscle growth – Perfect for active lifestyles, workouts, and recovery.
- Convenient meal prep – Bake once, enjoy for days.
- Versatile flavors – From chocolate peanut butter to apple cinnamon, the options are endless.
Ingredients for High Protein Baked Oatmeal
Here’s a base recipe that’s easy to adapt.
Dry Ingredients:
- 2 cups rolled oats (old-fashioned, not instant)
- 1 scoop (about 25–30g) vanilla or unflavored protein powder
- 1 tsp baking powder
- ½ tsp ground cinnamon
- Pinch of salt
Wet Ingredients:
- 1 ½ cups milk (dairy or unsweetened almond milk)
- ½ cup Greek yogurt (adds creaminess and extra protein)
- 2 large eggs
- 3 tbsp maple syrup or honey
- 1 tsp vanilla extract
Optional Add-ins:
- 2 tbsp nut butter (peanut, almond, or cashew)
- ½ cup fresh or frozen berries
- ¼ cup chopped nuts or seeds
- ¼ cup dark chocolate chips
Step-by-Step Instructions
- Preheat oven – Set your oven to 350°F (175°C). Grease or line an 8×8-inch baking dish with parchment paper.
- Mix dry ingredients – In a large bowl, stir together oats, protein powder, baking powder, cinnamon, and salt.
- Whisk wet ingredients – In another bowl, combine milk, Greek yogurt, eggs, maple syrup, and vanilla until smooth.

- Transfer to baking dish – Spread the mixture evenly in the prepared pan.
- Bake – Bake for 30–35 minutes, or until the top is golden brown and a toothpick inserted comes out clean.
- Cool and slice – Let it cool slightly before slicing into bars or squares. Serve warm or refrigerate for later.

Tips for Perfect High Protein Baked Oatmeal
- Use whey or plant protein powder carefully – Different types absorb liquid differently. If your batter feels too thick, add a splash of extra milk.

- Make it dairy-free – Use almond or coconut yogurt and plant-based milk.
- Meal prep hack – Bake on Sunday and cut into 6–8 slices for ready-to-go breakfasts all week.
Storage and Reheating
- Fridge – Store slices in an airtight container for up to 5 days.
- Freezer – Wrap individually and freeze for up to 2 months. Reheat in the microwave or oven.
- On-the-go – Pack a slice in a lunchbox for a portable, protein-rich snack.
