Protein-Rich Baked Oatmeal
Protein-rich baked oatmeal is a warm, sliceable breakfast bake made from rolled oats, mashed banana, almond milk, and vegan protein powder, baked until set into soft, cake-like squares. It gives you the comfort of oatmeal without the mushy, porridge-y texture, and one batch covers several mornings of meal prep. If you want a breakfast that holds together, travels well, and packs a real plant-based protein dose, this is the one to make.
If you’re not into the soft texture of a bowl of oatmeal but you’re all about a high plant-based protein dose, this is oatmeal done differently. I’ll teach you how to make a super easy version that works as breakfast, as a brunch centerpiece, and even as dessert with a scoop of ice cream on top. It’s versatile and quick, and you can assemble it ahead of time and bake it fresh for when, let’s say, guests arrive.
What goes into this baked oatmeal
Today I combine oats with bananas, almond milk, blueberries, maple syrup, vegan protein powder, and hemp seeds. Here’s why each one earns its place:
- Rolled oats are the backbone. They soak up liquid and firm up as they bake, which is what gives you clean, sliceable squares instead of a loose porridge.
- Ripe bananas do double duty: mashed banana binds the bake and adds natural sweetness, so you need less added sugar. The riper and more spotty they are, the sweeter the result.
- Almond milk is the liquid that hydrates the oats. Any unsweetened plant milk works here, so use what you have.
- Vegan protein powder is what makes this a high-protein breakfast rather than a standard oat bake. As I mentioned, it is a rich source of protein.
- Hemp seeds and sliced almonds add protein, healthy fats, and a bit of texture. See more hemp recipes if you want to use up the bag.
- Blueberries, maple syrup, cinnamon, and vanilla round out the flavor, while ground flaxseed mixed with water acts as a binder that helps everything hold together.
How to get the texture just right
The two moves that make or break this bake are hydrating the oats and setting up the flax binder. Covering the oats with boiling water and letting them sit for 15 to 20 minutes softens them before they ever hit the oven, so you avoid a dry, chalky center. In parallel, stirring the flaxseed with water and letting it rest for about five minutes lets it turn gel-like, which is exactly what holds the squares together once they cool.
A few more tips for a clean result: mash the banana until it’s fully smooth so you don’t get gummy streaks, and reserve those banana slices for the top instead of stirring them in, since they caramelize slightly and make the bake look inviting. Bake at 170 degrees Celsius for about 30 minutes. It’s ready when the top is set and springs back lightly to the touch. Then let it rest a few minutes before slicing, because it firms up considerably as it cools.
Easy swaps and variations
- Berries: swap the blueberries for raspberries, chopped strawberries, or diced apple. Frozen berries work too; no need to thaw them first.
- Protein powder: use whatever vegan protein you like. If you’re not sure which to buy, my roundup of the best vegan protein powders and this guide to protein in the vegan diet will help you choose.
- Nuts and seeds: sliced almonds can become chopped walnuts, pecans, or pumpkin seeds. Keep the hemp seeds in for their protein, or lean into them with even more hemp-based ideas.
- Sweetness: with very ripe bananas you can cut the maple syrup back a little. Taste your batter and adjust.
How to serve it
Warm from the oven, a square is lovely on its own or with an extra splash of almond milk poured over. For brunch, serve it with fresh fruit and a dollop of coconut yogurt. And when you want it as dessert, warm a square and add a scoop of vegan ice cream, the same trick that works so well with these vegan sugar-free desserts. If you’re building a high-protein morning, it pairs naturally with a high-protein smoothie on the side.
Make-ahead and storage
This is a meal-prep dream. Bake it on the weekend, cool completely, then cut into portions and keep them in an airtight container in the fridge for up to 4 to 5 days. Reheat a square in the microwave for 30 to 60 seconds, or warm it in the oven if you want the edges crisp again. It also freezes well: wrap individual squares and freeze for up to 3 months, then thaw overnight in the fridge or reheat straight from frozen. You can also assemble the whole thing the night before, cover it, refrigerate, and bake it fresh in the morning, which is exactly what makes it so handy when guests are coming.

Frequently Asked Questions
Yes. Every ingredient is plant-based: rolled oats, almond milk, ripe banana, blueberries, maple syrup, vegan protein powder, hemp seeds, sliced almonds, cinnamon, vanilla, and ground flaxseed. There are no eggs, dairy, or honey, so it’s fully vegan as written.
The exact amount depends on the vegan protein powder you use, since brands vary. Between the scoop of protein powder, the rolled oats, the hemp seeds, and the sliced almonds, it delivers a solid plant-based protein dose per serving, which is what sets it apart from a standard oat bake.
Absolutely, it’s built for meal prep. You can assemble the whole dish the night before, cover it, refrigerate, and bake it fresh in the morning. Or bake the full batch, cool it, and portion it out for grab-and-go breakfasts through the week.
Keep cooled, cut squares in an airtight container in the fridge for 4 to 5 days. Reheat in the microwave for 30 to 60 seconds or in the oven for crisper edges. It also freezes well for up to 3 months; wrap individual squares and thaw overnight or reheat from frozen.
Yes. Any unsweetened plant milk works in place of almond milk, so use what you have on hand. For the protein, use whatever vegan protein powder you like; a neutral or vanilla flavor blends most seamlessly with the banana and cinnamon.
Covering the oats with boiling water for 15 to 20 minutes softens them before baking so the center doesn’t turn out dry or chalky. Letting the ground flaxseed sit with water for about 5 minutes lets it turn gel-like, which acts as a binder and helps the squares hold their shape once cooled.
Perfect breakfast!
