Ingredient Notes
All other ingredients and measurements can be found in the recipe card towards the bottom of this post.

- Old Fashioned Oats. These are also called rolled oats. Use gluten free if needed.
- Cinnamon & Salt.
- Protein Powder. This adds flavor and protein! I use vanilla protein powder. It is optional to use this ingredient.
- Brown Sugar. For a deeper flavor and some sweetness.
- Nuts. I use sliced almond and chopped pecans. Walnuts will also work.
- Eggs. This keeps everything combined when baking.
- Maple Syrup. To add a yummy maple flavor.
- Vanilla Extract.
- Milk. I use almond milk but any nut milk or cows milk will work.
- Blackberries. Fresh blackberries work best but frozen will also work as well it will just be a little more runny.
Steps To Make Blackberry Baked Oatmeal
Ready to bake blackberry baked oats? Let me walk you through the recipe. For your convenience, there is a full ingredient list and detailed instructions in the printable recipe card below.

- Step One. Preheat the oven to 350º. In a large bowl mix the dry ingredients together, including the protein powder: oatmeal, protein, nuts, spices, salt, brown sugar.
- Step Two. In another medium bowl, whisk the wet ingredients together: eggs, milk, maple syrup, vanilla extract.
- Step Three. Mix the wet and dry ingredients together and then fold in the blackberries.
- Step Four. Add the mix to a greased or parchment lined baking dish and bake for 40-45 minutes or until the edges are browned and the center is no longer jiggle. Be SURE to let it cool for about 10 minutes. This helps to ensure the oatmeal stays together better. This oat bake does crumble a bit when serving, which I prefer as it’s much more decadent that way.

Blackberry Baked Oatmeal Tips
- To make it healthier, cut back on the brown sugar. I love the added sweetness but you can easily make it with less sugar. Calorie free sweetener is also an option.
- This oatmeal bake is a bit crumble when served (but trust me it’s so so good). I enjoy it best this way, it makes it more interesting with texture and less dense when enjoying. The blackberries also cause this.
- Frozen blackberries work, but they will be a bit more runny/watery.
- If you want to make this for dessert, add a scoop of ice cream for an extra yummy treat.

Instructions

- In a large bowl, whisk or stir the old fashioned oats, cinnamon, chopped walnuts, sliced almonds, brown sugar, vanilla protein powder of choice and salt until combined.
- In a separate bowl, whisk together the eggs, almond milk, vanilla extract, maple syrup.
- Pour the wet ingredients into the oat mixture and stir to combine. Gently fold in the blackberries. Pour the mixture into the baking dish and spread it evenly using a spatula.
- Bake for 40-45 minutes or until golden brown on the edges and middle is no longer jiggling.
- Remove from the oven and let it cool for 10 minutes, this helps the baked oatmeal stick together more.
