Ingredient Notes

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

Ingredients needed to make this recipe in glass bowls and measuring cups.
  • 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.

Steps to make this recipe in a white ceramic bowl.
  • 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.

Prep: 10 minutes

Total: 50 minutes

Equipment

  • 8×8 or 9×9 inch square baking dish
  • mixing bowls

Ingredients 

  • 2 cups old fashioned oats
  • 1 tsp cinnamon
  • ½ tsp salt
  • ¼ cup brown sugar
  • ¼ cup sliced almonds
  • ¼ cup chopped pecans , or walnuts
  • ¼ cup protein powder, I use vanilla flavored
  • 3 Tbsp maple syrup
  • 2 eggs
  • 1 tsp vanilla or almond extract
  • 2 cups fresh blackberries

Instructions 

  • Preheat the oven to 350 ºF spray an 8×8 or 9×9 inch square baking dish with olive oil or avocado oil. Try to keep the baking dish as close as possible in size for the best outcome. 
  • 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.
  • When ready to serve, gently scoop out into a bowl or plate. It will be a tad crumbly but I prefer it this way, it feels more like a decadent treat. Serve with extra blackberries if desired.
