Blackberry Oatmeal Bake

This sweet summery blackberry oatmeal bake is a perfect healthy breakfast. With ripe juicy blackberries in every bite, this is an easy dish your whole family will love.

Ripe juicy berries are one of the greatest delicacies of summer. This delicious blackberry baked oatmeal is one of my family’s favorite recipes for summer berries. Whole grain oats are sweetened with brown sugar, lightly spiced with cinnamon and vanilla, and baked with plump blackberries in every bite. Topped with a drizzle of honey or maple syrup, this oatmeal is the perfect way to start your day. You can make it ahead and reheat single servings all week to get you through your busy mornings! 

We love to serve this oatmeal bake topped with peanut butter or greek yogurt for a boost of protein, with a green smoothie or extra berries on the side. Served warm and topped with a scoop of ice cream, this can totally pass as dessert.

Ingredients

To make blackberry oatmeal bake, you need the following simple ingredients (exact measurements are in the recipe card below):

  • Old fashioned oats: For the best results, make sure to use old fashioned whole oats, not steel cut oats or quick oats. 
  • Cinnamon
  • Baking powder
  • Salt
  • Milk: I have made this with 2% milk and skim milk with success. I haven’t tried plant-based milks, but I think oat milk, almond milk and coconut milk would all taste good in this recipe – so give them a try!
  • Light brown sugar, packed
  • Eggs
  • Butter, melted
  • Vanilla extract
  • Fresh blackberries: Ripe fresh berries are best for this recipe. I have used blueberries in place of blackberries, which was great. I haven’t used frozen berries, but you could certainly try it so you can have this yummy baked oatmeal any time of year. If using frozen berries, I would recommend thawing them under warm water and patting dry with a paper towel before adding them to the oatmeal – that way, they will release less water while the oatmeal bakes.

Instructions

Step One: Preheat the oven to 350 degrees F. Grease a 9×13 casserole dish with olive oil or butter. 

Step Two: Add the oats, cinnamon, baking powder and salt to a large mixing bowl. Stir well to combine.

    1. Thanks so much for your comment Kristina. The recipe needs 2 eggs. So sorry for the oversight. I just updated the recipe card. I hope you love it!

    This is an amazing recipe! We loved it. Biggest suggestion would be consider making a second dish of it because it doesn’t last long at family gatherings.
