Let me show you how easy it is to make these healthy, delicious baked blueberry oatmeal bars!
Step 1: Make sure you have all the ingredients
For these healthy baked oatmeal bars, you’ll need just a few simple ingredients – likely things you already have in your fridge or pantry. Here’s a quick checklist:
- Eggs
- Milk (your preference – dairy or plant-based)
- vanilla extract
- salt
- honey
- fresh or frozen blueberries
- old fashioned rolled oats
- sliced almonds
For exact ingredient amounts and full recipe directions, be sure to reference the recipe by scrolling down to the bottom of the post.
Step 2: Mix wet ingredients
Using a mixing bowl and whisk, combine the eggs, milk, vanilla, salt and honey. Whisk together until the honey becomes well incorporated with the rest of the ingredients.
Step 3: Add the oatmeal, almonds and fold in blueberries
To your liquid ingredients, you can then add the oatmeal and almonds. Reserve a couple of tablespoons of the almonds for topping. Mix together using rubber scraper.
Next, gently fold in the blueberries. If you are using frozen blueberries, they don’t have to be thawed. Simply add in while still frozen.
The mixture will be thick and look almost like granola.
Step 4: Pour oatmeal into pan and top with reserved almonds
Pour into a prepared 9×9 pan or medium baking dish sprayed with a good quality non-stick baking spray. I like to use Spectrum Coconut Oil Spray. Top with the reserved sliced almonds.
You can do one of two things next:
- Bake right away, or
- Place in baking dish and refrigerate for baking later. If you want to serve this first thing in the morning, mixing the oatmeal in advance is a great way to save some time.
Step 5: Bake
Bake the prepared oatmeal for 32-35 minutes or until golden brown. Remove from oven and let cool 10 minutes before slicing.
You’ll have the most delicious, healthy baked oatmeal bars you’ve ever tasted. These are fantastic eating right away while warm. You can also refrigerate or freeze for later when you need a quick breakfast on a weekday morning before work or school.

FAQ’s about this blueberry baked oats recipe:
Add more protein to this recipe by adding vanilla protein powder or collagen protein. A 1/2 cup of protein powder or collagen would be ideal. Mix this in when you add the oatmeal to the wet ingredients. Other good protein options would be serving these oatmeal bars with Greek yogurt or cottage cheese.
You can certainly make this baked oatmeal into muffins. Line a muffin tin with paper cupcake liners or use silicone baking cups. Equally divide the batter into all 12 cups, and bake for 28-30 minutes or until golden brown.
Baked oatmeal can certainly be made in advance of serving. Bake as directed, then let cool completely to room temperature. Cover with plastic wrap and refrigerate until ready to serve. Heat individual slices in the microwave or heat the entire pan in the oven at 325 for 15-20 minutes.
Baked oatmeal can definitely be frozen. I recommend slicing into individual servings. Place the slices in a freezer-safe container or freezer bag. Frozen oatmeal bars will keep in the freezer for up to three months. Thaw in the refrigerator or at room temperature overnight. Reheat in the microwave.
What can I serve with these healthy baked oatmeal bars?
This baked blueberry oatmeal goes great with Greek yogurt and additional blueberries and almonds. I prefer plain full-fat Greek yogurt. These oatmeal bars would also be great with scrambled or hard-boiled eggs or cottage cheese for additional protein.
How do I meal prep baked oatmeal?
- Once the baked blueberry oatmeal comes out of the oven, let cool completely. Slice into 8 equal bars. (Photo above) I placed an oatmeal bar into my meal prep container and added some Greek yogurt and additional berries and almonds. Refrigerate for up to 5 days. Reheat the oatmeal bars in the microwave for 30-60 seconds, or enjoy cold. This is a fantastic filling, protein-packed breakfast that will keep you full for hours!

If you add protein powder or plain collagen to you need to add any additional liquid?
Very tasty. Unfortunately I used an 8 X 8 pan and the bars took much longer to bake. Super filling. Would be great with a cup of coffee! Thanks for the recipe.
Can you use quick oats or must be old fashioned?
In a pinch you can use instant or quick oats, however, the consistency will not be as desirable. Old fashioned rolled oats tend to hold their shape better and will reheat better as well. Let me know if you tried the quick oats and if they turned out okay. Thanks!
Wow! My new favorite baked oatmeal! I didn’t have a nine inch square pan so I used a nine inch cake pan. Cut into six wedges (327 calories per serving). This is a keeper! Frozen blueberries lent a lot of moisture without making it soggy. Don’t forget the almonds. They give it a nice crunch.
