Start your morning with a soft, chewy Blueberry Oatmeal Breakfast Blondies. It has the texture of a blondie but uses oats and blueberries to make it feel more like a breakfast option. Itโs quick to mix, holds up well when stored, and works great for busy mornings. It also works well for kidsโ lunches or as a snack on the go.

Blueberry Oatmeal Breakfast Blondies
I like this recipe because it makes breakfast feel like a treat without being too sweet. These blondies come together fast and can be made in one bowl.
You can use frozen blueberries if you donโt have fresh ones. Just stir them in frozen so they donโt bleed into the batter. You can also swap in strawberries, blackberries, or even diced apples.
Maple syrup or honey can work in place of brown sugar, depending on what you have on hand. People like this recipe because itโs simple, portable, and holds up well for a few days.
I make these blondies for on-the-go breakfasts. After I cook them and they cool, I package them individually and refrigerate. In the mornings, I grab one and go. Sometimes, I microwave it a few seconds but they’re cold too.
I have not tested mixing everything the night before and baking it in the morning.

What is a blondie?
We all know what brownies are, but what are blondies? Blondies are brownies without the cocoa. Thus, they’re ‘blond’. They’re sweet, moist, and dense cakes that are sturdy enough to eat with your hands, not with a fork.

These breakfast blondies aren’t as sweet as normal blondies. They are lightly sweetened with brown sugar. You can substitute monk fruit blend, maple syrup, honey, or coconut sugar.
I also added in-season blueberries. Feel free to add any fresh or dried fruit.
I also added very ripe mashed bananas. They make the bars soft, moist, and sweet. You can substitute applesauce.
The oatmeal adds texture and makes these breakfast blondies chewy. Be sure to use old-fashioned rolled oats, not instant.
For protein, I added peanut
I have not tested these with gluten-free flour.

Tips for Making
- This makes a great recipe for kids to help you in the kitchen.
- Add 1/2 cup of your favorite nuts, pecans, walnuts, and almonds to the batter.
- Perfect bananas for baking donโt look so perfect. Allow the bananas to get very ripe, very speckled, or even almost black. The darker the skin of a banana, the sweeter the fruit will be. The sweeter the fruit, the better your dessert or blondies will be!
- Also, try adding dried raisins, blueberries, or cranberries to your mixture.
