Homemade Blueberry Oatmeal Breakfast Bars Recipe

These Blueberry Oatmeal Breakfast Bars are a quick, grab-and-go breakfast or snack that’s healthy, kid-friendly, and simple to make.

Blueberries and breakfast have always gone together for me — whether folded into pancakes, stirred into oatmeal, or bursting through a warm muffin. They’re one of those fruits that make morning meals feel special without a lot of fuss. These Blueberry Oatmeal Breakfast Bars capture that same comforting flavor in a portable, reheatable form. They’re chewy, moist, and studded with juicy blueberries in every bite.

Life can get hectic, and when you’re short on time it’s easy to skip breakfast. Preparing a pan of these bars on the weekend means you’ll have a wholesome option ready all week. I like to make them on Sunday alongside my meal prep so we can grab a bar and go — they reheat well and travel easily in a lunchbox or bag. They’re also an approachable recipe for kids and make a great after-school snack or a simple dessert when served with a scoop of ice cream.

How to Make Blueberry Oatmeal Bars

This recipe is straightforward and uses pantry-friendly ingredients. Start by combining the dry ingredients in one bowl and the wet ingredients in another. Stir the wet into the dry until just combined, fold in the blueberries, then spread the batter into an 8×8-inch pan and bake. The result is a soft, slightly chewy bar with pockets of melted blueberry throughout.

A key ingredient is oat flour, which lends a light, tender texture to baked goods. You can buy oat flour or make your own by blending rolled oats or quick oats in a food processor or blender for about a minute, until they form a fine, powdery flour. One cup of oats yields about one cup of oat flour, so it’s easy to measure, and homemade oat flour keeps for a couple of months stored in a cool, dry place.

These bars bake in about 35–40 minutes and then need a short rest before you remove them from the pan and cool completely. Cut into 9 large squares or 16 smaller bars depending on how big you like them.

Prepping and Storage

This recipe yields about 9 large bars or 16 smaller bars. Cutting them smaller makes it easier to enjoy more than one without feeling too indulgent. Store the bars covered in the refrigerator for up to one week, or wrap them individually and freeze for up to two months. They thaw quickly at room temperature or can be reheated in the microwave for a warm breakfast.
