Healthy Berry Oatmeal Bars Breakfast

These berry oatmeal bars deliver the perfect mix of wholesome and craveable qualities for breakfast or an anytime treat. The buttery oat crust acts as both a crunchy base and a cozy crumble topping, with a sweet tangy berry filling tucked in between. You will not believe how easy they come together using frozen berries and just one mixing bowl for the base and crumble. I have relied on these bars as a school snack for my kids and a weekend pick me up for myself.

I first cooked up these bars during a busy back to school week when I was looking for a healthy grab and go breakfast. My family raved and now I make double batches to keep up with demand.

Step-by-Step Instructions

Prepare the Pan:

Line a nine inch square pan with parchment paper to prevent sticking and make the bars easy to remove later.

Make the Berry Filling:

Put the frozen berries in a saucepan with lemon juice coconut sugar maple syrup and a pinch of sea salt. Warm gently for about eight minutes until the berries burst and the mixture becomes juicy. In a cup whisk the tapioca starch with a tablespoon of berry liquid until smooth then stir that back into pan. Simmer for one minute to thicken remove from heat and set aside.

Mix the Oatmeal Crust and Topping:

In a large bowl combine the rolled oats almond flour baking soda and sea salt. Add the maple syrup coconut oil and vanilla and use a fork to mix. Rub with your fingers as needed until the mixture is evenly combined and crumbly.

Layer the Bars:

Scoop out about half a cup of the oat mixture and save it for the topping. Press the remaining oat mixture firmly into the bottom of the pan using your hands or the back of a measuring cup to make an even base.

Spread Berry Filling:

Pour the berry mixture over the oat base and smooth with a spatula making sure it covers evenly right to the edges.

Finish with Crumble:

Sprinkle reserved oat mixture over the top in small and large pieces for a rustic look.

Bake and Cool:

Slide pan into the oven and bake at three hundred seventy five degrees Fahrenheit for about twenty to twenty five minutes until the edges are golden and the top looks set. Let bars cool fully in the pan before slicing to help them stay firm.

Save

I especially love the combination of tangy frozen raspberries and blueberries in the filling. My son always asks for the corner slice that has the thickest berry layer and it makes me smile every time I pack one in his lunchbox.

Storage Tips

These bars keep best in the fridge for up to five days in an airtight container. Stack them between layers of parchment to prevent sticking. For longer storage freeze bars in a single layer then transfer to a zip top bag and thaw overnight as needed. They are excellent enjoyed cold straight from the fridge.

Ingredient Substitutions

You can swap maple syrup for honey if not vegan just note the flavor will be slightly different and sweeter. Coconut sugar can be substituted with light brown sugar. Use melted butter instead of coconut oil if dairy is not a concern. For nut free try oat flour in place of almond flour. The berry mix is flexible so change up with whatever frozen berries you enjoy most.

Serving Suggestions

Serve bars warm for dessert with a scoop of Greek yogurt or plant based yogurt for breakfast. They also fare well as a tucked away midday pick me up with coffee or tea. Pack them for hiking or picnics as a sturdy hand held treat.
