I’ve been feeling blue lately, but in a happy way.

For the last few weeks I’ve been getting a wonderful harvest from my blueberry bushes. The first few days of picking, I had a garden friend who was not a bluebird of happiness.

It was a bluejay who was anything but happy with me. This little guy would perch on the fence near the blueberries and squawk loudly at me. Then move to the nearby pear tree, followed by the raspberry trellis, and the apple tree, rotating around me squawking from every angle.

He definitely wanted to let me know that I had no business picking his berries!

Blueberries ready to pick

In the end, I think we came to an understanding. There were enough berries for me to pick and put up for the season, with a few extra for my bluejay buddy and his bird friends to enjoy.

I love using these berries in so many ways, and fortunately I have enough to enjoy some fresh and also freeze plenty to get me through the year.

They find their way into muffins, pancakes, smoothies, oatmeal, berry sauce, and now these blueberry oatmeal bars.

Ingredients in these blueberry bars

For the oatmeal bars:

  • Oatmeal – I used regular oats, but quick oats can be used
  • Whole wheat flour – for gluten free bars, use a gluten free flour blend
  • Baking powder
  • Salt
  • Maple syrup
  • Applesauce
  • Vanilla

For the filling:

  • Blueberries – fresh or frozen
  • Maple syrup
  • Lemon juice
  • Cornstarch
  • Vanilla
  • Water

For the optional lemon glaze:

  • Powdered sugar – this does add a small amount of processed sugar to the recipe
  • Lemon juice – the lemon flavor perfectly complements the blueberries

How to Make These Blueberry Oat Bars

Step 1:

Combine the blueberries, lemon juice, and maple syrup in a medium sized saucepan. Bring the berries to a boil, stirring occasionally. Reduce the heat to simmer, and stir in the vanilla extract and the cornstarch/water mixture. Stir briefly until the filling thickens. Then set aside.

Step 2:

In a large mixing bowl, combine the oatmeal, flour, baking powder, and salt.

Step 3:

In a separate small bowl, stir together the applesauce, maple syrup, and vanilla. Stir the applesauce mixture into the oatmeal mixture, and combine well.

Step 4:

Spread half of the oatmeal mixture evenly onto the bottom of a parchment lined 9″ x 13″ baking pan. Pour the berry filling on top of this oatmeal layer and spread evenly. Take the remaining oatmeal mixture and crumble it on top of the berry layer.

Step 5:

Bake the berry bars at 350° F for 30 minutes.

After baking, let them cool to firm up.

If using the optional lemon glaze, wait until the bars are completely cool before drizzling the glaze over the bars.

Since these bars are sweetened with maple syrup, they are refined sugar free. My husband and I enjoy the lightly sweetened taste of these bars, but if you want them to be a little sweeter, the glaze is perfect and only adds a small amount of sugar per bar. The glaze is flavored with lemon juice, which is a perfect complement to the blueberries.

These make perfect breakfast bars, can easily be packed in a lunch, or enjoyed for an afternoon snack.

For a special treat, these blueberry oat bars would be amazing topped with my vanilla ice cream! And if you have a nice harvest of strawberries (or even some frozen strawberries) be sure to try out my strawberry ice cream!
