  • Cook Time: 35 minutes
  • Total Time: 1 hour 5 minutes
  • Yield: 9 large squares 1x




  • 2 1/2 cups steel cut oats (*Please see note below about using different types of oats.)
  • Water- Use the amount of water the package directions for your oats suggests.
  • 1 and 1/2 cups all-purpose flour
  • 1/2 cup almond flour (*Note: If you don’t have available it’s OK to use an extra 1/2 cup of all purpose instead.)
  • 1/8 cup granulated sugar
  • 1/8 cup brown sugar
  • 1 teaspoon cinnamon
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 8 tablespoons melted butter or coconut oil
  • 2 large eggs
  • 2 tablespoons vanilla extract
  • 1 cup assorted nuts, dried fruit, etc. (I used almonds, pecans, walnuts, and dried cherries.)


  • 1/4 cup powdered sugar
  • 2 tablespoons maple syrup
  • tiny splash of milk or water


1. Preheat the oven to 350*. Line a 8×8 baking pan or Pyrex (*Please see note below on pan sizes.) with a piece of parchment paper. Set aside.

2. Follow the package directions for cooking your steel cut oats. However, only cook the oats for 10 minutes, regardless of the package’s suggested cook time. Drain the oats, getting rid of as much water as possible. Set aside to cool.

3. In a large mixing bowl add flour, sugar, brown sugar, cinnamon baking soda, and salt. Stir so that all the ingredients are evenly distributed.

4. Add the cooked oats, butter or coconut oil, eggs, and vanilla, mix until the the ingredients are well combined. The dough will be moist, and very thick. Add the 1 cup of assorted add ins and mix gently until evenly distributed.

5. Dump the dough into the prepared pan and use your hands or a rubber spatula to flatten the dough into an even flat surface. Bake at 350* for 30-35 minutes. The bars will be set, but still soft when you  press gently on them, when they are done. Allow the bars to cool completely in the pan before cutting. If you are glazing the bars, you may do so right away, but still allow the bars to cool fully before cutting.


1. Add the powdered sugar, maple syrup, and splash of milk or water to a small sauce pan over low heat. Allow the ingredients to melt together mixing regularly to prevent burning. When fully melted and combined drizzle over the breakfast bars.


  • This recipe was written and tested with regular steel cut oats. Using quick cooking oats may change the final outcome of the recipe. However, many readers did have good success with the recipe using other types of oats. Please see the comments section for thoughts on how to modify this recipe to use other types of oats.
  • I made my bars using an 8×8 pan which does fill the pan completely to the top and yields a very thick bar. A 9×13 pan can be substituted for thinner bars. Also, depending on the brand of oats you use, etc. your oats may expand more than mine did and fit better in a larger pan as well. Just be sure to check your bars a little sooner if you use a larger pan as they may cook faster since the mixture is spread out more in a larger pan.
