2 cups oats
1/2 cup sugar
1/2 teaspoon salt
1/4 teaspoon cinnamon or other spices as desired (cardamom, nutmeg, etc.)
2-1/2 cups additions:  Dried fruit, seeds, nuts, flax meal, bran cereal, puffed rice cereal, crushed pretzels, chocolate chips…whatever you like. (I used chocolate chips, raisins, and black walnuts)
1/3 cup creamy peanut butter
6 tablespoons olive oil, canola oil, other oils….or melted butter (I used butter)
1/4 cup honey, maple syrup or Agave syrup
1 tablespoon water

Preheat oven to 350 degrees Fahrenheit. Depending on desired thickness, line a square (8×8 or 9×9) or rectangular (9×13) baking dish with parchment paper (aluminum foil works too), then lightly grease the paper with a non-stick cooking spray, oil, or butter. Thicker bars are a little more decadent, if you’re planning on using this as a dessert.

Process 1/3 cup of the oats in a blender or food processor until finely ground.

If necessary, chop up dried fruit and nuts.

Stir together all dry ingredients (oats, ground oats, sugar, salt, cinnamon, fruits/seeds/nuts).

Whisk together wet ingredients (oil/butter, honey, peanut butter, and water).

Mix together wet and dry ingredients and then spread in the pan. Press firmly into the corners and edges so the top is even.

Bake for around 30 minutes or until the top starts to brown. Thicker bars will likely take longer, so you’ll need to watch them, depending on how much batter you’ve spread in what size pan. The edges will become deep golden, and they may feel underdone in the center, but that’s okay. They’ll firm quite nicely as they cool.

Let cool in the pan on a cooling rack for at least 20 minutes, then take them out of the pan using the parchment paper/foil. Let cool completely before cutting.
