Preheat the oven to 350?F (175?C) and grease a baking dish.

In a mixing bowl, combine rolled oats, flour, brown sugar, melted butter, honey, baking soda, and salt.

Mix until well combined and crumbly.

Press half of the mixture into the bottom of the greased baking dish.

In a separate bowl, mix the chopped cherries with lemon juice and sugar (if using).

Spread the cherry mixture evenly over the pressed oat base.

Crumble the remaining oat mixture over the cherry filling.

Bake in the preheated oven for 25-30 minutes or until golden brown.

Allow to cool before cutting into bars.
