Prep the pan. Heat oven to 350°F (175°C). Line an 8-inch square pan with parchment, leaving overhang on two sides for easy lifting.
Lightly grease the parchment.
Whisk dry ingredients. In a large bowl, mix oats, flour, baking soda, salt, and cinnamon.
Mix wet ingredients. In a separate bowl, whisk brown sugar, maple syrup, melted butter, oil, egg, vanilla, and almond extract until smooth.
Combine. Pour the wet mixture into the dry and stir until almost combined. Fold in cherries, chocolate, and nuts.
Press and level. Scrape batter into the pan. Use a spatula or damp fingertips to press it into an even layer.
Sprinkle a few extra chocolate chunks on top if you like.
Bake. Bake 18–22 minutes, until the edges are golden and the center is just set. A toothpick should come out with moist crumbs, not wet batter.
Cool completely. Let the pan cool on a rack for at least 45 minutes. Lift out using the parchment and slice into bars.
