Preheat your oven to 375°F (190°C) and line baking sheets with parchment paper.
In a large bowl, whisk together the flour, granulated sugar, dark brown sugar, cardamom, baking soda, and salt. Give it a good whisk to make sure everything is evenly distributed.
Pour the beaten egg, vanilla extract, melted butter, and milk into the bowl with the dry ingredients. Stir everything together with a wooden spoon or spatula until just combined. Don't overmix!
Now for the stars! Add the rolled oats, dark chocolate chips, and diced fresh cherries to the dough. Gently fold them in until they are just incorporated throughout the dough. You want to see those pockets of chocolate and cherry!
Drop rounded tablespoons of dough onto your prepared baking sheets. Leave about 2 inches between cookies as they will spread slightly. I like to use a cookie scoop to get uniform sizes, which helps them bake evenly.
Bake for 9-11 minutes, or until the edges are lightly golden and the centers still look a little soft. They will continue to set up as they cool.
Let the cookies cool on the baking sheets for a few minutes before carefully transferring them to a wire rack to cool completely.
