Preheat oven to 350°F (175°C) and grease your doughnut pan. No one likes a doughnut that won’t come out.
In a bowl, whisk together flour, sugar, baking powder, baking soda, cinnamon, and salt. Yes, dry drama first.
In a separate bowl, combine coffee, milk, oil, vanilla, and vinegar. Give it a good stir like your ex’s texts—brief.
Add wet to dry and mix until just combined. If it’s too smooth, you’re doing too much.
Spoon batter into pan, filling each cavity about ¾ full—don’t get greedy.
Bake for 13–14 minutes or until a toothpick comes out clean and you smell something fabulous.
Cool in the pan for 5 minutes, then move to a wire rack like the classy woman you are.
Optional but highly recommended: brush tops with warm coffee syrup or dust with cinnamon sugar.
Pair with your favorite mug and a moment of peace—if that still exists.
Store leftovers in an airtight container (if there are any, you beast).
