Preheat oven to 350°F (175°C), grease that doughnut pan like your life depends on it.
In a bowl, whisk together flour, sugar, baking powder, soda, cinnamon, and salt—pretend you're hosting a cooking show.
In another bowl, mix coffee, almond milk, oil, vanilla, and vinegar—aka the wet team.
Combine the wet and dry ingredients just until you stop judging yourself.
Fold in the chopped hazelnuts. No overmixing. We’re not making bricks.
Spoon batter into the doughnut pan about ¾ full.
Bake for 12 minutes or until golden and a toothpick comes out clean (not doughy lies).
While they cool, mix topping ingredients in a saucepan until glossy and fabulous.
Once doughnuts cool slightly, drizzle with the hazelnut-maple topping.
Devour like no one’s watching—because they aren’t. They’re too busy asking for the recipe.
