Turn your oven on and set it to 350°F (175°C). Coat your donut pan with cooking spray or rub it with butter. This way, the donuts pop out easily when they're done.

In a bowl, mix together the flour, sugar, salt, baking powder, and baking soda. Stir until everything's combined nicely so your donuts will turn out evenly fluffy.

In another bowl, beat the egg until it's bubbly. Then, add in the buttermilk, vanilla, and cooled melted butter. Mix it all together until smooth, but don’t overdo it!

Pour the wet mixture into the bowl with the dry stuff. Use a spatula to gently fold everything together. It's okay if a few lumps remain! Toss in the raspberries last, stirring just enough to mix them in without crushing them too much.

Carefully spoon your batter into the donut pan wells, filling them about three-quarters of the way. For precision (and to keep things clean), you can use a ziptop bag with the corner cut off to pipe the batter in.

Put the pan in the oven and let the donuts bake for 12-15 minutes. They're ready when they spring back when gently poked, and a toothpick comes out mostly crumb-free.

While the donuts are cooling, mash the raspberries with lemon juice in a small bowl. Strain this through a sieve to remove any seeds, then stir the smooth puree into the powdered sugar. If it seems too thick, add a few tiny splashes of milk until it’s just right.

Once the donuts are cool to the touch, dunk the tops into the glaze. Twist them slightly as you pull them out to catch any drips. Transfer to a rack, and while the glaze is still wet, you can sprinkle on some extras or top with bits of fresh raspberry.
