Instructions:

Preheat your oven to 350°F (or 425°F for a different texture) and prepare a standard donut pan by spraying it with nonstick spray.

In a large mixing bowl, combine the flour, sugar, baking powder, and baking soda. Whisk together until well blended.

In another bowl, whisk together the egg, buttermilk, melted butter, and vanilla extract until smooth.

Pour the wet ingredients into the bowl with the dry ingredients and gently mix until just combined. Be careful not to overmix.

Fold in the chopped cherries or cherry jam to the batter, ensuring they're evenly distributed.

Using a piping bag or a spoon, fill each cavity of the donut pan about 3/4 full with the batter.

Bake the donuts in the preheated oven for 10-18 minutes, or until a toothpick inserted into the center comes out clean.

Let the donuts cool in the pan for a few minutes before transferring them to a wire rack to cool completely.

Once cooled, apply your desired toppings, such as cherry glaze, cinnamon sugar, or any other toppings you prefer.

For the best results, remember to measure your ingredients accurately, as baking is a precise science.

Also, feel free to experiment with different flavorings or add-ins, such as chocolate chips or nuts, to personalize your cherry donuts. Enjoy the process and savor the delicious results!
