These blueberry donuts are soft and fluffy cake donuts filled with blueberries topped with a sweet and tart lemon glaze. Make these blueberry cake donuts for a fun breakfast!
In another large bowl, pour the light brown sugar, granulated sugar, egg, sour cream, milk and vanilla extract. Whisk well to fully combine. Next, whisk in the melted butter until.
Spoon or pipe the blueberry donut batter into each of the prepared donut cavities in the donut pan. This should fill about ¾ of each cavity of the donut pan. Bake 10 - 12 minutes.
Cool the donuts in the pan for 5 minutes before gently taking them out to cool on a cooling rack. Make the lemon glaze by whisking the powdered sugar with lemon juice.
Dip the top of the cooled blueberry donut into the lemon glaze, shake off any excess and return to the cooling rack to fully set. Once set, enjoy your delicious, bakery worthy blueberry donuts!
