Preheat the oven to 350°F. Spray Chosen Foods Avocado Oil Spray on a standard sized donut pan and set aside
First, make the crumb topping. In a small bowl combine the melted butter, brown sugar, granulated sugar, flour, cinnamon and salt. Use a fork to stir together until the mixture clumps together. Set aside.
In a medium bowl, whisk together the flour, sugar, baking soda, baking powder, and salt.
In a separate bowl, whisk together the egg, sour cream, Chosen Foods Avocado Oil, milk, and vanilla extract. Pour the wet ingredients into the dry, mixing until just combined. The mixture will be slightly lumpy and thick.
Transfer the batter into a large piping bag (you can also use a plastic bag if you don’t have one!) and cut off the tip of the piping bag to leave a ½ inch opening.
Pipe the dough into the prepared donut molds, filling 1/2 of the way to the top of the molds. Top with the crumb topping, pressing it gently into the tops of the donuts so it sticks. Bake until golden brown and the donuts sprig back to the touch, about 13 minutes. Allow to cool in the pan for 5 minutes before inverting the donuts out of the pan and transferring to a cooling rack to cool slightly.
While the donuts cool, make the vanilla glaze. In a small bowl whisk together the confectioners sugar, milk, vanilla and salt until smooth. Drizzle over the cooled donut and enjoy!
