To prepare, preheat the oven to 350F and position the oven rack in the center. Spray ONE Non-Stick 6-Cavity Donut Baking Pan with nonstick spray and then set it aside.

Sift the dry ingredients (including sugar) together in a mixing bowl.

In a separate bowl combine the peanut butter, vinegar, vanilla extract, and hot water. Whisk together until the peanut butter is fully dissolved in hot water.

Add the wet ingredients to the dry ingredients. Quickly whisk together until the vegan chocolate donut batter is fully combined and smooth.

Transfer the donut batter to a piping bag or a ziplock bag. Fill each well with the donut batter. You can totally fill them all the way to the top. Just make sure not to cover the center of each donut.

Place the donut pan in the oven and bake for 9-11 minutes or until a cake tester/toothpick inserted in the center comes out clean.

Remove the doughnut pan from the oven and allow it to cool for about 1-2 minutes on a cooling rack.

Remove the gluten free vegan donuts from the pan. Place them on a wire rack to cool completely before glazing.

Combine the dark chocolate chips, unsalted non-dairy butter, kosher salt, and corn syrup in a heat-proof bowl.

Place it on top of a small saucepan with hot (not boiling) water. Allow the heat of the water to melt the ingredients together.

If you like, add some instant espresso powder to bring out the chocolate flavor. Make sure the instant espresso is like a powder or the glaze will have a grainy texture.

Once fully melted, use a small whisk and whisk all the ingredients together until a smooth and shiny glaze has formed.

Once the gluten free vegan chocolate donuts are completely cool, place the wire rack with the donuts on top of a sheet tray lined with a piece of parchment paper.

Take each donut and gently dip it into the bowl of glaze, making sure to cover the top of the donut completely. Lift the donut out of the glaze and allow any excess glaze to drip off.

Sprinkle the donuts with Sprinkles or other garnishes if you like.

Allow the glaze to set for 10 minutes before serving.
