Moist and golden donut rings with a tropical twist, featuring sweet potato and caramelized pineapple.
Preheat your oven to 350°F (175°C) and lightly grease a standard donut pan.
In a large mixing bowl, whisk together the mashed sweet potatoes, drained crushed pineapple, brown sugar, and granulated sugar until smooth and well combined.
Add in the vegetable oil, eggs, and vanilla extract. Whisk until everything is evenly incorporated and the mixture is creamy.
In a separate bowl, combine the all-purpose flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
Gradually add the dry ingredients to the wet mixture, folding gently with a spatula. Be careful not to overmix—just until there are no visible streaks of flour.
Spoon or pipe the batter into the prepared donut pan, filling each ring about 3/4 full.
Bake for 15 to 18 minutes, or until the donuts spring back when lightly pressed and a toothpick inserted comes out clean.
Allow the donuts to cool in the pan for 5 minutes, then gently loosen and invert onto a cooling rack so the caramelized pineapple side is on top.
Serve warm as is, or dust with a bit of extra cinnamon or powdered sugar for a pretty finish.
