1/2cupbuttermilk (or substitute with 1/2 cup milk mixed with 1/2 teaspoon vinegar)
1/4cupunsweetened applesauce
1largeegg
1teaspoonvanilla extract
1/4cupcreamy speculoos spread (to be used as a filling)
to tastenonePowdered sugar (for dusting)
Instructions
Preheat your oven to 350°F (175°C). Lightly grease a doughnut pan with cooking spray to prevent sticking.
In a large mixing bowl, combine the all-purpose flour, packed brown sugar, baking powder, baking soda, ground cinnamon, ground nutmeg, and salt. Whisk together until all dry ingredients are evenly distributed and there are no lumps.
In a separate bowl, whisk together the buttermilk, unsweetened applesauce, egg, and vanilla extract until the mixture is smooth and well blended.
Carefully pour the wet mixture into the bowl with the dry ingredients. Gently stir until just combined, being cautious not to overmix; a few lumps are perfectly fine.
Transfer the batter into a piping bag or a resealable plastic bag with the corner snipped off. This will make it easier to fill the doughnut cavities.
Fill each doughnut cavity about halfway with the batter, then add a small dollop of speculoos spread in the center of each. After adding the speculoos, top with more batter until the cavities are about three-quarters full.
Place the pan in the preheated oven and bake for 12-15 minutes. The doughnuts are done when a toothpick inserted into one comes out clean, with no batter sticking to it.
Once baked, remove the pan from the oven and allow the doughnuts to cool in the pan for about 5 minutes. Then, gently transfer them to a wire rack to cool completely.
When the doughnuts are completely cool, dust them generously with powdered sugar before serving. Enjoy your deliciously spiced treats!
Notes
Arrange the doughnuts on a decorative plate and sprinkle a bit of extra cinnamon around for a lovely touch!
