This cozy apple cider donut bread packs the classic cinnamon-sugar donut flavor into a tender, buttery loaf. With real apple cider reduced for bold flavor and a sparkling cinnamon-sugar finish, it’s perfect for breakfast, snacks, or fall gatherings.
Preheat oven to 350°F. Grease a 9×5 inch loaf pan and line with a parchment sling.
Reduce the cider: Add apple cider to a small saucepan. Simmer over medium heat until reduced to about 0.5 cup, 8 to 12 minutes. Cool to lukewarm.
Whisk dry ingredients: In a large bowl, whisk flour, baking powder, baking soda, cinnamon, nutmeg, and salt until evenly combined.
Mix wet ingredients: In a separate bowl, whisk granulated sugar, brown sugar, eggs, melted butter, buttermilk, vanilla, and the cooled reduced cider until smooth.
Combine: Pour wet ingredients into the dry. Fold gently with a spatula until just combined; do not overmix.
Bake: Spread batter into the prepared pan and smooth the top. Bake 48 to 55 minutes, or until a toothpick inserted in the center comes out clean.
Cool: Let the loaf cool in the pan for 10 minutes, then lift out to a rack.
Make topping: Stir 0.25 cup sugar with 1 tsp cinnamon. Brush the warm loaf all over with 2 tbsp melted butter, then sprinkle and pat the cinnamon-sugar onto the top and sides.
Cool completely before slicing into 10 slices. Serve slightly warm or at room temperature.
Notes
Use fresh apple cider (not apple cider vinegar). If you can’t find cider, apple juice works but flavor will be milder. Store airtight at room temperature for 2 days or refrigerate up to 5 days; freeze sliced for up to 2 months.
