½ tsp baking soda
-
½ tsp salt
-
1 tsp cinnamon

-
1/3 cup melted butter (or oil)
-
1½ tsp vanilla extract

1 Tbsp melted butter
Optional donut topping:

🧁 Instructions
1. Prepare the loaf
-
Preheat oven to 350°F (175°C).
-
Grease a 9×5 inch loaf pan or line with parchment.
-
In a bowl, whisk together flour, sugar, baking powder, baking soda, salt, and cinnamon.
-
In a separate bowl, mix buttermilk, egg, melted butter, and vanilla.
-
Combine wet and dry ingredients—mix gently (don’t overmix).
2. Layer with cinnamon swirl
-
Pour half the batter into the pan.
-
Mix the swirl ingredients (brown sugar, cinnamon, melted butter).
-
Sprinkle or spoon half of the swirl over the batter.
-
Add remaining batter on top.
-
Finish with the rest of the swirl and drag a knife through the loaf a few times to marble it.
3. Bake
-
Bake 45–55 minutes, or until a toothpick comes out clean.
-
Cool 10 minutes in the pan.
4. Add the donut topping (optional but amazing!)
-
Brush the top with melted butter.
-
Sprinkle generously with cinnamon sugar.
This gives it that donut shop flavor and a delicate crunchy top.
⭐ Tips & Variations
-
Add a donut glaze: mix ½ cup powdered sugar + 1–2 tsp milk + pinch of cinnamon.
-
Swap-ins: Greek yogurt instead of buttermilk makes it extra moist.
-
Add-ins: ½ cup chopped apples or cinnamon chips.
-
Make muffins: bake 16–20 minutes at 350°F.
