A delightful cinnamon swirl loaf with a tender crumb and a sweet cinnamon sugar filling.
Preheat your oven to 350°F (175°C) and grease a loaf pan.
Greasing the pan ensures the loaf doesn't stick and comes out cleanly.
In a mixing bowl, combine the flour, baking soda, salt, and cinnamon.
Mixing the dry ingredients first ensures even distribution of the leavening agent.
In another bowl, whisk together the oil, sugar, egg, and buttermilk until smooth.
Ensure the wet ingredients are well combined for a smooth batter.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Avoid overmixing to keep the loaf tender.
In a small bowl, mix the brown sugar and cinnamon for the filling.
Using brown sugar adds a rich, caramel-like flavor to the filling.
Pour one-third of the batter into the prepared pan, then sprinkle one-third of the filling over it. Repeat this layering process two more times.
Layering creates the signature swirl pattern in the loaf.
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Check the loaf at 50 minutes to avoid overbaking.
Let the loaf cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Cooling on a wire rack prevents the bottom from becoming soggy.
Slice and serve your cinnamon swirl loaf. Enjoy!
Serve with a pat of butter or a drizzle of icing for extra indulgence.
