1-First Step: Preheat oven to 350°F and grease a 9×5-inch loaf pan with butter or oil. Line with parchment for easy removal. This sets up for even baking in your cinnamon swirl quick bread recipe.

2-Second Step: In a large bowl, whisk 2 cups flour, 1 cup sugar, 1 tsp baking soda, and 1/2 tsp salt. This dry mix forms the backbone of your no yeast bread. Sift if lumps appear for smoother batter.

3-Third Step: In another bowl, beat 1 cup buttermilk, 1/2 cup oil, 2 eggs, and 2 tsp vanilla until smooth. For vegan adapts, prepare flax eggs ahead. Pour wet into dry and stir gently until just combined; overmixing toughens the easy cinnamon swirl bread.

4-Fourth Step: Mix 1/2 cup brown sugar and 2 tbsp cinnamon in a small bowl. Melt 1/3 cup butter. This filling creates the signature swirl in homemade cinnamon quick bread. Set aside for layering.

5-Fifth Step: Pour half the batter into the pan. Drizzle half the melted butter, then sprinkle half the cinnamon sugar mix. Swirl lightly with a knife for ribbons, not full mix. Add remaining batter, butter, and sugar; swirl again. This technique ensures distinct layers in simple no yeast cinnamon bread.

6-Sixth Step: Bake 50-60 minutes until a toothpick inserted in center comes out clean. Tent with foil after 30 minutes if browning too fast. Cool in pan 10 minutes, then transfer to wire rack. For gluten-free, bake 5-10 minutes longer.

7-Final Step: Whisk 1/2 cup powdered sugar with 1-2 tbsp milk for glaze. Drizzle over cooled bread. Slice and serve warm. Store as noted below. This completes your bread recipe, ready for any occasion.
