Method
- Preheat oven to 350°F (175°C). Grease and flour a 9x5-inch loaf pan or line with parchment paper.
- In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
- In a large bowl, cream softened butter and granulated sugar with an electric mixer until light and fluffy, about 2-3 minutes.
- Beat in eggs one at a time, then mix in vanilla extract.
- With mixer on low, add dry ingredients and sour cream alternately, beginning and ending with flour. Mix until just combined.
- For the filling, mix brown sugar, flour, and cinnamon. Stir in melted butter until mixture is crumbly.
- Spread half the batter in the prepared pan. Sprinkle with two-thirds of the cinnamon filling. Top with remaining batter and spread carefully. Sprinkle remaining filling on top.
- Use a knife to gently swirl the batter. Bake for 50-60 minutes, until a toothpick comes out with moist crumbs. Cool in pan 20 mins, then transfer to a wire rack to cool completely.
- For the glaze, whisk powdered sugar, milk, and vanilla until smooth. Drizzle over cooled bread before slicing.
Notes
For best results, ensure all ingredients are at room temperature. Do not overmix the batter. The bread must be completely cool before glazing and slicing for clean cuts.
