1. Preheat your oven to 350°F (175°C). In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.

2. Beat in the eggs one at a time, then stir in the vanilla and almond extract. Mix in the sour cream until well combined.

3. In a separate bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. Gradually add this to the wet mixture, mixing until just combined.

4. Grease a 9×5-inch loaf pan or line it with parchment paper. Pour the batter into the pan and smooth the top. Sprinkle generously with the cinnamon-sugar mixture.

5. Bake for 50 to 60 minutes or until a toothpick inserted into the center comes out clean. Let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
