Few baked goods feel as comforting and timeless as a Moist Cinnamon Streusel Coffee Cake Loaf. With its tender crumb, rich cinnamon swirl, and buttery streusel topping, this loaf bridges the gap between breakfast and dessert effortlessly. Whether enjoyed with morning coffee, served at brunch, or sliced for an afternoon snack, this coffee cake loaf delivers cozy flavor in every bite.

Unlike traditional round coffee cakes, this loaf-style version is easier to slice, store, and serve. It’s also perfect for gifting, freezing, and baking ahead. The balance of soft vanilla cake, spiced cinnamon sugar, and crumbly streusel creates layers of flavor and texture that feel indulgent without being heavy.

This recipe focuses on moisture first. Sour cream (or yogurt), butter, and careful mixing ensure the loaf stays soft for days. The cinnamon streusel doesn’t just sit on top—it’s layered through the center, giving you that signature ribbon that makes coffee cake irresistible.

Instructions

Preheat your oven to 350°F (175°C). Grease and line a standard loaf pan with parchment paper.
In a medium bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon.
In a separate bowl, cream the butter, granulated sugar, and brown sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.

Gradually add dry ingredients, alternating with milk, mixing just until combined.
In a small bowl, combine streusel ingredients until crumbly.
Pour half of the batter into the loaf pan. Sprinkle half the streusel evenly over the batter.

Cool in the pan for 15 minutes, then transfer to a wire rack to cool completely.
