This Brown Butter Cinnamon Streusel Loaf combines the nutty depth of brown butter with a warm cinnamon swirl and crumbly streusel topping. It’s soft, moist, and finished with a simple vanilla glaze that makes every slice feel like a bakery treat. Easy to make, beginner-friendly, and perfect for cozy mornings, brunches, or holiday gatherings.
Preheat the oven to 350°F (177°C). Line a 9x5 inch loaf pan with parchment paper and lightly grease it.
Brown the butter in a small saucepan over medium heat. Stir until it foams and turns golden with brown flecks. Remove from heat and cool for five minutes.
In a large bowl, whisk together the brown butter, brown sugar, and granulated sugar. Add the eggs, vanilla, and milk, whisking until smooth.
In a separate bowl, combine the flour, baking powder, baking soda, salt, and cinnamon. Add this mixture to the wet ingredients and fold gently until just combined.
Mix the streusel topping ingredients in a small bowl until crumbly.
Spread half of the batter in the loaf pan. Sprinkle half of the streusel over it. Add the remaining batter and top with the rest of the streusel.
Bake for 28 to 35 minutes, or until a toothpick inserted in the center comes out clean or with a few crumbs. Begin checking at 28 minutes.
Cool in the pan for 10 minutes, then transfer to a cooling rack. Cool at least 20 minutes before glazing.
Whisk the powdered sugar, milk, vanilla, light brown sugar and salt until smooth. Drizzle over the cooled loaf.
Allow the glaze to set for 10 minutes before slicing.
