Step-by-Step Instructions
Prepare the Pan
Preheat your oven to 350°F (175°C).
Grease a standard 9 × 5-inch (23 × 13 cm) loaf pan.
Line the pan with parchment paper, leaving some overhang on the long sides.
The parchment makes the finished loaf much easier to remove.
Make the Cinnamon Streusel
Add the brown sugar, flour, and cinnamon to a medium bowl.
Whisk until evenly combined.
Add the cold cubed butter.
Use your fingertips or a pastry cutter to work the butter into the dry ingredients until coarse crumbs form.
Do not completely melt or blend the butter into the mixture.
Place the streusel in the refrigerator while preparing the cake batter.
Prepare the Cake Batter
In a large bowl, whisk together the flour, granulated sugar, baking powder, and salt.
In another bowl, whisk the melted butter, eggs, milk, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients.
Gently fold everything together with a spatula until just combined.
Do not overmix the batter.
A few small lumps are perfectly fine.
Assemble the Loaf
Pour approximately half of the batter into the prepared loaf pan.
Spread it evenly.
Sprinkle a generous layer of cinnamon streusel over the batter.
Pour the remaining cake batter over the streusel.
Gently spread the batter with a spatula.
Finish with the remaining streusel, distributing it evenly across the top.
Bake
Place the loaf in the center of the preheated oven.
Bake at 350°F (175°C) for 50–55 minutes.
The loaf is ready when a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
If the top begins browning too quickly, loosely cover it with aluminum foil during the final 15 minutes.
Cool the Cake
Remove the loaf from the oven.
Allow it to cool in the pan for approximately 15 minutes.
Use the parchment paper to carefully lift the cake from the pan.
Transfer it to a wire rack.
Allow it to cool for another 15–20 minutes before glazing.
Make the Vanilla Glaze
Place the powdered sugar in a small bowl.
Add 1 tablespoon of milk or heavy cream and the vanilla extract.
Whisk until smooth.
If the glaze is too thick, add the remaining liquid a few drops at a time.
If it becomes too thin, add a little more powdered sugar.
Glaze and Serve
Drizzle the vanilla glaze over the cooled loaf.
Allow the glaze to set for approximately 10 minutes.
Slice and serve.
Best Tips
Use room-temperature eggs and milk for a smoother batter and more even baking.
Measure flour carefully. Too much flour can make the loaf dense and dry.
Keep the butter cold when preparing the streusel so it forms distinct crumbs.
Do not overmix the cake batter. Mix only until the ingredients are incorporated.
Allow the loaf to cool before adding the glaze so the glaze stays on top instead of melting into the cake.
For clean slices, use a sharp serrated knife and gently saw through the loaf.
Best Ingredient Options
Flour: All-purpose flour works perfectly for this recipe. Avoid replacing it with bread flour because the higher protein content can make the cake tougher.
Butter: Unsalted butter gives you better control over the salt level. Salted butter can also be used by reducing the added salt slightly.
Milk: Whole milk provides the richest texture. You can substitute it with 2% milk.
Cinnamon: Fresh, aromatic ground cinnamon gives the strongest flavor.
Vanilla: Pure vanilla extract provides excellent flavor, but vanilla bean paste can be used for a more intense vanilla taste.
Brown sugar: Light brown sugar gives a delicate caramel flavor. Dark brown sugar can be used for a deeper molasses taste.
Recipe Variations
Cinnamon Swirl Loaf
Mix 2 tablespoons brown sugar and 1 teaspoon cinnamon together.
Sprinkle the mixture between the two layers of cake batter for an extra cinnamon swirl.
Apple Cinnamon Loaf
Fold 1 cup (120 g) peeled and finely diced apple into the cake batter.
Firm apples such as Granny Smith work particularly well.
Pecan Streusel Loaf
Add ½ cup (60 g) finely chopped pecans to the streusel.
The nuts add extra crunch and a delicious toasted flavor.
Chocolate Chip Version
Fold ½ cup (85 g) semi-sweet chocolate chips into the batter.
The combination of chocolate, cinnamon, and vanilla makes an especially indulgent dessert.
Cream Cheese Glaze
Replace the regular vanilla glaze with a simple cream cheese glaze made with softened cream cheese, powdered sugar, vanilla, and a little milk.
What to Serve With
Serve a slice with freshly brewed coffee for a classic afternoon treat.
Tea, hot chocolate, or a glass of cold milk also pair beautifully with the cinnamon flavor.
For brunch, serve smaller slices alongside fresh berries and yogurt.
A scoop of vanilla ice cream can turn a warm slice into an easy dessert.
Make-Ahead Instructions
The loaf can be baked 1 day ahead.
Allow it to cool completely before covering it tightly.
For the freshest presentation, prepare the glaze separately and drizzle it over the loaf shortly before serving.
The streusel mixture can also be prepared several hours ahead and kept refrigerated.
Storage
Store the completely cooled loaf in an airtight container at room temperature for up to 3 days.
For longer storage, refrigerate it for up to 5 days.
Allow refrigerated slices to sit at room temperature for about 15–20 minutes before serving for the best texture.
Reheating
For a warm slice, microwave it for approximately 10–15 seconds.
You can also place slices in a 300°F (150°C) oven for about 5–8 minutes.
Avoid overheating because the cake can become dry.
Freezing
The loaf freezes very well when properly wrapped.
For best results, freeze the loaf without the glaze.
Wrap it tightly in plastic wrap, followed by aluminum foil, and place it in a freezer-safe bag or container.
Freeze for up to 3 months.
Thaw overnight in the refrigerator or for several hours at room temperature.
Prepare fresh glaze before serving.
Common Mistakes to Avoid
Overmixing the Batter
Overmixing develops too much gluten and can result in a dense loaf.
Mix only until the flour disappears.
Using Warm Butter in the Streusel
The butter for the streusel should be cold.
Warm or melted butter can create a greasy mixture instead of distinct crumbs.
Measuring Too Much Flour
Too much flour is one of the easiest ways to create a dry cake.
For the most accurate results, use a kitchen scale.
Removing the Cake Too Quickly
The loaf is delicate while hot.
Allow it to cool for about 15 minutes in the pan before lifting it out.
Glazing a Hot Cake
A very hot cake can cause the glaze to melt and disappear.
Wait until the loaf is warm or completely cool before glazing.

Frequently Asked Questions
Can I use a different loaf pan?
Yes. An 8½ × 4½-inch loaf pan can also work, although the batter will be deeper and the baking time may need to increase slightly.
Watch the cake carefully and test the center with a toothpick.
Why did my loaf sink in the middle?
A loaf can sink if the batter is overmixed, the oven temperature is too low, or the cake is removed before it has fully baked.
Make sure the center is fully set before removing it from the oven.
Can I make this recipe without the glaze?
Absolutely.
The cinnamon streusel provides plenty of flavor, so the glaze is optional.
How do I make the streusel extra crunchy?
Keep the butter cold and avoid overworking the mixture.
You can also add chopped pecans or walnuts for additional crunch.
Can I use almond milk?
Yes. Unsweetened almond milk can replace the whole milk, although the loaf may be slightly less rich.
Can I add fruit?
Yes. Diced apples, blueberries, or finely chopped pears can work beautifully.
Keep added fruit reasonably dry to avoid introducing too much moisture into the batter.
How can I get bakery-style slices?
Let the loaf cool completely before slicing.
Use a sharp serrated knife and clean the blade between cuts.
