Cinnamon Swirl Loaf Cake

If you’re craving something sweet, cozy, and just a little indulgent, this Cinnamon Swirl Loaf Cake with Streusel Topping is your new go-to. It’s soft and buttery with a thick cinnamon swirl baked right in, topped with a brown sugar crumb that gets golden and crisp in the oven. Think coffee cake meets snickerdoodle vibes, but in loaf cake form.

Perfect for weekend brunch, afternoon coffee breaks, or gifting to a friend (if you can resist keeping it all to yourself).

Cinnamon Swirl Loaf Cake Ingredients

For the Streusel Topping:

• Brown sugar: Light or dark — your choice. Adds that deep molasses-y flavor to the crumb.
• All-purpose flour: For structure in the topping.
• Cinnamon: Warm, cozy spice that ties everything together.
• Softened butter: Creates those perfect crumbly, buttery chunks.

For the Loaf Cake:

• Butter: Softened so it creams beautifully with sugar.
• Granulated sugar: Sweetens the cake and helps with the soft texture.
• Eggs: Room temp is best for even mixing and fluffiness.
• Sour cream: Keeps the loaf moist and rich without being heavy.
• Neutral oil: A little bit helps keep the cake super soft.
• Vanilla extract: Adds classic, warm flavor.
• All-purpose flour, baking powder, baking soda, salt: Your dry mix to build structure and lift.

Cinnamon Swirl Loaf Cake Directions

1. Make the streusel: Combine flour, brown sugar, and cinnamon, then mix in softened butter until crumbly. Set aside.
2. Prep the pan and oven: Preheat to 350°F and line a 9×5 loaf pan with parchment.
3. Whisk dry ingredients: In a bowl, whisk flour, baking powder, baking soda, and salt.
4. Cream the butter and sugar: Beat until light and fluffy (about 2–3 minutes).
5. Add eggs and wet ingredients: One egg at a time, then mix in sour cream, oil, and vanilla.
6. Add dry to wet: Mix in the flour mixture in two parts, just until combined. Don’t overmix!
7. Make cinnamon batter: Scoop out half of the batter and stir in the cinnamon.
8. Layer and swirl: Alternate spoonfuls of plain and cinnamon batter into the pan. Swirl gently with a knife.
9. Top with streusel: Sprinkle the crumb topping generously over the top.
10. Bake: 55–65 minutes or until a toothpick comes out clean. Tent with foil if it’s browning too quickly.
11. Cool completely: Let cool in the pan for 10–15 minutes, then transfer to a rack.
12. Add glaze (optional): Drizzle cream cheese glaze over the cooled loaf before serving.

Tips for Success

• Use room temp ingredients for smooth mixing and better texture.
• Don’t overmix the batter — it can make the loaf tough.
• Use softened butter (not melted!) in the crumb topping for the best texture.
• Swirl gently — too much swirling will muddy the layers.
• Let it cool fully before glazing or slicing — it helps the crumb set and glaze stay put

FAQs

Can I make this ahead of time?
Absolutely! It tastes great the next day. Store it covered at room temp or in the fridge (especially if glazed).

Can I freeze it?
Yes! Freeze the whole loaf or individual slices (without glaze) for up to 2 months. Thaw at room temp.

Do I need to use the glaze?
Nope! The loaf is delicious on its own, but the cream cheese glaze definitely adds a bakery-style touch.

What kind of oil should I use?
Any neutral oil works—canola, avocado, or even light olive oil.

Can I bake this in a different pan?
A standard 9x5 loaf pan is best. If you use a smaller or larger pan, just adjust the baking time as needed.
