Cinnamon Swirl Streusel Loaf Cake

This cinnamon swirl streusel loaf could not be more perfect IMO. A deliciously moist loaf cake with swirls of cinnamon sugar and topped with the most perfectly crunchy streusel. Loaded with cinnamon and just so, so good.

INGREDIENT NOTES:

For the batter:

• All purpose flour: This is my go-to baking flour, but you could sub in gluten free flour if needed.
• Baking powder: Gives it the rise! Don't skip this!
• Cinnamon: It wouldn't be cinnamon loaf without cinnamon, right?!
• Salt: Never skip salt!
• Granulated sugar: Just a perfect hint of sweetness.
• Full fat plain Greek yogurt: This ingredient brings a ton of moisture and a little tang (but not too tangy, don't worry). You could use a lower fat content, but don't use flavored.
• Vanilla extract: Always!
• Eggs: Make sure these are room temp! If they're not perfectly room temp it's not horrible, just make sure they've at least sat out long enough to remove their fridge chill.
• Canola oil: You could also sub vegetable oil or any other neutral oil here.

For the filling:

• Cinnamon: This is where we want to really load in the cinnamon, so don't skimp on the quantity for this part.
• Granulated sugar: A classic cinnamon sugar combo! One of the best.

For the streusel:

• Butter: Unsalted! What's a streusel without butter? If you need to use salted butter that's fine, just add less salt.
• Brown sugar: I use light brown sugar but you could also use dark. Whatever you have!
• Granulated sugar: A nice balance with the brown sugar.
• All purpose flour: Helps form those beautiful streusel clumps.
• Cinnamon: More cinnamon for the cinnamon streusel loaf, of course!
• Salt: Just a bit - helps bring out the other flavors & help balance the sweetness.

HOW TO MAKE CINNAMON SWIRL STREUSEL LOAF:

This cinnamon swirl streusel loaf, like most others, are pretty simple in terms of putting them together!

You'll want to first add the dry ingredients into a medium bowl - flour, baking powder, cinnamon, salt. Then in a separate bowl, whisk together the granulated sugar, Greek yogurt, vanilla extract, eggs, and canola oil. Add the liquid mixture into the dry and combine!

In a small bowl, combine the cinnamon and sugar for the swirl.

For the streusel topping, in a medium microwave-safe bowl, melt the butter. To that bowl, add the granulated sugar, brown sugar, flour, cinnamon, and salt. Mix together with a fork until it comes together - it'll be kind of clumpy.

Prep a standard sized loaf pan by ensuring it is greased - whether that be spray, butter, ghee, use what you prefer. Put ⅓ of the batter into the loaf pan, and sprinkle ½ of the cinnamon sugar mixture evenly on top. Then follow with another ⅓ of the batter, followed with the other ½ of the cinnamon sugar mixture. Then top with the remaining ⅓ of batter. Finally, crumble up the streusel across the top of the batter evenly - you'll want some larger chunks and some smaller.

Bake for at 350℉ for 55-60 minutes until you can insert a knife into the center and it comes out clean. Serve warm or at room temperature. If you're looking for something super indulgent, serve with a scoop of vanilla or chocolate ice cream on top!

HOW TO STORE IT:

You can keep the loaf in an air-tight container at room temperature or in the fridge for about 5 days. You can also freeze it, wrapped tightly, for about 3 months.
