A coffee break never tasted this good.

Now that we have gone through the ingredients list, it’s time to put them all together and make this delicious Buttermilk Streusel Coffee Cake Recipe. Follow these step-by-step instructions to create a perfect cake.

Step 1: Prepare the Pan

To start, you will need to prepare an 8×8 inch square baking pan by coating it with non-stick spray or butter. Then, dust the pan with flour or graham cracker crumbs. This is important because it will prevent the cake from sticking to the pan while also giving it a delightful texture.

Step 2: Make the Streusel Topping

Making the streusel topping is easy. Add brown sugar, walnuts, cinnamon, rolled oats, and flour to a bowl. Mix them together until everything is combined. Then, add in chilled butter and use your hands to work it into the mixture until you have a crumbly texture. Set this aside until you need it again in Step 5.

Step 3: Preheat Your Oven

Before getting started on mixing the batter for the cake, make sure to preheat your oven to 350°F (180°C). This will help ensure that your cake bakes evenly and thoroughly.

Step 4: Combine Dry Ingredients

In a large mixing bowl, combine all-purpose flour, granulated sugar, baking powder, baking soda, salt and nutmeg. Mix everything together until they are fully incorporated.

Step 5: Prepare Cake Batter

In another bowl, you want to whisk together your wet ingredients (buttermilk, melted unsalted butter, vanilla extract and eggs). Once mixed properly pour wet ingredients into dry ingredients mix and stir well using a whisk or spatula. Be careful not to overmix as this may lead to a tough cake.

Step 6: Create Layers

Time to create the layers! Pour half of the cake batter in your prepared pan. Then, add a layer of the cinnamon streusel mixture on top of the batter. Repeat this again by adding the remaining batter on top, once done sprinkle any extra streusel mixture on the top layer.

Step 7: Bake to Perfection

Put the pan in the oven and bake your buttermilk streusel coffee cake for 35-40 minutes or until a toothpick inserted comes out clean. Take it out from the oven once done and let it cool before slicing it.

Now you have finished creating your masterpiece! A buttermilk streusel coffee cake made from scratch. Enjoy it with a cup of coffee, tea, or milk as a morning treat, afternoon snack, or whenever you crave something sweet!

When it comes to serving this buttermilk streusel coffee cake, the options are endless. This sweet treat is perfect for a cozy morning in or an afternoon tea with friends.

One way to serve it is warm out of the oven with a dollop of whipped cream or a scoop of vanilla ice cream on top. The heat from the cake will melt the cream or ice cream, creating a delicious creamy melange with the crumbly streusel.

If you want a lighter option, try pairing it with fresh fruits like strawberries, raspberries, or blueberries. The acidity from the fruits will cut through the richness of the cake and balance the sweetness.

For those who prefer a more decadent experience, pair it with a cup of freshly brewed coffee or hot chocolate. The bitterness from the coffee/espresso or cocoa powder will complement the sweetness of the cake and enhance its flavors.

Moreover, consider indulging in some DIY latte art – an elegant design made by pouring steamed milk into a shot of espresso mixed with sugar syrup or caramel flavoring. As you take your first mindful sip with your lips & taste buds tingling – you’ll revel in the perfect combination of brewed goodness and baked delicacy.

Lastly, if you’re feeling adventurous, try topping it with some savory toppings like bacon, scrambled eggs, or smoked salmon for a unique brunch experience.

Now that you have all the ingredients and steps needed to make a mouthwatering buttermilk streusel coffee cake, it’s time to talk about some tips to ensure that your cake recipe is executed perfectly.

Firstly, when measuring the ingredients, make sure to use leveled measuring cups when scooping flour or sugar. This ensures that you are getting the exact amount required for the recipe, and will prevent the cake from being too dry or runny.

In addition, you can add extra streusel toppings on your buttermilk coffee cake if you prefer crumbly and buttery layers running through your entire cake. From experience, adding more crumble than the recipe requires enhances the overall taste and texture of the cake.

Another useful tip is to keep a close eye on your baking soda and baking powder portions. Too much of these leavening agents can cause the cake to rise too quickly resulting in a dome-shape top or sink in the middle. Balancing these ingredients is key to achieving a beautiful flat, golden brown cinnamon streusel on top of your buttermilk coffee cake.

When making your cinnamon streusel topping, ensure that it is finely mixed and clumpy with no lumps whatsoever. This will control moisture and avoid the topping from sinking into the cake during baking.

To create an extra dimension of flavor, you can also add apple chunks or blueberries into the batter for a fruity twist of taste in your buttermilk streusel coffee cake. With every bite, enjoy bits of soft dough mixed with juicy fruits complimented by a crispy layer of cinnamon goodness on top.

Lastly, remember that baking time varies according to altitude and oven type so be sure to check up periodically as you bake. It’s best to test doneness by inserting a toothpick into the center of the cake at least 5 minutes before recommended bake time has elapsed. If it comes out clean, then your buttermilk streusel coffee cake is ready!

By following these tips, you will be ensured of a perfectly executed coffee cake recipe with a crumbly cinnamon streusel that’s the perfect way to start your day.


Now, we have reached item (9) on our recipe article section – the frequently asked questions.

That’s why I’ve included this section to help answer some of the questions that may be lingering on your mind about this buttermilk streusel coffee cake recipe. So, let’s dive in!

What’s the difference between coffee cake and streusel?

When it comes to cakes, the amount of streusel topping is what sets crumb cake apart from coffee cake. Generally, crumb cake has a more generous amount of streusel whereas coffee cake can be made without it altogether.

What is the difference between coffee cake and crumble cake?

When it comes to cakes with streusel topping, crumb cake and coffee cake have notable differences. The main difference is the thickness of the streusel layer, with crumb cake having a thicker layer as compared to coffee cake. While coffee cake can also be made without the streusel topping, it is a defining characteristic of crumb cake. Additionally, there is a variant of crumb cake called the New York-style crumb cake, which has larger crumbs.

What does buttermilk do in cakes?

When it comes to enhancing the texture and flavor of baked goods, buttermilk plays a crucial role. It’s renowned for its ability to tenderize, adding a touch of moisture and richness to the mix. Although the tanginess of buttermilk is subtle in many recipes, it significantly contributes to the taste of some, such as the vanilla buttermilk cake, keeping it from being overly sweet while imparting a delightful buttery flavor.

What makes a cake more moist buttermilk or sour cream?

When it comes to baking, sour cream can be a game-changer. Thanks to its velvety consistency, sour cream can keep baked treats from drying out, especially those that tend to come out a little parched, like sponge cakes. Let’s explore how you can enhance your baked goods with the help of sour cream.
