What Is A Coffee Cake?

A coffee cake is a simple, sweet cake meant to be enjoyed with a cup of coffee or tea. Unlike other cakes, they are not frosted but they are often topped with streusel or another crumbly topping with a drizzle of icing. This breakfast treat comes in a variety of flavors ranging from classic cinnamon to raspberry cream cheese to blueberry.

Coffee Cake vs Streusel vs Buckle Cake

Coffee cake is a broad term referring to any cake meant to be enjoyed with coffee (or tea). Streusel refers to a crumbly mixture of sugar, fat (often butter), and flour used to fill and/or top baked goods. It also often includes nuts and spices, but not necessarily. A buckle cake is a cake that has fruit folded into the batter and streusel on top. Many buckle cakes, like this one, can also be deemed coffee cakes because they are meant to be enjoyed with coffee.

All-Purpose Flour - Feel free to use your favorite 1:1 gluten-free flour instead.

Cake

All-Purpose - You can use your favorite 1:1 gluten-free flour instead.
Baking Powder
Salt
Salted Butter - Make sure your butter is at room temperature. It will not cream properly with the sugar if it is too cold.
Granulated Sugar
Light Brown Sugar - Looking for a richer flavor? Try dark brown sugar instead.
Large Eggs - The eggs must be at room temperature, they will incorporate into the batter more easily, helping prevent over-mixing.
Pure Vanilla Extract
Sour Cream - Allow the sour cream to come to room temperature before incorporating it into the batter. It will mix in much more easily and help prevent you from overmixing.
Fresh or Frozen Blueberries - You can use a different berry if you'd like. Raspberries and/or blackberries would be a great choice.
All-Purpose Flour - This is to coat the berries so that they are suspended in the batter as opposed to sinking to the bottom.
Blueberry Jam - You are more than welcome to use a different jam here. Get creative! If you love jam then check out my peanut butter and jelly cookies.

Tips for Success

Are you ready to make the best blueberry coffee cake you have ever tasted? Follow these simple tips and tricks and you won't be disappointed.

Room temperature ingredients. When making the batter for this blueberry coffee cake with sour cream it is crucial that the butter, eggs, and sour cream are all at room temperature. If they are not, they will not mix easily with the other ingredients, which will lead to over-mixing. The butter for the streusel should also be at room temperature so that it blends well with the flour, cinnamon, and sugar.
Don't over-mix the batter. Over-mixing the batter will cause the glutens in the flour to overdevelop, ending you with a dense, tough cake.
Toss the blueberries in flour. If you skip this step, the blueberries will sink to the bottom of the coffee cake as opposed to being suspended throughout.
Toothpick test. Because this cake is covered in streusel, it can be hard to tell when it is done. To be safe, use a toothpick to poke the center of the cake. If it comes out clean, the cake is done. If it comes out gooey, give this blueberry dessert a few more minutes in the oven.

Instructions

Streusel Topping

Preheat the oven to 350F/180C and line a 9-inch square baking pan with parchment so that the parchment paper overhangs on the sides, this will help you pull the baked cake out of the pan later. Grease the parchment with non-stick baking spray and set aside.
In a medium bowl whisk together the flour, brown sugar, and cinnamon. Use your clean fingers and blend in the butter and use a spatula to mix it all together to moisten everything, this will take a couple of minutes, you want a wet sand texture, and thick clumps are good. Set it in the refrigerator while you prepare the cake.

Cake

In a large bowl whisk together the flour, baking powder, and salt.
In the bowl of an electric stand mixer fitted with a paddle attachment or a large bowl with a handheld electric whisk beat the sugar and butter together for 2-3 minutes, scrape down the bowl after the first minute then continue mixing. You want a light fluffy mixture.
Add the eggs, one at a time, scraping down the bowl after each addition and making sure the egg is fully combined, there should be no trace of egg yolk. In a separate bowl mix together the vanilla extract and sour cream.
Gently fold in ⅓ of the dry ingredients until just almost combined, then gently fold in ½ of the sour cream until just combined, then repeat with ⅓ of the dry, the rest of the sour cream, and finish with the remaining flour. Do not over-mix.
In a separate bowl toss the blueberries and flour together, coating the blueberries helps prevent them from sinking. Gently fold the blueberries into the cake batter, do not over-mix as the blueberries will bleed their color.
Add the cake batter to the prepared pan then drop dollops of blueberry jam on top and use a butter knife to swirl it into the batter. Sprinkle all of the crumble on top into an even layer. Bake for 40-50 minutes, since the cake is covered in a crumble it is best to check by using a toothpick test, insert a toothpick into the center of the cake, moist crumbs are okay but if there is any wet batter the cake will need to cook longer.
Let the cake cool on a wire rack for at least 30 minutes before using the parchment overhang to gently and quickly remove it from the pan. Best served the day it is made but leftovers will last in an airtight container for up to 3 days.
