Why We Love This Blueberry Lemon Coffee Cake

Simple ingredients and simple prep. A lot of pantry and kitchen staples in this recipe make it one that I can usually put together in a pinch if needed. We always have lemons on hand and blueberries in the freezer so it’s a good one beyond just for special occasions.

So refreshing. There’s always room for coffee cakes with warm and cozy spices and flavors, but a coffee cake recipe with vibrant lemon flavor and fresh berries is great when the weather is warm and the sun is shining is the perfect breakfast recipe!

The perfect brunch dish for a special gathering. This is a favorite for special gatherings. Easter brunch, baby showers, and more. Blueberry and lemon are always a favorite flavor combination and this one is the hit at the party!

Freezer friendly! While coffee cake is always served fresh, it doesn’t keep very well for too long. We like to freeze half and find that it still has great flavor and texture after freezing!

Ingredient Notes

Ingredients needed to make recipe arranged on surface.

flour: all purpose flour, measured by weight for best results.
baking powder: make sure it is FRESH–you do not want to make this dish with expired or baking powder that is not at its freshest.
sugar: white sugar–you can lessen the amount used if you don’t want your coffee cake to be too sweet.
butter: unsalted butter is the preference in this cake, but if that is all you have, you can use it and then half the amount of salt later in the recipe.
vanilla: use vanilla extract versus the imitation vanilla in this recipe if possible. I don’t find that lemon extract is also needed in this coffee cake as the lemon flavor is already pretty strong, but you can add a drop or two on top of the vanilla if desired.
sour cream: for best results, use full fat sour cream and make sure it is at room temperature.
lemon juice: freshly squeezed lemon juice is a must in this tender coffee cake–do not use the bottled lemon juice. It will not produce the same level of flavor.
blueberries: fresh blueberries are my personal favorite, however you can use frozen blueberries, just do not thaw them before adding to the recipe

Step-By-Step Instructions

Melted butter added to dry ingredients in bowl.

Step 1: In a small bowl, whisk the flour, sea salt and brown sugar together for the streusel.

Step 2: Add in the butter and stir to combine until mixture is moist but crumbly. Chill until ready to add to coffee cake.

Step 3: Whisk together the flour, baking powder and salt to combine. Set aside. Using an electric hand mixer or stand mixer, cream butter and sugar until smooth, light and fluffy in a large mixing bowl. Add in the eggs and vanilla and beat to fully incorporate into the mixture.

Sour cream, lemon zest and lemon juice added to bowl with wet ingredients.

Step 4: Add the room temperature sour cream, lemon juice and lemon zest and beat just until incorporated.

Step 5: Slowly add the flour mixture into the wet ingredients and beat only until mixed in.

Step 6: Toss the blueberries with about 1 tablespoon of flour to coat (this will help keep them from sinking to the bottom of the cake).

Step 7: Gently fold the berries into the lemon cake batter.

Step 8: Line a 9×9 inch baking pan or 9-inch springform pan with parchment and grease the sides. Transfer the batter to the pan and spread evenly. It will be thick!

Step 9: Remove the streusel topping from the refrigerator and use a fork to help break it into small pieces and then sprinkle over top of the cake batter evenly.

Step 10: Bake the coffee cake for about 40-50 minutes or until a toothpick comes up clean in the center of the cake and the top of the buttery crumble is golden brown. Make sure when testing to see if the cake is done, not to confuse blueberry juice for the cake still being uncooked. Find a spot where there aren’t many berries to poke!

Step 11: Allow the coffee cake to cool for about 10-15 minutes and while it cools, whisk together the icing ingredients to desired thickness. Drizzle over top of the cake and serve immediately!

Recipe Tips

Use room temperature ingredients. For the cake batter in this lemon blueberry coffee cake recipe, you want room temperature butter, sour cream, and eggs for best results. This will allow the batter to be extra smooth and bonded together in a creamy mixture versus lumpy.
Don’t over mix the batter. Over mixing cake batter, especially once the dry ingredients are added can make for a tough textured cake, and no one wants that!
This batter is pretty thick, and that is ok! Don’t be worried if the batter seems to be pretty thick. That is the way it is and will produce a dense, tender coffee cake!

Storage

For best results, store your blueberry lemon coffee cake at room temperature in an airtight container. It will keep for about 2-3 days and have optimal moisture.

You can refrigerate your coffee cake for about 5-7 days. I find it is not as moist when stored in the fridge, but microwaving it for about 15 seconds helps.

You can freeze leftovers for up to 3 months. Allow the cake to cool completely. Double wrap the cake with plastic wrap and then foil or a freezer safe bag or container. Allow to thaw at room temperature before eating.
