Blackberry Brown Sugar Coffee Cake

The Best Blackberry Coffee Cake

This Blackberry Coffee Cake is dense and topped with a yummy brown sugar and cinnamon crumble and finished off with a sweet brown sugar glaze! Whether for breakfast, brunch, dessert, or as a cookout side, Blackberry Coffee Cake is perfect for any occasion.

In fact, you can try making and sharing it for the Fourth of July. It’s a wonderful way to showcase fresh-picked berries (even if you bought them … but I won’t tell).

You can even serve slices with vanilla ice cream or Homemade Whipped Cream for a cool summertime twist!

Ingredients For Blackberry Brown Sugar Coffee Cake

Cake – Unsalted butter, light brown sugar, large eggs, all-purpose flour, baking soda, ground cinnamon, kosher salt, sour cream, vanilla extract, and blackberries.

Crumble – Light brown sugar, all-purpose flour, ground cinnamon, and unsalted butter.

Glaze – Light brown sugar, vanilla extract, and water.

This recipe is soooo good!! We have tons of blackberry bushes, so I am always looking for ways to use them. The topping is incredible! I plan to double both the crumble AND the glaze when I make it again (probably tomorrow the way my family went through it!!)

How To Make Blackberry Coffee Cake

1. Begin by preheating the oven to 350° and greasing a 9×13-in baking dish with non-stick spray.
2. Start making the cake batter by creaming together the butter and brown sugar. Then, add in the eggs one at a time, beating after each addition.
3. In a large bowl, whisk together the flour, baking soda, cinnamon, and salt. Then, add half of the flour mix to the wet ingredients and beat until mixed.
4. Add the sour cream and vanilla extract and beat until mixed, then add the remaining flour mixture and beat until everything is well incorporated.
5. Pour half of the batter into the baking dish and evenly spread the blackberries out in a layer on top of the batter. Then pour the rest of the batter over the blackberries, making sure to fully cover them.
6. Prepare the crumble topping by combining the ingredients in a large bowl or stand mixer and beating until crumble forms, spread evenly over cake batter. Bake for 40 to 45 minutes or until a cake tester or toothpick inserted into the center of the cake comes out clean.
7. Once the cake is done baking, remove from the oven and begin making the glaze. Whisk together the glaze ingredients and drizzle over the top of the warm coffee cake. Allow the glaze to cool and harden for about 10 minutes before slicing and serving.

Storage Instructions

This treat is best served fresh but should keep for 1 to 2 days covered at room temperature or 3 to 4 days if it’s covered and placed in the fridge. With that said, after a few days, the cake may begin to get mushy from the moisture of the berries.

How To Freeze Coffee Cake

You can store a tightly-wrapped Blackberry Coffee Cake in the freezer for two to three months. First, wrap the cake in saran wrap, then wrap it in aluminum foil, then place it in a two-gallon freezer bag.

When you’re ready to enjoy, simply let the cake thaw on the counter at least 12 hours before serving. One thing to note about freezing this cake is that you will likely want to cut it into smaller portions because it will be difficult to wrap it when it’s whole.
