FAQs
Can I use frozen blackberries?
Yes, but thaw and drain them first to prevent excess moisture in the cake batter.
Can I make this with a cake mix?
You could, but making the batter from scratch ensures enough structure and flavor, especially when working with juicy blackberries.
Can I bake this in a bundt pan?
Yes! A bundt pan gives a beautiful shape, but be sure to adjust your bake time and thoroughly grease the sides of the bowl and the bottom of the pan.
Blackberry Coffee Cake Step by Step
Ingredients
For the Streusel Topping
- 1/2 cup brown sugar
- 1/2 cup all-purpose flour
- 1/4 cup melted butter
- 1/2 tsp cinnamon
For the Cake
- 1/2 cup butter, at room temperature
- 1 cup sugar
- 2 large eggs
- 1 tsp vanilla extract
- 1/2 cup sour cream
- 1 tbsp lemon juice
- 2 cups all-purpose flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1 1/2 cups fresh blackberries
Preparation
Preheat oven to 350°F. Lightly coat a springform pan, square pan, or round cake pan with cooking spray and line with parchment paper for easy removal.
Combine all of the streusel ingredients in a small bowl using a pastry blender or fork until coarse crumbs form then set aside.
In a medium bowl, whisk together the dry ingredients: flour, baking powder, baking soda, and salt then set aside.
In a large mixing bowl or the bowl of a stand mixer fitted with the paddle attachment, cream butter and sugar until light and fluffy (about 2–3 minutes) on medium speed.
Beat in eggs one at a time, then mix in vanilla extract, sour cream, and lemon juice until smooth.
Reduce the speed to low and gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Gently fold in the juicy blackberries with a spatula. If your berries are especially large, consider halving them so they distribute more evenly.
Spread the batter into the prepared pan.
Sprinkle the crumb mixture on top.
Bake for 45 minutes or until a cake tester inserted into the center of the cake comes out with just a few moist crumbs attached.
Let cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely.
Blackberry Coffee Cake Leftovers
Storage: Once your blackberry coffee cake has fully cooled on a wire rack, transfer any leftovers to an airtight container. It will stay fresh at room temperature for up to 2 days, or in the refrigerator for up to 5 days. If your kitchen is particularly warm or humid, refrigeration is the best option to preserve the moisture in the cake batter and keep the crumb topping from becoming soggy. For best results, place a piece of parchment paper between layers to prevent sticking.
Reheating: To reheat, simply warm individual slices in the microwave for 15–20 seconds. This helps bring back the soft, tender texture and enhances the flavors of the plump blackberries and streusel topping. If you prefer a crispier top, you can reheat slices in a toaster oven at 300°F for about 5 minutes. Serve with a cup of coffee or vanilla ice cream for a little something extra during your afternoon coffee break.
Freezing: This easy blackberry coffee cake also freezes beautifully. Wrap individual slices or the entire cake tightly in plastic wrap, followed by a layer of aluminum foil to prevent freezer burn. You can also store it in a freezer-safe airtight container. It will keep for up to 2 months. To enjoy, let it thaw overnight in the refrigerator, then bring to room temperature or gently warm it in the oven. Freezing does slightly soften the crumb mixture, but the moist crumbs and juicy blackberries still shine through.

I enjoyed the way you walked through the layers of this cake, especially how the blackberries melt slightly into the batter while the topping stays crisp. It gave me a clear picture of that soft centre with the sweet crumble on top. I am tempted to try this with a little mix of berries since I usually have a few leftover from the week.

Coffee cake is one of my favorite brunch items, especially during the holiday season. I’ve never incorporated blackberries before.
