Stop Just Adding Zest: The “Spatula Trick” That Unlocks 10x More Flavor in Your Blackberry Cake
I’m all about berry cake, and I know you love them too! Our cranberry orange cake and peach blueberry cake are two popular cakes with a 5 star rating. This new blackberry coffee cake recipe combines lemon and blackberry flavor in a 9″ round cake with an easy streusel topping.
To get the most out of your citrus, don’t just toss the zest into the bowl. Massage it. By pressing the lemon zest into the white sugar with a spatula, you are releasing the essential oils directly into the sugar, which intensifies and helps to equally distribute lemon flavor. You can also use this secret on our lemon raspberry cake and cranberry orange muffins.

Ingredients

Fresh blackberries are best. I have not tested this with frozen berries.
You may use Greek yogurt in place of the sour cream if you prefer.

How to Make Blackberry Coffee Cake: Step by Step
In a mixing bowl, make the crumb topping by combining the flour, brown sugar, salt and cinnamon. Drizzle in the melted butter and mix to combine.

In a different mixing bowl, whisk together the 2 cups of flour, baking powder, baking soda and salt. Set aside.
In a large bowl, add the sugar and lemon zest. Gently press the zest into the sugar with a silicone spatula so that the sugar absorbs the oils from the zest.

Add the butter and cream together with a hand mixer (or stand mixer with the paddle attachment) until fluffy in texture, about 3-4 minutes. Add the eggs on at time, beating in between each egg. Then add the vanilla and combine. Fold in the sour cream until the mixture is well combined. Sprinkle the flour mixture into the wet ingredients and mix until just combined.

Place the roughly chopped blackberries in a small bowl. Sprinkle the remaining tablespoon of flour over the berries and toss to combine.

Gently fold the chopped blackberries into the cake batter. Spread the batter into an even layer in the prepared pan.

Crumble the topping over the cake, covering it evenly. Bake for 37-40 minutes. A toothpick inserted into the center of the cake should come out mostly clean. Let the cake rest for 5 minutes, then remove the springform. Continue to cool for 15 minutes.

Make the glaze by mixing the lemon juice into the powdered sugar until smooth and runny. Drizzle over the top of the blackberry coffee cake generously.
