A soft, buttery cake studded with juicy blackberries sits under a smooth layer of tangy cream cheese, and the whole thing gets finished with a blanket of cinnamon brown sugar crumbs. This blackberry crumb cake with cream cheese is the kind of bake that turns an ordinary morning into something worth waking up for.

Instructions
Preheat oven to 350°F (177°C). Grease a 9-inch springform pan and line the bottom with parchment paper.
Beat softened butter and ¾ cup sugar until light and fluffy, about 2-3 minutes. Add eggs one at a time, then mix in vanilla and sour cream.
Whisk together flour, baking powder, baking soda, and salt. Gradually add dry ingredients to wet mixture, mixing just until combined.
Toss blackberries with 1 tablespoon flour, then gently fold them into the batter. Spread evenly into the prepared pan.
Beat cream cheese and ¼ cup sugar until smooth. Add egg and vanilla, mixing until no lumps remain.
Spoon dollops of cream cheese mixture over the batter and gently spread into an even layer using an offset spatula.
Whisk flour, brown sugar, cinnamon, and salt. Cut in cold cubed butter until the mixture resembles coarse, pea-sized crumbs.
Sprinkle crumb topping evenly over the cream cheese layer. Scatter extra blackberries on top for visual appeal.
Bake for 55-65 minutes. Tent with foil at the 40-minute mark if browning too quickly. Cake is done when center no longer jiggles.
Cool in the pan for 30 minutes before releasing the springform sides. If using glaze, whisk powdered sugar and lemon juice and drizzle over the warm cake.
Notes
Use room temperature ingredients – cold cream cheese or eggs will not blend smoothly and can leave lumps in the batter.
Toss berries in flour – this simple step keeps the blackberries suspended in the batter instead of sinking to the bottom.
Keep the butter cold for the crumb topping – cold butter is what creates those craggy, crisp crumbs instead of a flat, greasy layer.
Do not rush the cooling time – slicing too early can cause the cream cheese layer to ooze out.
Tent with foil if needed – this protects the top from over browning while the center finishes baking.
Store leftover cake in an airtight container in the refrigerator for up to 4 days.
Wrap individual slices tightly in plastic wrap and freeze for up to 2 months.
Thaw frozen slices overnight in the refrigerator before serving.
Reheat a slice in the microwave for 10-15 seconds to soften the crumb topping and cake.
Frozen blackberries work well – do not thaw them first, just toss them in flour while still frozen.
