Prepare the Blackberry Layer
1
|
In a saucepan, combine blackberries, sugar, and lemon juice. Cook over medium heat until berries soften and release their juices.
2
|
In a small bowl, whisk cornstarch with water, then stir into the pan. Cook 1 to 2 minutes until thick and jammy.
3
|
When you drag a spoon through the mixture, it should leave a clear streak that slowly fills back in.
4
|
Set aside to cool (or refrigerate).
Brown the Butter
1
|
In a light-colored saucepan, melt butter over medium heat. Cook until foamy, golden, and nutty, about 5 to 7 minutes.
2
|
Pour into a heatproof bowl and cool until warm but not hot.
Make the Streusel
1
|
In a bowl, mix brown sugar, granulated sugar, flour, salt, and lemon zest.
2
|
Add the portion of browned butter and vanilla. Mix until crumbly.
3
|
Use your hands to form both large and small clumps.
4
|
Refrigerate while preparing the batter.
Make the Cake Batter
1
|
Preheat oven to 350°F (175°C). Line a 9-inch round pan with parchment.
2
|
Whisk browned butter with granulated and brown sugar.
3
|
Add eggs, yolk, vanilla, sour cream, and milk. Whisk until smooth.
4
|
In a separate bowl, whisk flour, baking powder, baking soda, and salt.
5
|
Fold dry ingredients into wet until just combined. Do not overmix.
Assemble
1
|
Spread about 3/4 of the batter evenly in the pan.
2
|
Spoon blackberry filling over top and gently swirl.
3
|
Carefully spread remaining batter over the jam. Some mixing is fine.
4
|
Sprinkle streusel evenly over the top.
Bake
1
|
Bake 40 to 45 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.
2
|
Cool in the pan for 30 minutes, then transfer to a wire rack to cool completely.
3
|
Dust with powdered sugar before serving.

Tips & Tricks (5)
- Brown Your Butter Slowly 🧈Cook butter over medium heat for 8-10 minutes, swirling occasionally, until it turns deep golden with a nutty aroma—don't rush this step as it's the signature flavor of your streusel.
- Macerate Blackberries First 🫐Toss blackberries with cornstarch and lemon juice 15 minutes before adding to the batter to release their juices and create a jammy filling without soggy cake.
- Keep Streusel Chunky 🤏Mix your brown butter streusel with a fork rather than a pastry cutter to create distinct, crunchy pieces that won't compact into a dense layer during baking.
- Room Temperature Eggs and Dairy 🥚Remove eggs, sour cream, and milk from the refrigerator 30 minutes before baking to ensure proper emulsification and a tender, plush crumb structure.
- Toothpick Test at 35 Minutes ⏱️Start checking doneness at 35 minutes with a toothpick in the cake (not through a berry)—it should come out with a few moist crumbs, preventing overbaking while ensuring full set.
