Ingredients
Butter Crumble
3/4 cup (90 g) all-purpose flour
1/3 cup (67 g) granulated sugar
Pinch fine salt
4 tablespoons (57 g) cold unsalted butter, cubed
Lemon Blueberry Cake
2 cups (240 g) all-purpose flour, spooned and leveled
1 1/2 teaspoons baking powder
1/4 teaspoon baking soda
1/2 teaspoon fine salt
8 tablespoons (113 g) unsalted butter, softened
3/4 cup (150 g) granulated sugar
1 tablespoon finely grated lemon zest, yellow part only
2 large eggs, room temperature
1/2 cup (120 g) full-fat sour cream, room temperature
2 tablespoons (30 ml) whole milk
2 tablespoons (30 ml) fresh lemon juice
1 teaspoon alcohol-free vanilla flavoring
1 1/2 cups (225 g) fresh blueberries, rinsed and thoroughly dried
Cream Cheese Pockets
8 ounces (226 g) full-fat block cream cheese, softened
1/4 cup (50 g) granulated sugar
1 large egg, room temperature
2 teaspoons (6 g) cornstarch
1/2 teaspoon alcohol-free vanilla flavoring
Instructions
- Heat the oven to 350°F (175°C), conventional setting, with a rack in the center. Grease a deep 9 × 9-inch baking dish, at least 2 inches deep. Measure the inside, not the handles. Start with room-temperature dairy and eggs, allowing this within the preparation window and keeping perishable ingredients out no longer than food-safety limits.
- Make the crumble: stir its flour, sugar, and salt in a bowl. Cut or rub in the cold butter until irregular pea- to marble-sized clumps form. Squeeze loose crumbs gently into clusters. Refrigerate while preparing the cake and filling.
- Make the cream cheese filling: beat the softened block cream cheese and 1/4 cup sugar until smooth. Mix in the egg, cornstarch, and 1/2 teaspoon alcohol-free vanilla on low just until combined. Set aside briefly while mixing the batter.
- Whisk the cake flour, baking powder, baking soda, and salt in a separate bowl. Rub the lemon zest into the cake sugar with clean fingertips. Beat the softened butter with the lemon sugar until lighter and fluffy, about 2 to 3 minutes. Beat in the 2 eggs one at a time, scraping the bowl. Mix in the sour cream, milk, lemon juice, and 1 teaspoon alcohol-free vanilla; slight curdling at this stage is normal.
- Add the dry ingredients in 2 additions, mixing on low just until no dry streaks remain. Fold in the dried blueberries with a flexible spatula. Spread all the batter evenly in the greased dish, including the corners.
- Spoon the cream cheese mixture over the batter in 12 roughly equal dollops, about 1 1/2 to 2 tablespoons each. Gently nestle them slightly into the batter without stirring them into a uniform layer. Scatter the cold crumble over the surface, leaving a few cream cheese patches visible. Do not pack the crumble down.
- Bake for about 60 to 75 minutes in a ceramic dish, beginning checks around 55 minutes; 65 minutes is the planning estimate. The crumble should be golden, the cake center should spring back lightly, and a skewer inserted into cake batter near the center, avoiding berries and cream cheese pockets, should show no wet batter. The cream cheese pockets should be set, not liquid. If using a thermometer, the egg-containing filling should reach at least 160°F (71°C); that temperature alone does not prove the surrounding cake is fully baked. Tent loosely with foil if the topping browns before the center is ready.
- Cool in the dish on a wire rack for about 60 minutes before serving slightly warm or cutting neater pieces. Keep the ceramic dish away from cold or wet surfaces to avoid thermal shock. Cut into 12 portions and lift with a small spatula. Refrigerate remaining portions promptly in shallow containers, within 2 hours of leaving the oven (within 1 hour if the room is above 90°F/32°C). Do not wait for the entire cake to become completely cold on the counter.
Notes
Timing: 30 minutes preparation + an estimated 65 minutes baking + 60 minutes cooling = 155 minutes (2 hours 35 minutes) ready to serve. With the stated 60–75-minute bake range, allow about 2 hours 30 minutes to 2 hours 45 minutes. Ingredient softening should overlap preparation; add time if needed. The crumble chills while you work. These are planning estimates, not measured kitchen-test times.
Pan: Use a 9-inch square interior at least 2 inches deep. A dish advertised as 9 inches may include the handles or rim; check its internal dimensions. Do not force this quantity into a shallow 8-inch dish. Metal pans may finish sooner; follow doneness rather than adding a fixed time.
Blueberries: Fresh, dry berries give the most predictable result. Frozen berries can be folded in straight from the freezer; do not thaw. Expect some color bleeding and potentially extra baking time. Do not add a second berry layer.
Cream cheese: Use full-fat block cream cheese, not whipped or spreadable cream cheese. Keep the mixture in separate dollops for visible pockets.
Storage: Because of the egg-and-cream-cheese filling, refrigerate at 40°F (4°C) or below. Enjoy within 3 to 4 days as a conservative quality guideline. Freeze wrapped portions for up to 1 month for best quality and thaw in the refrigerator. The crumble may soften.
Make ahead: Bake the day before, cool safely, and refrigerate. Serve chilled or let individual servings lose their chill briefly within the same room-temperature limits.
