15-Minute Cream Cheese-Swirled Mixed Berry Cake
Tender, spiced sheet cake studded with frozen berries and topped with swirled cream cheese. Cinnamon and nutmeg warm the crumb while a dollop of sweetened cream cheese creates pockets of richness. Baked in an 8-inch square pan, this simple cake requires minimal mixing to keep the texture tender and light.

Instructions
- 1
Preheat oven to 350F. Line an 8-inch square pan with aluminum foil and spray with cooking spray.
- 2
In a large bowl, whisk together flour, sugar, baking powder, cinnamon, nutmeg, and salt.
- 3
In a separate small bowl, whisk together egg, buttermilk, sour cream, oil, and vanilla extract.
- 4
Add wet mixture to dry mixture and fold gently with a spatula until just combined. Do not overmix; lumps are expected.
- 5
In a small bowl, toss fruit with flour to prevent sinking during baking.
- 6
Gently fold fruit into batter.
- 7
Pour batter into prepared pan.
- 8
In a small bowl, whisk together softened cream cheese with sugar until smooth.
- 9
Dollop cream cheese mixture over batter surface. Using a toothpick, gently swirl to create patches rather than thin streaks.
- 10
Bake until center is slightly domed and set, golden and rosy in color, and a toothpick inserted in the center comes out clean or with a few moist crumbs. If cake begins to brown too quickly, tent with foil.

Optionally dust with confectioners' sugar or glaze as desired.
Tips
Toss frozen berries with flour to prevent them from sinking to the bottom during baking.
Do not overmix the batter after combining wet and dry ingredients; lumps are expected and keep the cake tender.
Watch the cake, not the clock; baking time varies significantly based on whether berries are fresh or frozen.
If cake is browning too quickly before the center sets, tent with foil starting around 45 minutes.
Swirl the cream cheese gently with a toothpick to create visible patches rather than thin streaks throughout.
Allow cake to cool at least 30 minutes before slicing to ensure the crumb sets properly.
Good to Know
Cover and store at room temperature up to 2 days, or refrigerate up to 4 days.
Prepare batter and fruit toss up to 2 hours ahead; fold fruit into batter just before baking. Cream cheese mixture can be prepared up to 4 hours ahead and refrigerated.
Serve at room temperature or slightly warm. Pair with coffee, tea, or vanilla ice cream. Dust with confectioners' sugar or top with glaze if desired.
Common Mistakes
Overmix the batter after combining wet and dry to avoid a tough, dense crumb.
Skip tossing berries with flour to avoid them sinking to the bottom.
Add cold cream cheese without softening and whisking to avoid lumpy swirls.
Rely on time rather than visual cues to avoid underbaking or overbaking due to berry temperature variation.
