Ingredients
Scale
- 1 1/2 cups all-purpose flour (you can substitute with whole wheat pastry flour for a nuttier flavor)
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened (or use coconut oil for a dairy-free version)
- 3/4 cup granulated sugar (feel free to reduce to 1/2 cup if you prefer less sweetness)
- 2 large eggs, at room temperature
- 1 teaspoon vanilla extract
- 1/2 cup sour cream (or Greek yogurt for a tangier twist)
- 1 cup fresh blueberries (frozen can be used, but do not thaw to avoid excess moisture)
- For the cream cheese swirl:
- 8 ounces cream cheese, softened
- 1/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 1 large egg
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with parchment paper for easy removal—Mama Lou always said this was the secret to a perfect loaf.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- In a large bowl, beat the softened butter and sugar together until light and fluffy, about 3-4 minutes. This step is where the magic starts, and I remember Ouma sneaking tastes of the batter while I wasn’t looking.
- Add the eggs one at a time, beating well after each addition. Stir in vanilla extract.
- Mix in the sour cream until just combined. The batter will be thick and luscious.
- Gradually fold the dry ingredients into the wet mixture. Be gentle to keep the batter airy.
- Toss the blueberries in a tablespoon of flour (this helps prevent them from sinking) and gently fold them into the batter.
- In a separate bowl, beat together the cream cheese, sugar, vanilla extract, and egg until smooth and creamy.
- Pour half of the blueberry batter into the prepared loaf pan. Spoon half of the cream cheese mixture over the batter. Repeat layers with remaining batter and cream cheese mixture.
- Use a knife or skewer to gently swirl the cream cheese through the batter, creating beautiful marbled patterns. This step always reminds me of the delicate way Mama Lou would swirl colors into her cakes.
- Bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean (a few moist crumbs are okay but no wet batter).
- Allow the loaf to cool in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing. Patience here is key—slicing too soon will cause it to crumble, and you don’t want to miss a single perfect slice.
