Yield
Serves 10 generous slices
Difficulty Level
Medium – approachable for home bakers ready to elevate their cake game
Ingredients
- 2 cups all-purpose flour, sifted
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1 1/2 tsp ground cinnamon
- 1/4 tsp ground nutmeg
- 1/4 tsp ground cloves
- 3/4 cup unsalted butter, softened
- 1 cup granulated sugar
- 1/2 cup packed light brown sugar
- 3 large eggs, room temperature
- 1 tsp pure vanilla extract
- 1 cup buttermilk, room temperature
- 1 cup fresh blackberries, gently rinsed and patted dry
- 1/2 cup high-quality blackberry jam
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line it with parchment paper for easy release.
- In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and the aromatic blend of cinnamon, nutmeg, and cloves.Set aside.
- In a large mixing bowl, cream the softened butter with granulated sugar and brown sugar until light and fluffy, about 3-4 minutes using an electric mixer on medium speed.
- Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next, then mix in the vanilla extract.
- Alternate adding the dry ingredients and buttermilk in three additions, starting and ending with the flour mixture. Mix gently to avoid overworking the batter, which keeps the crumb tender.
- Fold in the fresh blackberries carefully, distributing them evenly but taking care to not crush the berries and turn the batter purple.
- Spoon half of the batter into the prepared pan, then dollop the blackberry jam evenly over the batter. swirl the jam gently with a skewer or knife to create a marbled effect.
- Add the remaining batter on top, smoothing it gently without disturbing the jam swirl.
- Bake for 45-50 minutes or until a toothpick inserted near the center comes out clean or with just moist crumbs. The top should be golden brown with a slightly crisp crust.
- Cool in the pan for 15 minutes, then transfer to a wire rack to cool wholly before slicing. This resting period lets the flavors fully develop and the moisture redistribute.
Tips for Success
- Use room temperature ingredients-this helps the batter emulsify properly for that ultimate moist crumb.
- Choose fresh blackberries that are firm and ripe; under-ripe berries can lend bitterness, while over-ripe ones might dissolve too much.
- If you prefer a more subtle spice profile, reduce cinnamon to 1 tsp and omit the nutmeg.
- For an extra burst of blackberry flavor,lightly toss the berries in 1 tablespoon of flour before folding into the batter-this prevents sinking.
- You can prepare the batter a day in advance and refrigerate it overnight; just bring to room temperature and gently re-mix before baking.
