This recipe uses pantry staples with a few thoughtful additions that elevate the final result.

Coffee Cake

1 stick (8 tablespoons) salted butter, at room temperature – Provides richness and structure
1/2 cup + 1 tablespoon granulated sugar – Sweetens without overpowering
1 tablespoon lemon zest – Adds freshness and balance
1/2 cup sour cream – Creates a moist, tender crumb
1 tablespoon vanilla extract – Adds warmth and depth
3 eggs, at room temperature – Help emulsify and lift the batter
1 cup + 1 tablespoon all-purpose flour
3/4 cup almond flour (or 1/2 cup all-purpose flour) – Adds softness and subtle nuttiness
2 teaspoons baking powder – Leavening for a light texture
1/2 teaspoon kosher salt – Balances sweetness
1 cup fresh or frozen blueberries – Juicy bursts of flavor
3 tablespoons blueberry jam – Intensifies blueberry notes

Streusel

1/2 cup brown sugar
2 tablespoons flour
2 tablespoons butter
1 teaspoon cinnamon

Honey Lemon Glaze

2/3 cup powdered sugar
3 tablespoons lemon juice
1 teaspoon honey

Let’s Get Started

– Begin by preheating your oven to 350°F (175°C). Grease and line an 8-inch square or round baking pan with parchment paper, leaving a bit of overhang for easy removal.

– In a large mixing bowl, cream the room-temperature butter and granulated sugar until light and fluffy, about 2–3 minutes. Add the lemon zest and mix briefly to release its aroma. Stir in the sour cream and vanilla extract until fully combined.

– Add the eggs one at a time, mixing well after each addition. The batter should look smooth and creamy at this stage.

– In a separate bowl, whisk together the all-purpose flour, almond flour, baking powder, and kosher salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Avoid overmixing to keep the cake tender.

– Gently fold in the blueberries. If using frozen blueberries, add them straight from the freezer to prevent excess bleeding. Spoon about half of the batter into the prepared pan, smoothing the top. Drop small spoonfuls of blueberry jam over the batter and gently swirl with a knife. Add the remaining batter on top and smooth again.

– To make the streusel, combine brown sugar, flour, cinnamon, and butter in a small bowl. Use your fingers to rub the mixture together until crumbly. Sprinkle evenly over the batter.

– Bake for 45–55 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Let the cake cool in the pan for at least 20 minutes.

– While the cake cools, whisk together powdered sugar, lemon juice, and honey to form a smooth glaze. Drizzle over the cooled cake before slicing.

Servings and Pairing

This coffee cake serves 8–10 slices, depending on how generously you cut it. It’s filling enough to enjoy on its own, but pairing it thoughtfully can elevate the experience.

Serve with:

Freshly brewed coffee or espresso
Hot tea, especially black or herbal blends
Fresh berries on the side
Lightly sweetened yogurt

It also works beautifully as part of a brunch spread alongside savory dishes.

Variations

This recipe is easy to customize. Swap blueberries for raspberries, blackberries, or a mix of berries. Orange zest can replace lemon for a softer citrus note.

For a nut-free version, use all-purpose flour instead of almond flour. Add chopped nuts like pecans or walnuts to the streusel for extra crunch. If you prefer a less sweet finish, skip the glaze and serve the cake plain or lightly dusted with powdered sugar.
