Steps
Before you start
- Preheat oven to 350°F (175°C)
- Grease and line a 9-inch (23 cm) round cake pan with parchment paper
- Bring eggs and milk to room temperature
- Gently toss blackberries with 1 tablespoon of the measured flour to prevent sinking
Cream butter and sugar
- In a large mixing bowl, whisk together the softened butter and granulated sugar until pale and fluffy, about 2–3 minutes of vigorous whisking.
- The mixture should be noticeably lighter in color and texture.

Ready when: Mixture is pale, fluffy, and takes up more volume
Tip: Room-temperature butter incorporates air more easily than cold butter, giving you a lighter crumb.
Add eggs and aromatics
- Add the eggs one at a time, whisking well after each addition so each is fully incorporated before adding the next.
- Then whisk in the lemon zest, lemon juice, and vanilla extract.
- The batter may look slightly curdled—this is fine.

Ready when: All eggs are incorporated; lemon juice and zest are distributed throughout
Tip: Whisking each egg thoroughly prevents overbeating the whole mixture, which can make the cake tough.
Combine dry ingredients
- In a medium bowl, whisk together the flour, cornmeal, baking powder, and salt until evenly distributed.
- This ensures the leavening is spread uniformly throughout the cake.

Ready when: Flour, cornmeal, baking powder, and salt show no visible lumps or streaks
Tip: Whisking the dry ingredients separately prevents lumpy pockets of baking powder in the finished cake.
Alternate wet and dry
- Pour about one-third of the dry mixture into the wet ingredients and whisk until just combined.
- Pour in half the milk and whisk until just combined.
- Repeat with another third of the dry mixture, the remaining milk, and finish with the last third of the dry mixture.
- Stop as soon as you don't see dry streaks—do not overmix.

Ready when: Batter is smooth and no dry flour streaks are visible
Tip: Alternating wet and dry keeps the batter tender. Overmixing once the flour is added will overdevelop gluten and make the cake dense and tough.
Fold in blackberries
- Using a wooden spoon or rubber spatula, gently fold the floured blackberries into the batter with a few broad strokes.
- Be gentle so the berries don't break apart and release their juice too much (which can create dark streaks).

Ready when: Blackberries are evenly distributed throughout the batter
Tip: Tossing the blackberries in flour before folding them in helps them stay suspended and prevents them from sinking to the bottom of the pan.
Pour into prepared pan
- Scrape the batter into the prepared 9-inch cake pan and smooth the top with a spatula.
- The batter should fill the pan about three-quarters full.

Ready when: Batter is level in the pan with a smooth or slightly textured top
Tip: If you see bare spots of pan, tap the bottom of the pan once or twice on the counter to settle the batter; don't stir or it will deflate.
Bake until goldenOven 350°F / 175°C
- Place the pan in a preheated 350°F (175°C) oven on the middle rack.
- Bake for 38–42 minutes, until the top is deep golden brown and a wooden pick inserted in the center comes out with a few moist crumbs (not wet batter, but not completely dry).

Ready when: Top is deep golden brown; a wooden pick inserted in the center comes out with just a few moist crumbs
Tip: All ovens bake differently. Start checking at 35 minutes; overbaking will dry out the cake, but a few moist crumbs are fine and actually better than dry.
Cool in pan then turn out
- Remove the cake from the oven and let it cool in the pan for 15 minutes.
- This allows the cake to firm up enough to handle.
- Then turn it out onto a cooling rack and cool completely before dusting with powdered sugar, if desired.

Ready when: Cake is completely cool to the touch and no longer steaming
Tip: Waiting 15 minutes in the pan prevents the warm, delicate cake from breaking when you turn it out. If it sticks, gently run a small knife around the edge first.
Good to know
Tips
- Bring eggs and milk to room temperature before starting. Cold ingredients incorporate poorly and can result in a dense, uneven crumb.
- Do not open the oven door in the first 30 minutes; the cake needs uninterrupted heat to rise properly.
- A quick dust of powdered sugar is optional but lovely. Wait until just before serving so it doesn't dissolve from the cake's residual moisture.
- This cake is best served still slightly warm or at room temperature the same day it is baked. After that, warm slices briefly in the oven for the best texture and flavor.
Make ahead
The cake can be baked up to 2 days ahead. Store it covered at room temperature or wrap it and refrigerate. Dust with powdered sugar just before serving so it doesn't dissolve from moisture.
Storage & reheating
Room temperature (covered): up to 2 days. Refrigerator (wrapped or in an airtight container): up to 4 days. Freezer (wrapped tightly in plastic wrap and foil): up to 3 months. To reheat, wrap loosely in foil and warm in a 300°F (150°C) oven for about 15 minutes until just warmed through. Do not microwave, as it will make the cake rubbery.
Substitutions
- fresh blackberries → fresh blueberries or raspberries (or a mix). Use the same weight. These softer berries will break more easily when folded, but the flavor is equally delicious. Frozen berries (thawed and drained) also work; use straight from frozen without thawing if you prefer, but add 2–3 minutes to the bake time.
- whole milk, at room temperature → buttermilk or Greek yogurt thinned with water (1:1 ratio). These add a subtle tang and create a slightly more tender crumb. If using buttermilk, reduce baking powder to 1 teaspoon and add 0.5 teaspoon baking soda to avoid a soapy taste.
- polenta or cornmeal (fine or medium grind) → all-purpose flour (use 0.5 cup / 60 g instead). The cake will be slightly less textured and nuttiness will be lost, but it will still be tender and delicious. The structure remains solid.
- fresh lemon juice → fresh orange juice or the zest and juice of a lime. Orange adds warmth; lime adds a brighter note. Use the same amount of juice and grate the zest if switching, then reduce or skip the lemon zest accordingly to avoid competing flavors.
