Bake With the Seasons · September

Some cakes are really desserts. Others quietly make the case that cake belongs beside your morning coffee.

This blackberry cornmeal cake happily does both.

Fresh blackberries sink into a tender, buttery batter while a little cornmeal gives the cake golden edges and a subtle texture that makes every bite more interesting. The berries become soft and jammy in the oven, leaving streaks of deep purple through the warm yellow crumb.

It is rustic, fruit-forward, and wonderfully unfussy—the kind of seasonal cake that needs no frosting at all.

Ingredients

• 1 cup all-purpose flour
• 1/2 cup fine or medium-ground yellow cornmeal
• 1 1/2 teaspoons baking powder
• 1/4 teaspoon baking soda
• 1/2 teaspoon fine salt
• 1/2 cup unsalted butter, softened
• 3/4 cup granulated sugar, plus a little extra for the top
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup plain Greek yogurt or sour cream
• 2 tablespoons milk
• 1 teaspoon finely grated lemon zest, optional but lovely
• 1 1/2 cups fresh blackberries

How to Make Blackberry Cornmeal Cake

1. Prepare the Pan

Preheat the oven to 350°F (175°C). Grease an 8- or 9-inch round cake pan and line the bottom with parchment paper.

2. Mix the Dry Ingredients

Whisk together the flour, cornmeal, baking powder, baking soda, and salt. Set aside.

3. Cream the Butter and Sugar

In a large bowl, beat the softened butter and sugar until lighter and creamy. A hand mixer makes this quick, although a sturdy whisk and a little determination will also get you there.

4. Add the Eggs and Vanilla

Beat in the eggs one at a time, followed by the vanilla and optional lemon zest.

5. Finish the Batter

Stir together the Greek yogurt and milk. Add the dry ingredients to the butter mixture in two additions, alternating with the yogurt mixture. Fold just until combined.

The batter will be fairly thick. That helps suspend the berries rather than sending every blackberry straight to the bottom of the pan.

6. Add the Blackberries

Gently fold about 1 cup of the blackberries into the batter. Spread the batter evenly into the prepared pan, then scatter the remaining berries over the top.

Sprinkle the surface with a teaspoon or two of granulated sugar for a delicate crisp finish.

7. Bake

Bake for approximately 35–45 minutes, until the cake is golden and a toothpick inserted into an area without a blackberry comes out with a few moist crumbs.

Let the cake cool in the pan for about 15 minutes before carefully removing it.

Why Put Cornmeal in a Cake?

Cornmeal changes the texture without turning the cake into cornbread.

Used alongside regular flour, it adds a faintly crisp quality around the edges and a subtle, pleasantly rustic texture throughout the crumb. Its mild sweetness also works especially well with berries, stone fruit, citrus, and honey.

What Kind of Cornmeal Should I Use?

Fine- or medium-ground yellow cornmeal works best here. Very coarse cornmeal can make the finished cake noticeably gritty, while corn flour is much finer and behaves differently.

Ordinary yellow cornmeal from the baking aisle is perfectly suitable—there is no need for anything fancy.

Can I Use Frozen Blackberries?

Yes. Frozen blackberries can be used when fresh berries aren’t available.

Add them directly from frozen rather than thawing them first. Thawed berries release a great deal of juice and can turn the batter purple before it ever reaches the oven. A cake made with frozen berries may also need a few additional minutes of baking time.

Can I Use Other Berries?

Absolutely. This batter is a useful one to remember as the seasons change.

• Blueberries: an especially easy substitution.
• Raspberries: softer and more tart, but delicious.
• Strawberries: chop larger berries before folding them into the batter.
• Mixed berries: use whatever combination needs to be eaten.
• Blackberry and peach: replace part of the berries with small pieces of ripe peach.

Blackberry, Lemon, or Honey?

Blackberries can handle a little company.

Lemon zest makes their flavor brighter without making the cake taste strongly of lemon. Honey drizzled over a warm slice pushes it in a softer, more autumnal direction. A little vanilla ice cream turns the whole thing into dessert.

You can even scatter sliced almonds over the top before baking if you want a little additional crunch.

What to Serve With Blackberry Cornmeal Cake

For breakfast or an afternoon snack, serve a slice as it is with coffee or tea.

For dessert, try it slightly warm with vanilla ice cream, whipped cream, Greek yogurt, mascarpone, fresh berries, or a thin drizzle of honey.

Storage

Keep the completely cooled cake covered at room temperature for about one day. For longer storage, refrigerate it in an airtight container for approximately 3–4 days.

Bring refrigerated slices toward room temperature before serving or warm them gently for a few seconds.

Baking With September Blackberries

Blackberries belong to that delicious overlap between seasons. They can still taste unmistakably like summer when eaten straight from the basket, yet bake them into a golden cake and suddenly they feel perfectly at home beside the first pears, apples, and cooler evenings of early autumn.

That overlap is exactly what our Bake With the Seasons collection is meant to celebrate: using fruit while it is abundant and letting the calendar slowly change what comes out of the oven.

More September Baking

• Fresh Fig & Honey Cake — tender yogurt cake with ripe figs, almonds, and honey.
• Plum Crumble Bars — juicy fresh plums tucked between a buttery oat crust and crumble.
• Pear & Almond Galette — seasonal pears over almond filling in an easy rustic pastry.
• Apple Cider Donut Cake — cinnamon-sugar autumn comfort without frying a single donut.

Save a few of the prettiest berries for the top. Watching them collapse into little purple pools as the cake rises around them might be half the pleasure of making it.
