There’s something about a cornmeal cake that feels like it belongs on a porch table, not a fancy plate.
I started making this blackberry cornmeal cake after a summer trip to a farm stand that sold berries by the flat. I had way too many and needed something besides jam.
The cornmeal gives the crumb a little grit, almost like a good muffin top. Buttermilk keeps it from tasting dry, and a scatter of sugar on top turns into a thin, crackly crust as it bakes, much like the crust on a buttermilk sugar cake.
This isn’t a fussy cake. One bowl, no mixer needed, and it comes together faster than the oven takes to preheat.
Why You’ll Love This Recipe
- One bowl, no mixer, ready in about an hour
- Cornmeal adds crunch without extra fuss
- Buttermilk keeps the crumb moist for days
- Fresh or frozen blackberries both work well
Ingredient Notes
- Cornmeal: Medium grind gives the best texture, gritty but not sandy. Fine cornmeal works too, the crumb will just be a bit softer.
- Buttermilk: Adds tang and keeps the crumb tender. No buttermilk? Stir 2 tsp lemon juice into 3/4 cup milk and let it sit 5 minutes.
- Blackberries: Fresh or frozen both work, don’t thaw frozen ones first. Toss them in flour before folding in so they don’t all sink.
- Lemon zest: Brightens the batter and cuts the sweetness. Orange zest works as a milder swap.
- Butter: Use unsalted and let it soften fully at room temp so it creams smoothly with the sugar.
Blackberry Cornmeal Cake with Golden Sugared Crust
Ingredients
Method
- Heat oven to 350F / 175C. Grease a 9-inch round cake pan and line the bottom with parchment.
- Whisk the flour, cornmeal, baking powder, baking soda, and salt together in a bowl. Set aside.
- In a large bowl, cream the butter and 3/4 cup sugar with a spoon or hand mixer for 2 minutes until pale.
- Beat in the eggs one at a time, then stir in the buttermilk and lemon zest until smooth (the mix may look slightly curdled, that's fine).
- Fold the dry ingredients into the wet just until no flour streaks remain. Don't overmix.
- Toss the blackberries with 1 tbsp flour, then fold gently into the batter, saving a handful for the top.
- Pour the batter into the prepared pan. Scatter the reserved blackberries and 2 tbsp sugar over the top.
- Bake 40 to 45 minutes, until a toothpick in the center comes out clean with a few moist crumbs and the edges are golden and pulling from the pan.
- Cool in the pan 10 minutes, run a knife around the edge, then transfer to a rack to cool before slicing.
Notes
- Toss blackberries in flour to stop them sinking during baking.
- Use room-temp butter and eggs for even mixing.
- Don't overmix once flour goes in, or the crumb turns tough.
- Swap lemon zest for orange zest for a milder citrus note.
Tips for Success
- Toss blackberries in a tablespoon of flour before folding them in, this keeps them suspended instead of sinking to the bottom.
- Use room temperature butter and eggs so the batter mixes smoothly without curdling or leaving lumps of cold butter.
- Stop mixing as soon as the flour disappears, overworked batter turns the crumb dense and rubbery instead of tender.
- Check the cake at 38 minutes since oven temps vary, pull it once a toothpick comes out with a few moist crumbs.
- Let the cake cool at least 10 minutes in the pan before running a knife around the edge to release it cleanly.
Variations
- Swap blackberries for blueberries or raspberries when berries are out of season, keep the same 2 cup amount.
- Add 1/4 teaspoon ground cardamom or cinnamon to the dry mix for a warmer, spiced version of the cake.
- Bake in a cast iron skillet instead of a cake pan for crisper edges and a slightly smoky crust.
Storage and Reheating
Blackberry cornmeal cake keeps well at room temperature for up to 2 days, covered loosely so the sugared top stays crisp.
For longer storage, move it to the fridge in an airtight container for up to 5 days. The crumb stays moist thanks to the buttermilk, though the top loses some crunch.
To freeze, wrap individual slices in plastic and store up to 3 months. Reheat a slice in a 300F / 150C oven for 8 to 10 minutes, or 20 seconds in the microwave, straight from frozen or thawed.
Serving Suggestions
Serve blackberry cornmeal cake warm with a scoop of vanilla ice cream or a spoonful of softly whipped cream, both play well against the tart berries and gritty crumb.
A dusting of powdered sugar or a thin drizzle of honey over each slice adds a little extra sweetness without covering up the cornmeal flavor.
It also works plain, sliced thick, alongside a cup of coffee for breakfast, in the same easygoing spirit as a vintage cherry dump cake for an afternoon snack.
FAQ
Why did my blackberries sink to the bottom of the cornmeal cake?
Blackberries sink when they’re not coated before going into the batter or when the batter itself is too thin. Toss the berries in a tablespoon of flour before folding them in, this gives the batter something to grip. A thicker batter, like the one here with just 3/4 cup buttermilk, also helps hold the fruit in place.
Can I use frozen blackberries instead of fresh in this cake?
Yes, frozen blackberries work, just don’t thaw them first. Adding them frozen means less bleeding into the batter and less sinking, though the bake may take an extra 3 to 5 minutes. Toss them in flour the same way you would fresh berries before folding in.
How do I know when the cornmeal cake is done baking?
The cake is done after 40 to 45 minutes at 350F / 175C, when a toothpick inserted in the center comes out clean with a few moist crumbs and the edges have pulled slightly away from the pan, turning golden brown. The center should also spring back lightly when pressed.
Can I make blackberry cornmeal cake a day ahead?
Yes, and it actually tastes better the next day once the crumb settles and the flavors even out. Store it covered at room temperature for up to 2 days, or in the fridge for up to 5. Bring it to room temp, or warm a slice briefly, before serving.
What goes well with blackberry cornmeal cake for dessert?
Whipped cream or vanilla ice cream work well against the tart berries and gritty crumb, cutting the tang and adding richness. A light drizzle of honey or a dusting of powdered sugar also does the job without masking the cornmeal flavor. Coffee is a good match too, for breakfast or an afternoon slice.
Is blackberry cornmeal cake gluten free?
Not as written, since this recipe uses all-purpose flour alongside the cornmeal. Swap in a 1:1 gluten-free flour blend to make it gluten free, the cornmeal itself is naturally gluten free. Double check your baking powder label too, since some brands include wheat starch as a filler.
