Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 60 minutes
• Total Time: 1 hour 20 minutes
• Servings: 12
• Yield: 1 sheet cake
• Dietary Type: Vegetarian

Ingredients

• 6 ounces unsalted butter, room temperature
• 1 1/2 cups all-purpose flour
• 3/4 cup fine yellow cornmeal
• 1 1/2 teaspoons baking powder
• 3/4 teaspoon coarse salt
• 1 1/2 cups sugar
• 3 large eggs
• 1 1/2 teaspoons vanilla extract
• 3/4 cup buttermilk
• 18 ounces berries (use mix or any one of blueberries, raspberries, blackberries)
• 2 tablespoons sugar
• Garnish: Fresh berries and sweetened whipped cream (optional)

Equipment Needed

• 9×13 inch baking pan
• Parchment paper
• Mixing bowls
• Electric mixer (stand or hand-held)
• Whisk
• Rubber spatula
• Wire rack
• Toothpick

Instructions

1. Preheat your oven to 325°F (160°C). This lower temperature ensures the cake bakes evenly and prevents the berries from burning.
2. Prepare your baking pan. Butter a 9×13 inch baking pan thoroughly. Then, line the pan with parchment paper, leaving some paper overhanging the long sides. This makes it incredibly easy to lift the finished cake out of the pan. Finally, butter the parchment paper as well – this is additional butter and not from the 6 ounces listed as an ingredient.
3. In a medium bowl, whisk together the all-purpose flour, fine yellow cornmeal, baking powder, and coarse salt. Make sure everything is evenly distributed to ensure a consistent rise and flavor in your cake.
4. In a separate, large bowl, or in the bowl of your stand mixer, beat the softened butter and 1 1/2 cups sugar on medium-high speed until the mixture is pale and fluffy. This usually takes about 2 minutes. Creaming the butter and sugar properly is crucial for creating a light and tender cake crumb.
5. Beat in the eggs, one at a time, making sure each egg is fully incorporated before adding the next. Scrape down the sides and bottom of the bowl as needed to ensure everything is mixed evenly. Then, stir in the vanilla extract.
6. Gradually add the dry ingredients to the wet ingredients. Add the flour mixture in thirds, alternating with the buttermilk, beginning and ending with the flour. Beat until just combined. Be careful not to overmix the batter; overmixing can develop the gluten in the flour, resulting in a tough cake.
7. Spread the batter evenly into the prepared baking pan. Use a spatula to smooth the surface.
8. Evenly sprinkle the berries over the top of the batter. Then, sprinkle the 2 tablespoons of sugar evenly over the berries. The sugar will caramelize slightly during baking, adding a touch of sweetness and enhancing the berries’ natural flavors.
9. Bake in the preheated oven until the cake is golden brown and a toothpick inserted into the center comes out clean. This usually takes about 1 hour. Keep an eye on the cake towards the end of the baking time; ovens can vary, and you don’t want to overbake it.
10. Once baked, let the cake cool completely in the pan on a wire rack. This prevents the cake from sticking to the pan and allows it to firm up before cutting.
11. Using the overhanging parchment paper, carefully remove the cake from the pan. Cut into squares and serve. The cake is best served the same day, when it’s at its freshest. Garnish with fresh berries and sweetened whipped cream, if desired.

Expert Tips & Tricks

• Use room-temperature butter: Softened butter incorporates more easily with the sugar, creating a smoother, more even batter.
• Don’t overmix: Overmixing develops the gluten in the flour, leading to a tough cake. Mix until just combined.
• Berry placement matters: Gently press some of the berries slightly into the batter to prevent them from sinking to the bottom during baking.
• Adjust baking time: If the top of the cake is browning too quickly, tent it loosely with aluminum foil during the last 15-20 minutes of baking.
• Elevate the flavor: A squeeze of fresh lemon juice over the baked cake adds a bright, tangy contrast to the sweetness.

Serving & Storage Suggestions

This Cornmeal-Berry Sheet Cake is best served fresh, either warm or at room temperature. A dollop of sweetened whipped cream or a scoop of vanilla ice cream complements the flavors beautifully. Leftovers can be stored in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. To freeze, wrap individual slices tightly in plastic wrap and store in a freezer bag for up to 2 months. Thaw in the refrigerator before serving. To refresh the cake, you can warm it gently in a low oven (200°F/95°C) for a few minutes.

Variations & Substitutions

• Gluten-Free: Substitute the all-purpose flour with a gluten-free blend. Ensure the blend contains xanthan gum or add 1 teaspoon of xanthan gum to help bind the cake.
• Dairy-Free: Replace the buttermilk with a non-dairy alternative like almond milk or soy milk. You can also add 1 tablespoon of lemon juice or apple cider vinegar to the non-dairy milk to create a “buttermilk” substitute. Use a dairy-free butter substitute.
• Citrus Twist: Add the zest of one lemon or orange to the batter for a brighter flavor.
• Seasonal Berries: Feel free to adapt the berry mix based on what’s in season. Strawberries, blackberries, and even mixed stone fruits like peaches and plums would be delicious.
• Cornmeal Variation: For a coarser texture, try using a medium-grind cornmeal instead of fine.

FAQs (Frequently Asked Questions)

Q: Can I use frozen berries in this recipe?
A: Yes, you can use frozen berries. Do not thaw them before using. Toss them with a tablespoon of flour before adding them to the cake to help prevent them from bleeding into the batter too much.

Q: How do I prevent the cake from sticking to the pan, even with parchment paper?
A: Thoroughly buttering the pan before lining it with parchment paper, and then buttering the parchment paper itself, creates a double layer of protection against sticking.

Q: My cake is browning too quickly on top. What should I do?
A: If the top of the cake is browning too quickly, tent it loosely with aluminum foil during the last 15-20 minutes of baking. This will help to prevent it from burning.

Q: Can I make this cake ahead of time?
A: Yes, you can bake the cake a day in advance. Store it tightly wrapped at room temperature. Add the fresh berries and whipped cream just before serving.

Q: What’s the best way to tell if the cake is done?
A: The most reliable way is to insert a toothpick into the center of the cake. If it comes out clean, or with just a few moist crumbs attached, the cake is done.
