Ingredients

2 cups cornmeal
1 cup all-purpose flour
2 large eggs
1 cup mayonnaise
2 to 2.5 cups buttermilk
1/2 cup granulated sugar
3 tsps salt
1/2 cup vegetable oil (plus an additional 1/2 cup for the skillet)

Step-by-Step Instructions

Step 1: Heat the Skillet

Preheat your oven to 375°F (190°C). Place a cast-iron skillet containing 1/2 cup of vegetable oil onto the stove over medium-high heat to warm up while you prepare your batter.

Step 2: Mix the Batter

In a large mixing bowl, combine the cornmeal, all-purpose flour, eggs, mayonnaise, buttermilk, sugar, salt, and 1/2 cup of vegetable oil. Mix until well incorporated, ensuring the finished batter reaches a balanced texture that is neither too thin nor too thick.

Step 3: Pour and Sizzle

Carefully pour the batter into your hot skillet; it should sizzle a bit as it hits the hot oil. Smooth the surface of the poured batter out using a silicone spatula—notice how the oil will pool around the surface of the batter, which is exactly what you want to happen.

Step 4: Bake to Golden Perfection

Bake in the preheated oven until the crust is a gorgeous golden brown, which takes around 35 minutes. Let cool slightly before slicing and serving.

Expert Cooking Tips

Preheat Your Skillet Properly: Letting the cast iron and oil get hot on the stove before adding the batter is the secret to achieving that signature crispy, golden crust.
Embrace the Oil Pool: When smoothing the batter into the hot skillet, seeing oil pool around the top edges is part of the traditional method that ensures extra moisture and crunch.
Check the Consistency: Adjust your buttermilk amount between 2 to 2.5 cups to ensure the batter flows smoothly without becoming runny or dense.
Don’t Fear the Mayo: Mayonnaise provides the emulsified fat and moisture that guarantees a tender interior every single time.

Variations to Try

Savory Cheese Addition: Fold a cup of sharp cheddar cheese or diced jalapeños into the batter for a rich, spicy kick.
Bacon Fat Swap: Substitute bacon grease for a portion of the vegetable oil in the cast-iron skillet for an even deeper, smoky Southern flavor.
Honey Drizzle: Serve warm wedges with a drizzle of honey or hot honey for those who love a sweet-and-savory balance.

What to Serve With Aunt’s Cornbread

Comfort Sides: Serve alongside traditional fried cabbage, roasted potatoes, and sliced smoked sausage.
Soups and Stews: Perfect for dipping into hearty pinto beans, chili, or traditional vegetable soup.
Southern Spreads: Slather warm slices with real butter and a touch of fruit preserves.

Frequently Asked Questions

Why put mayonnaise in cornbread?

Mayonnaise is made of oil and eggs, which add incredible moisture, structure, and tenderness to baked goods, ensuring the cornbread never turns out dry.

Do I have to use a cast-iron skillet?

While a cast-iron skillet provides the best heat retention for a crispy outer crust, you can use a heavy baking dish if cast iron isn’t available.

Why is oil pooling on top of my batter when I pour it?

That is part of the traditional technique! The hot oil in the skillet rises slightly around the edges of the batter as you smooth it out, helping fry the outer edges to perfection.

Can I reduce the sugar?

Yes, you can adjust the sugar down if you prefer a more traditional savory cornbread, though 1/2 cup provides a wonderful balance of flavor.
