Hey there, I’m Rolla!

Let me tell you about the first time I made this Double Chocolate Coca Cola Cake. My oldest was turning eight and I wanted something special but not too fancy. I found an old recipe card at my neighbor’s house and thought, “Coca Cola in a cake? That sounds crazy.” But I tried it anyway.

Oh my goodness — the whole kitchen smelled like the best chocolate shop in town. When I pulled it out of the oven, my kids came running. That glossy frosting poured over the warm cake and sank in just a little… they were fighting over who got the corner pieces with extra frosting.

Fifteen years later, I’ve probably baked this Double Chocolate Coca Cola Cake more than fifty times. It’s been to birthday parties, church suppers, family reunions, and even a few “I had a rough day” evenings. My husband still says it’s his favorite cake ever, and my grandbabies call it “the special black cake.”

There’s just something about that secret Coca Cola touch that makes the cake unbelievably tender and chocolatey. It’s not too sweet, stays moist for days, and the frosting? Pure heaven. Even if you’re not a confident baker, this one is forgiving and turns out beautiful every single time. I promise you’ll get requests for the recipe — I always do!

This is my go-to when I need a cake that makes everyone happy.

Ingredients

Cake:

• 1 cup Coca Cola (real thing, not diet — trust me on this)
• ½ cup oil
• 1 stick (½ cup) butter
• 3 tablespoons cocoa powder
• 2 cups sugar
• 2 cups all-purpose flour
• ½ teaspoon salt
• 2 eggs
• ½ cup buttermilk
• 1 teaspoon baking soda
• 1 teaspoon vanilla

Frosting:

• 1 stick (½ cup) butter
• 3 tablespoons cocoa
• 6 tablespoons milk or cream
• 1 teaspoon vanilla extract
• 3¾ cups powdered sugar

I always use real butter. It just tastes better.

Instructions

1. Preheat oven to 350°F and grease a 13×9 pan really well.
2. In a saucepan, mix Coca Cola, oil, butter, and cocoa. Bring to a boil while you stir. The smell is amazing already.
3. In a big bowl, stir together sugar, flour, and salt.
4. Pour that hot cola mixture over the dry ingredients and beat until smooth.
5. Add eggs, buttermilk, baking soda, and vanilla. Mix well — the batter will be thin, but that’s exactly what you want.
6. Pour into your pan and bake 20-25 minutes until the center springs back when touched.
7. Let it cool about 10 minutes while you make the frosting.

For the frosting: Melt butter, cocoa, and milk in a saucepan. Take off heat and beat in vanilla and powdered sugar until nice and smooth. Spread over the warm cake — it gets all fudgy and delicious.

My Best Cooking Tips & Kitchen Secrets

I always let my eggs and buttermilk sit out for a bit so they mix better. Don’t overbake — 22 minutes is usually perfect in my oven. Make the frosting while the cake bakes so you can spread it while the cake is still warm. That’s the secret to that beautiful fudgy top. If the frosting gets too thick, splash in a tiny bit more milk.

Fun Variations & Substitutions

• Use Cherry Coke for a fun cherry-chocolate twist
• Stir in ½ cup chocolate chips for extra pockets of chocolate
• Make cupcakes instead (bake about 18 minutes)
• Add a pinch of cinnamon for a warm Mexican chocolate vibe

How to Store & Make Ahead

This cake stays perfect on the counter for 3-4 days in a covered container. It also keeps a week in the fridge. Freezes great — I wrap slices individually and pull one out whenever I need a treat. Tastes almost as good as fresh after thawing.

Perfect Serving Ideas

Slightly warm with vanilla ice cream is my family’s favorite. Cold with coffee in the morning is pretty wonderful too. Great cut into small squares for parties or with fresh berries on the side.

Frequently Asked Questions

Can I use diet Coke? I really don’t recommend it — the real sugar is part of what makes it so good.

Does it taste like soda? Not at all. Just deep, rich chocolate flavor.

Can I make it ahead? Yes! Bake the cake the day before and frost fresh if you want.

My frosting is too thick? Add milk one teaspoon at a time until it’s spreadable.

Can I use a round pan? Sure, but watch the baking time.

Is buttermilk necessary? It makes it extra tender, but milk + lemon juice works fine.

How do I store leftovers? Covered at room temp for a few days or fridge for longer.

Can I double it? Absolutely — perfect for big crowds.
