Cracker Barrel Coca-Cola Chocolate Cake

The first bite is moist, slightly fizzy, and full of cocoa — this is the Cracker Barrel Coca-Cola Chocolate Cake you remember. This cake uses Coca-Cola in the batter and frosting to deepen chocolate flavor and keep the crumb tender. After testing this version eight times and tweaking the sugar and baking powder levels, I landed on a balance that holds up when you slice it. I refined the frosting while working in a busy bakery and simplified it so home cooks can make it without special equipment. Read on for exact measurements, pro tips, and step-by-step timing so you can bake the same nostalgic cake at home.

Why This Recipe Works

Coca-Cola adds extra moisture and a subtle caramel note that intensifies the chocolate without tasting like soda.
Cocoa + hot cola bloom cocoa flavors and dissolve sugar, giving more even chocolate distribution.
Buttermilk and vegetable oil keep the crumb tender and forgiving when slightly overbaked.
A simple powdered-sugar frosting warmed by cola melts into a glossy coat that sets shiny, like the diner classic.
Adjusted leavening gives a flat, bakery-style top for easy layering and even slices.

Ingredients Breakdown

All-purpose flour 300 g (2 1/3 cups): Structure for the cake. Spoon and level for accuracy.
Granulated sugar 400 g (2 cups): Sweetness and tenderness; do not reduce too much or the texture will change.
Unsweetened cocoa powder 75 g (3/4 cup): Use Dutch-process for a deeper flavor, or natural cocoa for brighter acidity. Blooming cocoa with hot liquid improves aroma.
Baking powder 10 g (2 tsp) and baking soda 5 g (1 tsp): Leavening balance — both are needed for lift and crumb color.
Fine salt 6 g (1 tsp): Enhances chocolate. If using Morton’s kosher salt, halve the amount; Diamond Crystal is less dense.
Buttermilk 240 ml (1 cup): Adds tang and reacts with baking soda for lift. Substitute 240 ml (1 cup) milk + 1 tbsp vinegar if needed.
Vegetable oil 180 ml (3/4 cup): Keeps cake moist and shelf-stable. Do not substitute with butter without changing texture.
Large eggs 2 (about 100 g or 3.5 oz total): Bind and enrich. For egg-free notes, see Variations.
Coca-Cola (regular) 240 ml (1 cup): Key flavor and moisture agent. Do not use diet soda — sweetness and body differ.
Hot water 120 ml (1/2 cup): Helps bloom cocoa and dissolve sugars.
Vanilla extract 10 ml (2 tsp): Rounds the flavors.

Frosting

Unsalted butter 115 g (1/2 cup): Softened. Adds richness.
Powdered sugar 300 g (2 1/2 cups), sifted: For smooth, glossy texture.
Unsweetened cocoa powder 30 g (1/4 cup): For chocolate depth.
Coca-Cola 60–90 ml (1/4–1/3 cup): Warmed; start with 60 ml and add to reach spreading consistency.
Pinch of salt and 5 ml (1 tsp) vanilla.

Essential Equipment

Two 9-inch round cake pans (9-inch/23 cm) — not 8-inch; the batter volume needs 9-inch to avoid overflow.
Electric mixer or sturdy whisk — a stand or hand mixer speeds the process.
Kitchen scale for accuracy — weighing flour and sugar improves consistency.
Rubber spatula for folding and scraping.
Instant-read thermometer (optional) to check doneness; the crumb should read ~96–99°C (205–210°F) for a fully set cake.
Cooling rack.
Parchment paper for lining pans.

Step-by-Step Instructions

Prep Time: 20 minutes. Cook Time: 30–35 minutes. Inactive Time (rest/cool): 1 hour. Total Time: about 1 hour 50 minutes. Servings: 12 slices.

Step 1: Preheat and prepare pans

Preheat the oven to 175°C (350°F). Grease two 9-inch (23 cm) round pans and line the bottoms with parchment paper. Dust lightly with flour and tap out the excess so cakes release cleanly. This takes about 5 minutes.

Step 2: Combine dry ingredients

Whisk 300 g (2 1/3 cups) all-purpose flour, 400 g (2 cups) granulated sugar, 75 g (3/4 cup) unsweetened cocoa powder, 10 g (2 tsp) baking powder, 5 g (1 tsp) baking soda, and 6 g (1 tsp) salt in a large bowl until homogenous. Sifting is optional but helps if your cocoa is lumpy. This step takes 1–2 minutes.

Step 3: Mix wet ingredients

In a separate bowl, beat 2 large eggs (about 100 g), 180 ml (3/4 cup) vegetable oil, 240 ml (1 cup) buttermilk, and 10 ml (2 tsp) vanilla until blended, about 30 seconds. Stir in 240 ml (1 cup) Coca-Cola. Mix just until combined. Total active time 1–2 minutes.

Step 4: Bloom the cocoa

Pour 120 ml (1/2 cup) hot water into the dry mix and whisk quickly to dissolve. The batter will smell deeply chocolatey and thin. This helps bloom the cocoa and evenly distribute the chocolate flavor. Do this for 30 seconds.

Step 5: Combine wet and dry

Pour the wet mixture into the dry ingredients and stir with a spatula until no dry streaks remain. Do not overmix — stop as soon as the batter is uniform. Batter will be thin; that’s correct. This takes 45–60 seconds.

Step 6: Bake

Divide batter evenly between the two prepared pans. Bake at 175°C (350°F) for 30–35 minutes, rotating halfway if your oven has hot spots. Cakes are done when a toothpick comes out with a few moist crumbs and the top springs back, about 32 minutes. Use an instant-read thermometer if unsure; a safe internal temperature is ~96–99°C (205–210°F).

Step 7: Cool

Let cakes cool in pans on a rack for 10 minutes, then invert onto the rack to cool completely, about 45 minutes. Do not frost a warm cake or the frosting will melt. Cooling time is inactive.

Step 8: Make the Coca-Cola frosting

Beat 115 g (1/2 cup) softened unsalted butter until creamy, 1–2 minutes. Add 300 g (2 1/2 cups) sifted powdered sugar, 30 g (1/4 cup) cocoa powder, and a pinch of salt. Add 60 ml (1/4 cup) warmed Coca-Cola and 5 ml (1 tsp) vanilla; beat until smooth. If too thick, add up to 30 ml (2 tbsp) more cola. This takes 3–4 minutes.

Step 9: Assemble and chill

Place one layer on your cake plate and spread a thin coat of frosting. Top with the second layer and frost the top and sides. Chill for 20–30 minutes to set the frosting, then serve at room temperature. Allow 30–40 minutes for assembly and chilling.

Expert Tips & Pro Techniques

Measure by weight. Volume spoons and cups vary; a scale eliminates guesswork.
Common mistake: overbaking. Start checking at 28 minutes and use crumbs on a toothpick as your cue. Overbaked cake becomes dry quickly.
Use room-temperature eggs and buttermilk to help ingredients emulsify and produce a smoother batter.
Make-ahead: Bake layers up to 2 days ahead, wrap tightly, and refrigerate. Bring to room temperature before frosting for best texture.
Pro technique: Warm the Coca-Cola before adding to the frosting for better incorporation and a glossy finish. Warm to about 40°C (104°F), not boiling.
If you don’t have buttermilk, combine 240 ml (1 cup) milk with 15 ml (1 tbsp) white vinegar and rest 5 minutes until slightly thickened.

Storage & Reheating

Refrigerator: Store unfrosted layers or frosted cake in an airtight container or wrapped in plastic wrap for up to 4 days. Keep away from strong odors.
Freezer: The cake freezes well. Wrap individual unfrosted layers tightly in plastic and foil. Freeze up to 3 months. Thaw overnight in the fridge, then bring to room temperature before frosting or serving.
Reheating: Serve at room temperature. If you prefer warm slices, warm a slice in a 160°C (325°F) oven for 8–10 minutes. Avoid microwaving — it can make the crumb gummy.

Variations & Substitutions

Gluten-Free Version: Replace 300 g (2 1/3 cups) all-purpose flour with 330 g (2 1/3 cups by cup measure) 1:1 gluten-free flour blend and add 1/2 tsp xanthan gum if the blend lacks it. Baking time may increase by 2–4 minutes.
Egg-Free Version: Use 2 flax eggs (2 tbsp ground flax + 6 tbsp water, rested 10 minutes). Texture will be slightly denser and crumb a touch more tender. Increase baking time by 3–5 minutes.
Coffee-Boosted: Replace hot water with hot brewed coffee 120 ml (1/2 cup) to deepen chocolate flavor. Keep everything else the same.
Layered Trifle: Crumble cooled cake and combine with whipped cream and fresh berries for a quick trifle. Use the same frosting thinned with 30 ml (2 tbsp) milk as a drizzle.
Bundt Adaptation: Pour batter into a well-greased 10–12 cup bundt pan. Bake at 175°C (350°F) for 40–50 minutes, testing with a skewer. For a different presentation, see our chocolate bundt cake notes.

Serving Suggestions & Pairings

Serve with a scoop of vanilla ice cream and a drizzle of warmed chocolate sauce for contrast.
Pair with a cup of strong black coffee or espresso to cut sweetness. See our take on intense chocolate treats like double dark chocolate cupcakes.
Fresh berries (raspberries or strawberries) add bright acidity and color.
For a southern diner feel, serve with a simple glass of cold milk and shortbread on the side.

Frequently Asked Questions
Q: Why did my cake turn out dense instead of light?
A: Dense cake is usually from overmixing or too little leavening. Mix until combined and measure baking powder/soda by weight for accuracy.

Q: Can I make this without eggs?
A: Yes. Use two flax eggs (2 tbsp ground flaxseed + 6 tbsp water). Expect a slightly denser, moister crumb and increase bake time by 3–5 minutes.

Q: Can I double this recipe for a larger gathering?
A: Yes. You can double the batter and bake in four 9-inch pans or in sheet pans, but bake times will vary. Watch for the toothpick test and adjust by 5–10 minutes depending on pan depth.

Q: Can I prepare this the night before?
A: Absolutely. Bake the layers the day before, wrap tightly, and refrigerate. Bring to room temp before frosting, or frost chilled layers and serve the next day.

Q: How long does this cake keep in the fridge?
A: Frosted cake will keep 3–4 days in the refrigerator in an airtight container. Unfrosted layers last about the same if wrapped well.

Q: Why did the frosting turn runny?
A: Runny frosting often means too much liquid (Coke) or butter that’s too warm. Chill 10–15 minutes and then stir; if still thin, add 30–60 g (1/4–1/2 cup) more powdered sugar.

Q: Can I use diet soda or flavored cola?
A: Avoid diet sodas; they lack body and sweetness. Flavored colas (cherry, vanilla) will change the cake’s flavor profile; use only if you want that twist.
