Ruby Chocolate Cake Ingredients

• Here’s what you need to whip up this delicious Ruby Chocolate Cake recipe!

For the Cake

All-Purpose Flour – Provides structure and stability; swap with gluten-free blend if needed.
Granulated Sugar – Adds sweetness and helps achieve a light texture; no direct substitutions recommended.
Cocoa Powder – Essential for chocolate flavor; opt for unsweetened natural cocoa over Dutch Process for best results.
Baking Soda & Baking Powder – Key leavening agents for a fluffy cake.
Kosher Salt – Enhances flavor; regular salt works too.
Vegetable Oil – Keeps the cake moist; use melted coconut oil for a slight flavor twist.
Eggs – Provide moisture and binding; for vegan options, use flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg).
Pure Vanilla Extract – Adds depth; almond extract can be used for variation.
Buttermilk – Ensures tenderness; make a quick DIY version with vinegar and milk.
Hot Water – Activates cocoa for improved texture.

For the Ruby Chocolate Buttercream

Ruby Cacao – Main ingredient that offers fruity, chocolaty notes; choose ruby chocolate bars or chopped pieces.
Unsalted Butter – Creates a creamy texture; vegan butter is a good alternative.
Powdered Sugar – Sweetens the frosting adequately; use a small amount to balance with chocolate.
Heavy Whipping Cream – Lightens the buttercream; milk can be a substitute for a lighter texture.
Kosher Salt – Essential for balancing flavors.

For the Ruby Chocolate Ganache

Ruby Cacao – Same main flavor component used in the buttercream; ensures consistency in taste.
Heavy Whipping Cream – Creates a smooth ganache; coconut cream works for a dairy-free version.

How to Make Ruby Chocolate Cake

Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures the cake will bake evenly and rise perfectly.
Prepare Cake Pans: Grease and line your cake pans with parchment paper. This makes it easier to remove the layers once they’re baked.
Mix Dry Ingredients: In a large mixing bowl, whisk together all-purpose flour, cocoa powder, baking soda, baking powder, and kosher salt until well combined.
Incorporate Wet Ingredients: Add the granulated sugar, vegetable oil, eggs, pure vanilla extract, and buttermilk to the dry mixture. Stir until everything is blended, but take care not to overmix.
Add Hot Water: Gradually pour in the hot water, stirring until you have a smooth batter. The hot water helps activate the cocoa powder for a richer flavor.
Divide and Bake: Evenly divide the batter between your prepared cake pans. Bake in the preheated oven for 40-45 minutes until a toothpick inserted into the center comes out clean.
Cool Completely: Remove the cakes from the oven and let them cool in the pans for about 10 minutes. Carefully transfer to a wire rack to cool completely before frosting.
Make the Ruby Chocolate Buttercream: Melt the ruby cacao and allow it to cool. In a mixing bowl, beat the unsalted butter until fluffy. Gradually add powdered sugar, followed by the melted ruby cacao, cream, and a pinch of kosher salt. Mix until smooth and creamy.
Prepare the Ganache: Heat heavy whipping cream in a saucepan until it just begins to boil. Pour it over the chopped ruby cacao and let it sit for about 20 seconds, then stir until it becomes smooth and glossy.
Assemble the Cake: Once the cake layers are cooled, level them if necessary. Spread a layer of ruby chocolate buttercream between the layers, then frost the top and sides. Chill the cake for 20 minutes to allow the frosting to set.
Finish with Ganache: Drizzle the prepared ganache over the top of the cake, letting it dribble down the sides. Chill for another 5 minutes to set. Decorate with any remaining buttercream as desired.

Optional: Garnish with fresh raspberries for an added fruity touch.

Storage Tips for Ruby Chocolate Cake

Room Temperature: Store leftover ruby chocolate cake in an airtight container at room temperature for up to 3 days to keep it fresh and moist.

Fridge: If you prefer to keep it longer, refrigerate the cake for up to a week. Make sure it’s well-wrapped to prevent drying out.

Freezer: For longer storage, you can freeze un-frosted cake layers for up to 2 months. Wrap each layer in plastic wrap followed by aluminum foil. Thaw at room temperature before frosting.

Reheating: If you want to enjoy a slice warm, gently microwave for 10-15 seconds to warm it. This can enhance the chocolatey goodness of your ruby chocolate cake!

Expert Tips for Ruby Chocolate Cake

Room Temperature Butter: Ensure your butter for the buttercream is at room temperature. This allows for smoother mixing and a creamier texture that elevates your Ruby Chocolate Cake.
Don’t Overmix Batter: Gently fold the wet and dry ingredients; overmixing can lead to a dense cake. Aim for a smooth batter for the best results.
Level Cake Layers: When cooling, check that cake layers are level. Trim them if necessary to ensure stability when stacking, especially for the Ruby Chocolate Cake.
Test Ganache Consistency: Before drizzling ganache on the entire cake, do a test drip. This helps you adjust the thickness to achieve that perfect chocolaté flow!
Chill for Better Frosting: After frosting the assembled cake, chill it for at least 20 minutes before adding ganache. This sets the buttercream and prevents it from mixing into the ganache.
Mix Up Flavors: Experiment by adding extracts like almond or variations with berry frostings. This can add a delightful twist to your Ruby Chocolate Cake recipe!

Make Ahead Options

These Ruby Chocolate Layer Cake preparations are ideal for busy home cooks looking to save time! You can bake the cake layers up to 2 days in advance; simply wrap them in plastic wrap once completely cooled and refrigerate. The ruby chocolate buttercream and ganache can also be made up to 3 days ahead—just store them in airtight containers in the fridge. To maintain the buttercream’s smooth texture, rewhip it lightly before frosting. When ready to serve, layer the cooled cake with buttercream and apply the ganache, allowing a brief chill to set everything beautifully. This way, your decadent Ruby Chocolate Layer Cake will be just as delicious with minimal effort!

Ruby Chocolate Cake Recipe FAQs

How do I select the right chocolate for my Ruby Chocolate Cake?
Absolutely! When choosing ruby cacao, look for high-quality ruby chocolate bars or chopped ruby chocolate to ensure you get the best fruity and chocolaty notes. Always check the cocoa percentage; aim for one around 30% to maintain that rich flavor without being overly sweet.

What’s the best way to store leftover Ruby Chocolate Cake?
I recommend keeping your leftover cake in an airtight container at room temperature for up to 3 days. If you want it to last longer, it’s perfectly fine to refrigerate it for about a week—just ensure it’s well-wrapped to keep the moisture in and the texture fresh.

Can I freeze my Ruby Chocolate Cake?
Yes, you can! For best results, freeze the un-frosted cake layers for up to 2 months. Here’s how: wrap each layer tightly in plastic wrap, then cover with aluminum foil to prevent freezer burn. When you’re ready to frost, simply thaw them at room temperature for a couple of hours before applying your buttercream.

What should I do if my cake doesn’t rise properly?
Very important! If your cake isn’t rising, check if your baking soda and baking powder are fresh; they can lose potency over time. Also, make sure you’re measuring your ingredients accurately—too much flour or insufficient liquid can affect the rise. Mix the dry and wet ingredients just until combined, avoiding overmixing, which can also lead to a dense cake.

Can I make this Ruby Chocolate Cake vegan?
Absolutely! To make it vegan, you can replace eggs with flax eggs (1 tbsp ground flaxseed mixed with 3 tbsp water for each egg). Additionally, swap the buttermilk with a dairy-free alternative—just mix 1 tbsp vinegar with 1 cup of your favorite plant milk instead. Enjoy a delicious dairy-free masterpiece!

Can pets eat ruby chocolate?
No, chocolate in any form is toxic to pets, especially dogs and cats. Always keep your ruby chocolate cake out of their reach and inform guests not to share any of it with your furry family members.
