Chocolate Birthday Cake Ingredients

Ingredients in white bowls to make a chocolate layer cake for a birthday on white countertop
  • Large Eggs: Make sure these are room temp.
  • Granulated Sugar: Swap in homemade brown sugar for an even more tender cake.
  • Cocoa Powder: I use unsweetened cocoa powder here.
  • Instant Coffee Powder: This intensifies the chocolate flavor. Swap in your fave cup of coffee and just leave out the coffee powder.
  • Salt: Just a pinch is all that’s needed.
  • Hot Water: Again, you can use coffee here.
  • All-Purpose Flour: I don’t recommend using cake flour here since it will make our cake too soft to work with.
  • Baking Soda & Baking Powder: Make sure you check the expiration dates on these before using.
  • Vegetable Oil: Any neutral oil like canola will also work here.
  • Buttermilk: None around? Make some by adding a tablespoon of lemon juice or vinegar to 1 cup of milk and letting it sit for 5 minutes until it thickens.
  • Pure Vanilla Extract: Don’t use artificial here.
  • Unsalted Butter: Just leave out the salt if you use salted butter here.
  • Confectioner’s Sugar: I like to sift this so the frosting turns out smooth.
  • Cocoa Powder: Unsweetened is best here.
  • Milk: Use any you prefer. It just helps smooth the consistency.

Notes

How to Store

Wrap your leftovers tightly in plastic wrap or place it in an airtight container or cake carrier to keep it fresh and fab for up to 3-4 days at room temp. If you need to keep it longer than that, slide the extra cake into the fridge.
Just a little tip: if you’re diving back in for another slice, let it sit out for a bit to get back to room temperature – it’ll taste just like it did on day one!

How long will chocolate birthday cake last in the fridge?

It’ll stay scrumptious for up to 6 days.

Can I freeze ?

Absolutely boos! I like to chill the cake in the fridge first to get that frosting firmed. Then I cut individual slices and wrap them tightly in plastic wrap then add to freezer bags releasing all the air. Add the date. It should last in the freezer for up to 3 months. Thaw in the fridge then bring back to room temperature before indulging.

Recipe Tips

  • Don’t Skip the Coffee: This really does add a richer chocolate flavor to the mixture. You won’t even taste the coffee boos, trust me.
  • Don’t Overbake: Make sure you watch that bake time so you don’t dry out your cakes.
  • Cool Completely Before Frosting: If you don’t want a super melty cake sliding around everywhere, make sure that the cake layers have cooled completely before frosting.

How do I prevent my cake layers from sticking?

I like to grease my round pans with cake release then add parchment to the bottoms so the layers come out super clean y’all.

Can I make this chocolate birthday cake ahead?

Absolutely boos. In fact, you can bake the cake layers and freeze them by wrapping them tightly with plastic wrap a few times. When you are ready to serve, pop them in the fridge to defrost. Then make the frosting fresh, ice your cake and serve it up.

  1. My birthday is coming I usually make myself a delicious chocolate cake and homemade frosting, but I’m going to try this one, I love a chocolate cake.

  2. It’s my third time making this cake …this month! I made it for my husband and my mom …this morning I made it for my own birthday! I can’t begin to describe how absolutely PERFECT this recipe is …and I’ve made many cakes over the years.

    I have made this and the lemon pound cake …it brings me SO MUCH joy and a few added inches that are well worth it!

    Thank you for sharing your family’s traditions!

  3. Am dying to make this! Do you think I’d be able to substitute sour cream for the butter milk? I don’t have any by me! And what kind of cocoa powder do you use? Natural or Dutch?
    Thanks!!

  4. All I have to say is AMAZING!! This cake made my dad’s birthday celebration. It’s the best chocolate cake I’ve ever had. Even my boyfriend, who doesn’t like cake gobbled up his piece. It’s also easy to make for first time bakers 🙂 enjoy!

  5. I made this 6 days ago (yes …I am counting) for my husband’s birthday. It was hectic – I made my own buttermilk, didn’t have an appropriate oil on hand and used butter and added the flour before the coffee. It was the MOST AMAZING chocolate cake I’ve ever made. Moist and so full of flavor. My husband and I finished it off and I’ll be making another today to celebrate my Mom. Then …another on the 22nd as I’ve told everyone I’ll make my own cake because nothing compares!
    I should also share – Chocolate cake is my hubby’s fave. I’m a lemon or pound cake girl. Until now …

    THANK YOU!! ❤️

    1. I meant to clarify that even all of my “hectic day” blunders didn’t change the fact that this was AMAZING!!

  6. This was the best chocolate cake I’ve ever had! Made it for my son’s 3rd birthday and the moment everyone had a bite they were all amazed! So glad I found this recipe and can’t wait to go through and start cooking my way through the rest of the Grandbaby Cakes site!

  7. Thanks Guys, Your Recipe Was Too Fantastic. Me and My Family Loved it. I Will Share your Rrecipe with my friends. Hope they will love it too.

  8. Thanks Guys, Your Recipe Was Too Fantastic. Me and My Family Loved it. I Will Share your Rrecipe with my friends. Hope they will love it too.
