Perfectly moist, perfectly chocolate and perfectly perfect for any gathering or holiday this simple chocolate peppermint cake is the best holiday cake.

We’ve been working with McCormick for a few years now, and when the opportunity came to learn more about what to look for in quality spices, herbs and extracts leading up to the holiday cooking season, we knew this was going to be one of our favorite posts yet.

We’ve been asking questions for months now about what people love to eat around the holidays and although I’m a little sad that I didn’t see more pie answers as, it is the greatest thing in the world – I was excited to see so many request a super easy holiday inspired cake. Well we can do that!

You know we’ve always been fans of using really high quality ingredients and we’ve often tried to encourage our readers to use quality herbs, spices, and extracts as it makes such a huge difference in cooking, but this was our chance, our chance to talk with a chef and do a blind taste testing which would really tell us if everything we’ve been saying would hold true.

We had two unmarked containers of cinnamon, thyme and peppermint. I don’t know why, but even when it’s a brand I love I tend to go completely neutral as I really like the results to teach me something.

First we learned a few fun facts:
*Cinnamon comes from the bark of a tree and it begins to grow back almost immediately when cut down.
*Thyme should be uniform in size, a little more green or sage in color

*Peppermint not only does NOT taste like peppermint mouth wash as you may be quick to assume since that is pushed so much in products, but instead it’s a cool, more subtle flavor AND it not only tastes that way but peppermint actually has a cooling affect. Try it, grab a McCormick Pure Peppermint extract and another brand and see which one is more medicinal and which one is subtle with a cooling affect. It’s cool, literally, haha!

It all worked!!! The flavors I preferred (there was one that literally smelled and tasted dusty) all turned out to be McCormick. So many readers have told us that changing out their spices really did make a difference in their cooking.

I love when someone says they thought their food never turned out as good as the recipe made it sound until they realized they just weren’t using very good ingredients.

The little things really do make a difference! Which is why we are going to go over the cake and frosting really quick.

- Simple Chocolate peppermint cake loves oil, water, and yogurt or sour cream. We prefer canola oil, but vegetable is great and while we used sour cream you absolutely can use Greek yogurt, just make sure it’s plain and not vanilla or any other flavor.
- Cake does not want to be over-mixed. It’s hard, I know. I want to keep stirring that beautiful, silky batter too, it’s just so therapeutic to stir! It’s also what will create a flat, dry cake. Do not over-mix.
- Use Miracle Pan Release. I love using THESE parchment rounds but if I don’t have any I never just spray and flour. Maybe it’s me but I always end up with a cake that sticks.
- Frosting loves simplicity. You may want to add more peppermint or white chocolate or even food coloring for more swirls, but trust me, keep it simple and it will beautifully compliment the cake. When you use Pure Peppermint Extract like the one from McCormick you’ll notice that the flavor takes care of itself.
What Can You Substitute For Sour Cream?
Plain or Greek yogurt can be substituted for sour cream.
Add a teaspoon of lemon juice to 1 cup yogurt.

We tested and retested the cake and then of course on photographing day I forgot to rap the pans on the counter to get rid of the airbubbles so as you can see, the top layer is holey, not to be confused with holy. 😉 I almost remade it, but then I decided something, one of you are bound to do the same, and if you’re anything like me sometimes the perfection of pinterest and blogs can be daunting so know this, I messed up our simple chocolate peppermint cake and you can too and as long as the flavor is good, who cares?!

How Long Will Chocolate Cake Keep?
Properly stored, freshly baked chocolate cake will last for about 1 to 2 days at normal room temperature.
*Refrigerate immediately any cake that contains frosting or filling made with dairy products or eggs, such as buttercream, whipped cream or custard frostings or fillings.

This cake and especially the frosting were so delicious that I haven’t been able to stop thinking about it. Has anyone made it into cupcakes? How long did you cook them for and what temperature was your oven?
Thank you so much Bridget! You make these into cupcakes easily! Keep the temperature the same and back them for 18-20 minutes.
What size cake mix did u use? The old size 18 oz or new 15 oz?
The 15.25oz size you can buy now.
Yogurt or sour cream?
Yes, you can use either one. We used sour cream, but you could use plain Greek yogurt. Just make sure it isn’t vanilla or any other flavor.
The Simple Chocolate Peppermint cake recipe/directions NEVER say when to add the chocolate pudding mix!!!
It has been corrected! Sorry about that! It goes in with the cake mix.
EIGHT cups powdered sugar for the frosting? Did I read that right?
Yes! It takes a lot of frosting to cover all that deliciousness!
So I made this cake, it turned out very dry. I noticed it said cake loves oil but in the recipe no oil is listed. What did I do wrong?
Oh Kristy!! I’m so sorry. We are editing our recipe box and so it must not have been loading at the same time for you. It’s all there now.
