Ingredients Needed
Here are some notes on the ingredients we'll be using. For the full ingredients list, look at the recipe card below.
- Cocoa Powder: I used Hershey's natural unsweetened cocoa powder. Make sure to sift the cocoa powder before using.
- Leavening Agents: Both baking soda and baking powder are used.
- Milk: I used 2% milk, but you can use whatever milk you prefer.
- Oil: You can use either vegetable oil or canola.
- Unsalted Butter: Be sure this is at room temperature.
- Peppermint Extract: Use pure peppermint extract and be careful with how much you use. Do not add extra.
- Green Food Dye: I recommend using a gel food dye like this one.
- Andes Mints: If you can buy these in bulk, you need a total of 40. If not, you'll need to buy 2 packages.
- Chocolate: Use a good quality chocolate for the ganache. I used Scharffen Berger.
Instructions
Here are the step by step instructions on how to make this Andes Mint cake.
Step 1: Dry ingredients. In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
Step 2: Wet ingredients. In a medium-sized mixing bowl, whisk together the warm water, milk, eggs, vegetable oil, and vanilla extract until combined.
Step 3: Combine the ingredients. Slowly add the wet ingredients into the dry, whisking until a wet batter forms.
Step 4: Bake. Divide the batter amongst the three prepared cake pans and bake for 23-28 minutes, or until a toothpick inserted into the middle of the cakes come out clean.
Step 5: Make the frosting. Beat together the butter until light and creamy in the bowl of a stand mixer. Add the powdered sugar, heavy whipping cream, vanilla extract, and peppermint and mix on low until combined.
Add 1-2 drops of the green food coloring and beat on high for 1-2 minutes until creamy.
Step 6: Make the ganache. In a small bowl, heat the heavy whipping cream until bubbling. Pour the heavy cream over the chocolate and allow it to sit for 3 minutes.
Add the peppermint extract and whisk together until smooth.
Assembling The Cake
Make sure the cake layers are completely cooled before assembling and decorating.
First, level off the tops of each cake layer to create a flat surface using a serrated knife. Place one cake layer on a cake stand or plate and spread about ⅔ cup of frosting (I use my offset spatula to make it easier).
Add 15 chopped up Andes Mints. Repeat with the second layer. Top the cake with the last layer and spread on about ¼ cup of frosting.
Next, frost and smooth the outside of the cake with a thin crumb coat. Place the entire cake in the refrigerator or freezer for 10 minutes to chill.
Finish frosting the cake with the remaining buttercream, pour on the chocolate ganache, and top with extra Andes Mints.
Storage Tips
Keep any leftover cake slices in an airtight container in the refrigerator for up to 5 days.
You could also wrap each individual cake slice in plastic wrap before placing it into the refrigerator. This helps the cake to not dry out.
Expert Baking Tips
- Cake Pans: For this recipe, I used three 6-inch cake pans, but you could also use two 8-inch or two 9-inch cake pans (the baking time may be different). Prepare each cake pan by lining them with parchment paper and then non-stick spray.
- Mint Flavor: I used peppermint extract but be careful. If you add too much, everything will taste like toothpaste.
- Crumb Coat: This is where we add a thin layer of frosting on the cake in order to catch the crumbs and keep them secure. You’ll want to chill the cake in the refrigerator or freezer for 10 minutes after the crumb coat has been put on before the final frosting layer.
- Cake Decorating Tools: I like to use a turntable, cake scraper, and an icing spatula to help assist me when assembling a cake.
Recipe FAQs
I used three 6-inch cake pans, but you could also use two 8-inch or two 9-inch cake pans.
Yes you can. Simply bake the cake layers the day before, wrap them in plastic wrap, and leave them on the counter at room temperature overnight. Frost and decorate the next day.

- Pour the chocolate ganache over the top of the cake, allowing it to drip down the sides. I added 10 more Andes Mints to the top of the cake (chopped).
- Refrigerate the cake for at least 15 minutes before serving so it's easier to cut. Keep any leftover cake slices in an airtight container in the refrigerator for up to 5 days.
