There is no candy that I love more than Cadbury Mini Eggs, so when the grocery stores start putting out their Easter candy I always have a steady stash of them in my cupboard. They do not last long in this house. Even Theo is obsessed with what he calls “bwoo eggs” (blue eggs). For Easters’ past I have been known to decorate cakes with these classic little pastel eggs but this year I decided I needed the flavor to be a showstopper as well. So I found a really fun and INCREDIBLY TASTY way to add the distinct flavor of Cadbury Mini Eggs throughout the cake and I can’t wait for you to try it!

This Cadbury Mini Egg cake recipe starts with my favorite one bowl chocolate cake, which is delicious all on its own, but what takes it to legendary status is the Cadbury Mini Egg ganache filling. It’s a super creamy chocolate filling made by melting the Mini Eggs with simmered heavy whipping cream until it’s silky smooth with little bits of candy shell throughout. It sets into a silky smooth, decadent ganache filling that will absolutely blow your mind! And even though the idea of ganache filling might sound extravagant if you’ve never made it before, I promise you it’s super easy to whip up in minutes.
For the topping, I used my favorite vanilla buttercream recipe, dyed those signature pastel colors to match the Mini Eggs. I created an ombrè finish with pastel blue, yellow, and pink buttercream before finishing the look with some piped buttercream “nests” filled with more Mini Eggs.
Fun fact: I actually turned the leftover buttercream from the ombrè into chocolate buttercream for those nests! After frosting the cake, I simply added the remaining buttercream into a bowl and mixed it all together with 2 teaspoons of cocoa powder and boom. Delicious chocolate buttercream with zero waste.
Whether you’re celebrating Easter and need a centerpiece dessert or you simply want to welcome Spring with a fun cake, this recipe is the perfect baking project. Feel free to get creative with the decorating or replicate this look using the Assembly instructions below! However you dress it up, this cake tastes just like Cadbury Mini Eggs in cake form and will make every Cadbury fan swoon.

- 2 tsp baking soda
- 1 tsp baking powder
- 1/2 tsp kosher salt
- 1/2 Cup (120ml) vegetable oil
- 2 large eggs, room temperature
- 1 1/2 tsp pure vanilla extract
- 1 Cup (240ml) full fat buttermilk, room temperature* DIY recipe in notes
- 1 Cup (240ml) hot coffee or hot water
Cadbury Mini Egg Ganache
- 1 Cup (212g) Cadbury Mini Eggs
- 1/2 Cup (120ml) heavy whipping cream
Vanilla Buttercream
- 2 Cups (452g) unsalted butter, room temperature
- 7 Cups (840g) powdered sugar
- 4 tsp pure vanilla extract
- 3 Tbsp whole milk, room temperature
- pinch of salt
- Pink, yellow, and blue food color gels
Nests
- 2 tsp cocoa powder
- 18 Cadbury Mini Eggs
Instructions
Make the Chocolate Cake
- Preheat the oven to 350ºF and prepare three 6-inch or two 8-inch cake pans by spraying the sides with cooking spray and fitting the bottoms with a wax paper or parchment cake circle.
- Place all of the dry ingredients into the bowl of a stand mixer and stir on low for 30 seconds to fully combine them. Add the vegetable oil, eggs, vanilla, and buttermilk and mix on low until just combined. With the mixer still on low, add the hot water in a slow stream, then turn the mixer to medium and beat until smooth, about 2 minutes. The batter will be very thin.
- Pour into prepared cake pans no more than 2/3 full and bake for 32-36 minutes, until a toothpick inserted comes out clean. Cool completely before filling and frosting.
Make the Cadbury Mini Egg Ganache
- Pour the heavy whipping cream into a small saucepan set over medium heat and bring to a simmer, whisking frequently. Meanwhile, place the Cadbury Mini Eggs in a glass bowl and microwave them in 30 second increments, until the shells crack under slight pressure and the chocolate inside looks melty. In my experience it took 2.5 intervals (so, 1 minute 15 seconds).
- When the heavy whipping cream starts to simmer, pour it over the Cadbury Mini Eggs and cover the bowl with a plate for 2 minutes. Afterwards, whisk the mixture into a uniform consistency, breaking down the shells as you go. It will look pretty rough at first, but I promise it will come together in 1-2 minutes of whisking. When it's fully combined it will look like smooth milk chocolate ganache with tiny bits of candy shell throughout.
- Place a piece of plastic wrap over the surface of the ganache and place in the refrigerator for 1-2 hours, until completely cooled and the consistency is much thicker, almost like Nutella.
Make the Vanilla Buttercream
- With a hand mixer or paddle attachment on your stand mixer, cream the butter on medium-high until it’s creamy and light (almost white) in color. About 7 minutes.
- With the mixer on low, add the powdered sugar a few cups at a time, scraping down after each addition and making sure each is fully incorporated before adding the next one.
- Add vanilla, milk, and salt and mix on low for another minute until fully incorporated.
Assembly
- Once the chocolate cake layers have cooled completely, level and torte each layer to your desired height. Place the first layer on a turntable and pipe a circle of vanilla buttercream around the edge. Fill in the center with half of the (room temperature) Cadbury Mini Egg ganache. Here's a detailed tutorial on this filling method in case this is your first time working with a soft filling.
- Place the next cake layer on top and repeat the process of piping the buttercream circle and filling in the center with the rest of the Cadbury Mini Egg ganache. Place the final layer on top, upside down so that the bottom of the cake layer is the top of the cake. Crumb coat the cake with vanilla buttercream and place it in the refrigerator for at least 20 minutes to let everything set up.
- Color the Buttercream: Divide the rest of the vanilla buttercream between three bowls and make sure one of the bowls has about 1/2 Cup more buttercream than the other two. Use food color gels to tint one bowl pastel pink, one bowl pastel yellow, and the bowl with the most buttercream periwinkle blue.
- Create the Ombrè Finish: Add each buttercream color into a piping bag and snip off the end. Starting at the bottom of the cake and working your way up, pipe the yellow buttercream while you turn the turntable until it reaches about 1/3 of the way up the cake. Continue on with the pink buttercream until you reach 2/3 of the way up the cake. Finish with the blue buttercream for the top third of the cake and the very top. Use an icing smoother to create a smooth buttercream finish with the ombrè colors, then place the cake into the refrigerator for 20 minutes to let the buttercream set.
- Make the Nests: Place the remaining colored buttercream into a bowl and add 2 tsp of cocoa powder on top. Mix until you have a uniform chocolate buttercream and add it into a piping bag fitted with Wilton Tip 4B. Pipe 6 nests on top of the cake. I basically piped a circle with another circle on top. Add 3 Cadbury Mini Eggs into each nest.
Notes
- The chocolate cake can be made ahead and stored at room temperature, covered tightly in plastic wrap, for up to two days. Alternatively, you can cover with plastic wrap and store in the freezer for up to two months before thawing to room temperature.
- The Cadbury Mini Egg Ganache can be made up to a week in advance and stored in an airtight container in the refrigerator. Bring it back to room temperature before using as a filling. You may need to microwave it for 5-10 seconds to get it nice and creamy.
- The vanilla buttercream can be made ahead and stored in an airtight container in the refrigerator for up to two weeks. When you’re ready to use it, bring it back to room temperature and re-whip in your stand mixer to bring back to smooth buttercream consistency.

I made this recipe at Easter and it was a hit with everyone. I usually use a chocolate cake recipe that I’ve used tons of times but decided to give this one a try. I loved it, it will have to be in rotation with my other one. The ganache was really good. The shells of the Cadbury eggs don’t stay crispy after a day but they still add something to the ganache. Will definitely make again!
Hi,
If you use two 8inch cake pans would you make it into 4 layers or leave as two???
Thank you
Hi Nicole! I usually just leave it as two 8-inch layers, but you could torte them into four if you want.
Question! Is this ganache firm enough to be used as a macaron filling? Or is it a bit too soft?
Hi Kim! You could totally use it as a macaron filling. I’d break the shells down as small as possible so you can pipe it into the centers easily.
Oh my goodness!!!! this cake is SOOO adorable…. Might be my next make! I love the Easter theme. Thanks for amazing recipes and tips Whitney!
Yay, Addie! I hope you get a chance to make this one, it turned out so tasty!
