    Funfetti Cake with Chocolate Buttercream

    Hi hi! I want to start this post out by confessing that I think I’m breaking the funfetti rules with this cake. Apparently, according to the internet, funfetti cake is a place of white cake, imitation vanilla and sprinkles. I didn’t grow up with white cake (just ‘yellow’ cake which is what we call vanilla cake), so when I set out to make a funfetti cake, I wanted to keep it as delicious and flavourful as possible, so here we are - funfetti in a yellow cake. Don’t come at me, because it’s really, really good.

    I used my favourite vanilla bean cake as a base here for this funfetti cake, but switched out the milk in the recipe for buttermilk, just for a tiny bit more moisture. The cake is my ultimate base recipe - you can infuse the milk to flavour it, and it makes a great sheet cake, snack cake or cupcake base. Because it’s such a great base, it also handled me throwing a whole heap of sprinkles at it like an absolute champ. The cake is super tender, packed with flavour, and is an amazing homemade funfetti cake recipe, as far as I am concerned. It uses the reverse creaming method - where you mix together all the dry then incorporate in the butter and then the wet ingredients, which is not only super easy but gives an incredibly tender crumb. It’s just the best.

    What are the best sprinkles to use in Funfetti Cake?

    I found that the best sprinkles to use for this funfetti cake were jimmies - if you’re in New Zealand those are the long skinny rainbow ones, the colourful version of chocolate hail. The round confetti ones would work too, just stay away from nonpareils (hundreds and thousands) because they lose their colour and it gets messy quickly.

    I finished the funfetti cake off with a dark chocolate butter cream. I first discovered it on my friend Claudia’s site, by way of our other friend Thalia’s site, and it is so good! It is an american buttercream base, but is amped up with dutch cocoa and melted chocolate - imagine ganache and american buttercream had a baby. American buttercream is generally powdered sugar based, and can get a wee bit grainy, but this is fluffy and silky, and so, so good, and is perfect paired with the buttery, rich, sprinkle packed funfetti cake.

    A few wee tips for making this Funfetti Cake

    • I use Fat Daddio’s pans and they are the best I’ve ever tried. I have three 6” and three 8” and they are just so, so good. I really recommend investing in three of each size if you can - it removes the need to halve your layers etc, which can be a huge pain.

    • I like making the cake ahead of time a wee bit if I can just to allow it to cool completely. The day before is great. You can wrap it and store at room temperature overnight, just make sure it is completely cool. Alternatively I like to freeze it, which makes the stacking process nice and easy to do with a cold cake. If you are making the layers ahead of time, wrap them well in plastic then freeze until you are using. I assemble straight from frozen usually - just make sure to give yourself enough time to let the layers defrost!

    • I left this pretty rustic around the edges and just added in some sprinkles, but if you like there is enough frosting in the recipe to finish with a border of piping if you liked.

    • If you want an 8” cake, just double the quantities of the cake and it will be the perfect size. You can probably get away with a 1.5x or 1.75x the buttercream quantity.

    • When you are dividing your batter between the pans, do it by weight. I like to know the weight of my mixing bowl before I start (write it somewhere in your kitchen), so I can just weigh the bowl filled with batter, and then subtract the bowl weight to get the weight of the batter. You can then work out how much batter goes in each pan. It’s quick and easy and means you get really even layers.

    • I like to use a cookie scoop to add the buttercream between the layers. that way you can easily add the same quantity between. Otherwise you can just eyeball it and plop the buttercream on!

    Description

    The most delicious, moist funfetti vanilla bean cake. This homemade funfetti cake has a yellow cake base and is made with buttermilk to keep it perfectly dense, and is packed full of Jimmy sprinkles. The confetti cake is layered with a rich chocolate American Buttercream frosting, and finished with more sprinkles. This is the perfect celebration cake, and at six inches it is great for a small group.


    Ingredients

    Scale

    Funfetti Cake

    • 2 large eggs, at room temperature
    • 1 egg yolk, at room temperature
    • 1 tsp vanilla bean paste
    • 200g buttermilk, at room temperature
    • 60g full fat greek yoghurt
    • 300g all-purpose flour
    • 225g sugar
    • 1 ¾ tsp baking powder
    • ½ tsp salt
    • 175g unsalted butter, at room temperature
    • 115g rainbow Jimmy sprinkles

    Dark Chocolate Buttercream

    • 225g 60% or higher chocolate, roughly chopped
    • 290g unsalted butter, at room temperature
    • 1 tsp salt
    • 225g powdered sugar, sifted
    • ½ tsp vanilla bean paste
    • 90g dutch process cocoa, sifted
    • 2-3 Tbsp heavy cream, as needed

    Instructions

    CAKE LAYERS

    1. Preheat the oven to 350°f / 180°c. Grease three 6” cake pans, and line with parchment paper on the bottom.
    2. In a medium bowl, whisk together the eggs, egg yolk, vanilla, buttermilk, and yoghurt.
    3. In the bowl of a stand mixer fitted with the paddle attachment, combine the flour, sugar, baking powder, and salt. Mix briefly to combine.
    4. With the mixer on low, add the butter a cube at a time, until fully incorporated and the mixture looks like sand.
    5. Add half of the wet ingredients into the mixer. Mix until just combined, then add the second half of the wet ingredients. Mix on medium speed until just combined. Add in the sprinkles and mix to combine.Remove the bowl from the mixer and give a few folds with a rubber spatula to ensure that no dry ingredients remain.
    6. Divide the batter between your three cake tins (I prefer to do this by weight - see notes). Bake for 25 to 30 minutes, or until the cakes are springy to the touch, and a skewer inserted into the middle comes out clean.
    7. Remove from the oven and cool for 15 minutes in their pans, then turn onto a wire rack and allow to cool completely.

    DARK CHOCOLATE BUTTERCREAM

    1. Melt the dark chocolate in 15 second increments in the microwave, stirring well between each until melted. Set aside to cool completely.
    2. In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on high speed until light and fluffy, approx. 4 minutes. Add the salt, powdered sugar, vanilla bean paste, and cocoa, and mix until smooth, scraping down the sides once or twice.
    3. Add the melted chocolate and mix well until silky. If needed, add cream 1 tbsp at a time to get the frosting to a nice smooth, fluffy consistency.

    ASSEMBLY

    1. Level off the cake layers. Secure one of the layers of cake to a cake turntable, cake stand or cake board using a little buttercream. Add about half a cup of buttercream onto the first layer of cake (I used a cookie scoop that had a 2 Tbsp volume and added 3 scoops), and smooth using an offset spatula.
    2. Place the second layer of cake onto the first, pressing very lightly to secure, and sealing the joins with a thin layer of buttercream. Add more buttercream, smooth down, then top with the third layer of cake - I like to put this one upside down to ensure that the top of the cake is flat.
    3. Crumb coat the cake - to do this, apply a thin layer of buttercream over the surface of the cake, and smooth with a bench scraper or icing smoother. Refrigerate the cake for 15-20 minutes, until the crumb coat has set. Press a piece of plastic wrap over the surface of the buttercream while you are chilling down the cake.
    4. If you have started with a chilled or frozen cake, or the buttercream seems to be not too sloppy, you can skip the chilling down of the crumb coat if you like, or reduce the time to 5 mins. If you have an empty freezer you can also throw it in the freezer for 5 minutes to help set it!
    5. Add a second layer of buttercream to the cake - I like to make this one thicker and smooth down the edges.
    6. Smooth the buttercream on the outside of the cake using a bench scraper, scraping down between passes. Fill in any gaps, and add additional buttercream where needed. Continue until you are happy with the finish.
    7. Chill the cake until you are ready to serve. Bring to room temperature for about an hour before serving.

      Loved this recipe! I've never tried the reverse creaming method before and it was super easy. I think the crumb of the cake itself wasn't as light, but dang it was so good!!

        Hi! I don't provide recipes in cups sorry as they are not accurate. You can read more about this on my FAQ page if you like. I test my recipes in grams so it does not make sense to then provide a less accurate measurement. By posting my recipes in grams I know my readers are making the recipe accurately. Happy to recommend a scale if you need one!

        Hiii! Yep it will be just fine, you will just need to scale the recipe. So to make an 8" three layer cake I would double this recipe (a 6" cake doubles to an 8"), so if you have 2 9" pans I would also make a double to give you a two layer, 9" cake!

        Hi! So sorry for the delay in reply - I was away from my computer all day yesterday. I usually double a 6" recipe to give an 8" cake but this has 3 layers and you said you only had 2 pans, so you could either do like a 1.5 times the recipe, or just double it and bake some off in another pan for a wee snack later, or you can just hold 1/3 of the batter back and bake two layers, then bake the last one. It should be fine to sit at room temperature for a little bit - take the cake out of the pan after it has been out of the oven for about 5 minutes, then you can run the pan under cold water to cool it down quickly so you can use it again 🙂 I hope that helps and sorry again for the delay!

    Here’s a fun fact for you: in New Zealand, TV a Here’s a fun fact for you: in New Zealand, TV a stations and radio stations don’t run ads on some public holidays. So TV on Easter was prime time to record all your fave movies on video because you didn’t have to fast forward through the ads when you were re watching them back. The sound of music and the parent trap both had “Good Friday, great movie” on them and were so good to watch because no frantic fast forwarding needed. Anyway that’s just a random thought for you. We also never really had an Easter dinner or anything growing up but it seems like it’s more popular here! I’d like to let you know that if you need a super squishy garlic butter dinner roll, there’s one on my website. Ok that’s all happy Saturday 💕

    Easter is sneaking up on us.... I gave my classic Easter is sneaking up on us.... I gave my classic hot cross bun recipe a wee bit of a refresh just in case you need a few options. This one is the one to go for if you’re making your dough by hand (the soft ones I posted recently need the mixer for sure), or you need an egg free dough (notes in the recipe for an egg free cross too). I love both but the pastry cream cross on these ones is particularly good. You can swipe to see how that gets there, or check out the recipe in my profile 💕 pop any questions you have on the blog post for me - there’s alllll sorts of notes there for you too to help you. As always I love when you leave me feedback / ratings so much. Appreciate you all 😘
