Simple and Easy Flourless Chocolate Cake

I am super excited to share my simple and easy flourless chocolate cake recipe with you. This gorgeous flourless chocolate peanut butter cake is grain-free, gluten-free, and totally delicious. Dense and so chocolatey with notes of yummy peanut butter! It’ll be ready before you know it!
My favourite thing about this recipe…
I mean, where do I start? I’m obsessed with chocolate and this packs a punch of flavour! Really hits those chocolate cravings. I also love the addition of peanut butter in this recipe. It’s obviously a flavour match made in heaven. But it’s in the cake, and it’s in the frosting. Speaking of frosting!
I love the peanut butter stripes too! So classic, but really effective and easy to achieve! You can watch me do it in the video below or click here to watch!
This is magic!
Before I made this recipe, I had no idea that adding peanut butter to cooking chocolate would make it so velvety smooth and add a dimension of flavour that is magic! I don’t know about you, but sometimes when you add butter to the chocolate and try to melt the two ingredients together, it can seize. I just find that really frustrating. But adding peanut butter stopped that from happening.
What does this simple and easy flourless chocolate cake taste like?
Chocolate, chocolate, CHOCOLATE! So fudgy, it has lots of eggs but doesn’t taste eggy. The texture is smooth and moist. It kind of reminds me of a really simple tea cake. Like, something you can serve with tea or coffee.
What you need to make this cake
Cake
Dark chocolate – Use dark chocolate for this recipe. It will give you a strong chocolate flavour without being overly sweet. And make sure it’s cooking chocolate for best results. I use the Nestle baking melts.
Unsalted Butter – You could use salted butter here but just keep in mind the peanut butter will give you some salt in the recipe.
Peanut Butter – I used regular smooth peanut butter. You can use crunchy if you like for added texture and crunch.
Eggs – Regular large-sized eggs are good here. Whisking them before you add them to the warm chocolate mixture will ensure that there’s no risk of them cooking in the chocolate
Caster sugar – this will dissolve in the mixture easily.
Cocoa powder – use unsweetened cocoa powder and use a really good quality cocoa powder too. It makes all the difference.
Ganache
Dark Chocolate, butter and peanut butter – Make sure you use dark chocolate in this recipe if you don’t want the ganache to be overly sweet. You can use salted butter if you like, but there’s already salt in the peanut butter I used.

Tips for making simple and easy Flourless Chocolate Cake
• This recipe is really easy. The only tip I have for you guys is to use a springform pan when baking. It’ll make taking it out of the pan so much easier than not using one.
• Make sure the peanut butter is warm when piping it on top of the ganache. Make sure the ganache is still thin enough too so that you can have the best results when swirling.

Can this be made sugar free?
Unfortunately I’m not sure as I haven’t tried it with no sugar.
To make the ganache it says add cream, but I can’t see how much to use in the ingredients list? Sorry if I’m kept being blind !
Hi Steph, apologies about the missing ingredient. Have gone in and aded it! N x
