Tell me about this chocolate mud cake?

I have been keeping this recipe a secret for so long, naughty I know. However, I am ready to share and let everyone enjoy this recipe as much as I do. This cake is so rich and decadent, you’ll feel like you’re eating a slice of heaven. But don’t take my word for it, try it yourself and see what I mean.

What does this chocolate mud cake taste like?

This chocolate mud cake is not for the faint of heart. It has a dense and moist texture, a deep chocolate flavor, and a thick layer of ganache on top. It’s like eating a giant truffle, but better. You’ll need a glass of milk or a cup of coffee to wash it down, trust me.

Tips to make the perfect chocolate mud cake?

  • Use good quality chocolate. The chocolate is the star of this cake, so don’t skimp on it. Use dark chocolate around 60% cocoa solids for the best flavour and texture.
  • Don’t overmix the batter. Just stir until everything is combined, then pour it into the pan. Overmixing will make the cake tough and dry.
  • Don’t overbake the cake. The cake is done when a toothpick inserted in the center comes out with moist crumbs, not clean. The cake will continue to cook as it cools, so don’t worry if it looks underdone.
  • Let the cake cool completely before adding the ganache. The ganache is simply melted chocolate and cream, and it will set as it cools. If you add it to a warm cake, it will slide off and make a mess.
  • Enjoy every bite. This cake is meant to be savoured, not devoured. Cut yourself a small slice and enjoy it slowly. You’ll be glad you did.

It’s much more accurate to bake with weights of ingredients. Get a scale, $10 or less on Amazon, Walmart, most grocery stores, etc. Such a better way. I became a much more consistent baker when I made the switch.

Buy a scale, the measurements are far more accurate.

There’s no errors for air gaps and compaction.

Salted Caramel 'Matilda' Cake - Ems Foodie Fix August 22, 2023 - 5:47 pm

[…] First of all, the cake is amazing. It was super moist and fudgy, chocolatey but not too sweet and smothered in creamy salted caramel buttercream icing. It’s like the cake in the movie Matilda, but with a caramel buttercream instead of a chocolate ganache. (Which I have also made, you can check it out here) […]

Just tried this! It took ages and ages to bake (I made it in 6-inch pans and the inside was straight raw for 50 minutes) and so the outside dried out a bit. I also ended up not bothering with the ganache and just did the buttercream inside and out. However, even with a dry outside and no ganache it was very good! Any suggestions for next try?

Its like you read my mind! You seem to know a lot about this, like you wrote the book in it or something. I think that you can do with a few pics to drive the message home a little bit, but other than that, this is great blog. A fantastic read. I will definitely be back.
