What Makes a Milk Chocolate Cake Great?

I?ve sure you?ve tried dozens if not hundreds of chocolate cakes in your life. So, what makes a chocolate cake great?

For starters, a chocolate cake must be spongy but a bit compact. You want the bread to be moist. You also want lots of flavour and not just brown-coloured bread. You must feel the chocolate in every bite, and not just in the frosting.?

Talking about frostings, a good frosting makes the cake. Store-bought, instant frostings are nice, but they?re rarely amazing. You must make yours for scratch.

The last thing to consider is the quality of the chocolate. It does make the difference. Lily O?Brien?s is amongst the best chocolate online Ireland chocolatiers use for projects like this one.?

What do You Need to Make a Milk Chocolate Cake?

For this recipe, we?re using relatively few ingredients. You?ll need unsalted butter for the cake, both for the batter and to grease the tin. You?ll also need golden caster sugar, granulated sugar made with beets or unrefined sugar. The recipe also calls for eggs, cocoa powder, self-rising flour and a splash of milk.?

The buttercream frosting is special too. Here?s where we?re using the premium chocolate ? Lily O?Brien?s Mega Milk Chocolate along with unsalted butter and icing sugar. The best part? The frosting is super easy to put together.

How to Make Lily O?Brien?s Mega Milk Chocolate Cake

Although you?ll find the complete recipe for Lily O?Brien?s Mega Milk Chocolate Cake, here?s a quick rundown of what we?ll be doing.

The first step is preheating the oven and greasing the cake tins. Then it?s time to cream the butter with the sugar. In another bowl, we?re combining the dry ingredients: the cocoa powder and the flour. Once we combine the butter mixture with the flour mixture, the eggs come in, and you get yourself a sweet, chocolate-scented batter.

Then we?re baking the cakes, which gives us enough time to prepare the buttermilk frosting. Assembling the cake is the fun part. Things might get a bit messy, but you want to use all the frosting ? with these things, the more, the better!

Tips for the Perfect Chocolate Cake?

  • This recipe calls for two 18-cm sandwich tins because we want a thick frosting layer in the middle, but if you?re confident in your serrated knife skills and have only one regular cake tin, you can cut the cake in half for similar results.
  • Let the cake cool down before adding the frosting, it?s still pretty much butter, and you don?t want it to melt while applying!
  • Store the finished cake in the fridge before serving; it will stiffen up the buttercream a bit and give it a nice chill.?
  • Source your premium chocolate online Ireland delivered through Lily O?Brien?s. It?s just fantastic chocolate!

Variations and Substitutions

  • This chocolate cake is absolutely delicious, but you can still make it yours with some easy substitutions.?
  • For starters, you can always add a teaspoon of instant espresso to the batter while adding the cocoa powder for a nice mocha flavour. You can also add coffee to the buttercream.
  • Decorate the cake with chocolate shavings, crushed chocolate cookies or chocolate chips. The more chocolate, the better.?
  • Strawberries are pretty garnishes, too and will add some contrast and freshness to the creaminess in the chocolate throughout the cake.
  • Why settle with a classic chocolate sponge cake when you can take it to the next level? Your friends and family will certainly appreciate the effort! Let?s check out the recipe and make some chocolate cake.?

  1. Heat oven to 190C/170C fan/gas 5. Grease with butter and line two 18-cm sandwich tins with baking parchment.
  2. Using an electric mixer, beat the unsalted butter and golden caster sugar together in a bowl until creamy and light in colour. Then add 1 egg while still mixing.
