What You Need
Just a handful of pantry and fridge staple ingredients are needed to make this easy caramel mud cake.
Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.
For The Cake
- butter - either salted or unsalted butter is fine to use in this recipe
- brown sugar - for that moist caramel sweetness. You can use either regular brown sugar or dark brown sugar. Dark brown sugar will give you a richer caramel flavour than regular brown sugar. Note: I generally use regular brown sugar as I love the light caramel flavour it gives the cake
- milk - I recommend using full cream milk in this recipe
- white chocolate - use a good quality white baking chocolate such as Cadburys White Melts
- plain flour - also known as all purpose flour
- self raising flour - also known as self-rising flour, this is a blend of plain flour (all-purpose flour) and a raising agent. You can make your own by adding 2 teaspoon baking powder to every cup of plain flour.
- vanilla extract - or vanilla bean paste or vanilla essence
- eggs - use large eggs (60 gm) and have your eggs at room temperature before preparing the cake batter
- pinch of salt - this perfectly balances the sweetness of the cake
For The Frosting
- butter - either salted or unsalted butter is fine to use in this recipe
- brown sugar - again, either regular brown sugar or dark brown sugar can be used in this recipe
- milk - I recommend using full cream milk, rather than light or skim, for a fuller flavoured result
- soft icing sugar mixture - use soft icing mixture, rather than pure icing sugar as you want the frosting to be soft, creamy and luscious, rather than set firm.
Step By Step Instructions
I just love the sweet wafting smells coming from the kitchen when this cake is baking in the oven!
Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.
Step 1 - Melt
Preheat your oven to 150 degrees celsius (fan forced) and grease and line both the base and sides of a 20cm round cake tin.
Place the butter, brown sugar, milk and white chocolate melts in a bowl and heat in the microwave on 50% power (or on a stove top), stirring every 30 seconds for about 5 minutes. Allow the mixture to cool slightly.
Step 2 - Mix
Sift over both the plain and self raising flour, add the vanilla extract, the eggs and salt.
Mix to combine all ingredients.
Step 3 - Bake
Pour the mixture into your cake tin and bake for 60 minutes, and then allow the cake to cool before transferring to a wire rack or plate.
Step 4 - Make The Caramel Frosting
Melt the butter in a microwave safe bowl on 50% power. Stir in the brown sugar and milk, then microwave for two to three 30 second bursts.
Allow the mixture to cool slightly.
Sift the icing sugar over the wet ingredients and mix well together with a whisk.
If your frosting is too runny, add a little more sifted icing sugar and mix through.
Remove the cooled caramel mud cake from the baking tin and spread the frosting thickly over the top.
Expert Tips and FAQ's
While some mud cake recipes use sweetened condensed milk or golden syrup to get their caramel flavour, my recipe uses the classic combination of brown sugar and white chocolate melts which combine to create a smooth, sweet and creamy caramel flavour. Brown sugar and white chocolate give mud cakes the BEST rich caramel flavour!
Absolutely! Simply divide the mixture into 2-3 smaller tins and reduce the baking time. Ensure you make extra frosting to sandwich between the layers.
If you notice that the mud cake is browning too much while cooking, loosely place a sheet of foil over the top and continue cooking until the cake is ready.
Being a dense and rich sweet cake, servings only need to be small. This cake serves 16 people.
This caramel mud cake is best stored in an airtight container at room temperature for up to a week. Do not store the mud cake in the fridge as it will dry out. Mud cake stays deliciously moist for days, making it perfect for preparing ahead of time.
You can freeze this caramel mud cake frosted or unfrosted. Simply wrap in plastic wrap, then foil, and freeze the cooled cake for up to 3 months. Allow to come to room temperature before consuming.

can this be turned into cupcakes?

Sure! But reduce the cooking time (and note that they'll be dense - not fluffy like cupcakes!)
