Gluten Free White Chocolate Mud Cake

Oh look, cake!

Gluten free white chocolate mud cake for cake decorating ~ Sweetness & Bite Ok if you’ve been following along, you shouldn’t be surprised. I promised gluten free cake recipes, and I generally follow through. Unless I’m tired and having a bad week. In which case you just have to wait a little longer. Anyway, cake. This cake. Gluten free white chocolate mud cake. Short sentences much? Gluten free white chocolate mud cake for cake decorating ~ Sweetness & Bite I used to be a chocolate girl. Usually the darker and richer the better. But in the last few years I have discovered a new-found respect for the lighter flavours of white chocolate and vanilla. This mud cake is a delicious combination of the two, smooth white chocolate flavour with a hint of vanilla in a moist and dense cake. The recipe is based on the popular Citrus Mud Cake recipe from When I started decorating cakes and baking mud cakes, it took me a while to settle on a white chocolate mud cake I was happy with. There are several popular recipes floating around the cake world, but this is the one that worked best for me, so it made sense to adapt this one to make it work gluten free. And boy, does it work… Gluten free white chocolate mud cake slice The key to this cake is to use a good quality white chocolate. One that actually contains cocoa butter, rather than a compound chocolate that uses oil instead of cocoa butter. ‘Cause white chocolate is already walking a fine line to be classed as chocolate, and compound chocolate is really just vanilla flavoured sugary fat. Have I convinced you? Gluten free white chocolate mud cake Whittaker's white chocolate Just like the dark chocolate mud cake this is an easy melt-and-mix cake. The milk, butter, white chocolate and sugar get melted… Gluten free white chocolate mud cake wet ingredients And then the vanilla, dry ingredients and eggs get mixed in. Gluten free white chocolate mud cake batter Easy. I didn’t adjust the batter amount at all, so this makes a very tall (approx 4” high) seven inch round cake. The reason I didn’t want to make a shorter cake is that white chocolate mud cakes get a rather brown crust. Even with baking strips, (and I used baking strips with twice the usual thickness of wet paper towels) you can see that the crust is still a lot darker than the rest of the cake. And coz I’m all about cake looking and tasting equally good, this means I like to trim off both the top and bottom crusts of the cake. So I kept the full sized recipe to make sure I had the height to compensate for my compulsive trimming habit. If you’re not like me, then you can scale down the recipe (or use an 8″ tin instead). To make the slices look prettier, and to give enough room for ganache on the sides of the cake, I trim off the darker edges of the cake as well. To make it easier I’ve made these templates from thin plastic cutting boards- I just trace around a cake board and then cut out the circle approx. 1cm/ ½” inside the line. Then I just place the template on each cake layer and use a small serrated knife to trim them. Gluten free white chocolate cake layers I made this a plain white chocolate cake obviously, but you can totally add back in the citrus zest from the original recipe for a lovely fruity cake. You can either use all three zests (lemon, lime and orange) or pick one for a single fruity flavour cake. White chocolate ganache is the perfect filling for this cake, and once again it’s important to use a quality chocolate. Kiwi readers will be able to tell I love Whittaker’s chocolate in all shapes and forms. And I also like it in moustache tea cups, but that’s kinda beside the point. Whittaker's white chocolate in a teacup Good quality chocolate buttons are also a good choice, because really, who actually enjoys chopping up all that chocolate (my girly hands sure don’t!) Gluten free white chocolate mud cake, chocolate buttons This cake is not quite as dense as the dark chocolate version, but it is still suitable for most decorating uses, including a bit of light carving. I wouldn’t go making a life-sized cake version of your pet alpaca out of it, but with some chilling and the use of ganache you could make most shapes out of it. You can use the CakeOmeter or the CakeOmeter app for iPhone/iPad to adjust the recipe for the tin size you want.

Gluten Free White Chocolate Mud Cake

Makes: One 7 inch round, approximately 4 inch high cake.

A moist, dense cake with delicate white chocolate and vanilla flavours. Suitable for covering in fondant, tiered cakes, lightly carved cakes, and decorating using the three day timeline.


  • 420g gluten free flour*
  • 2 teaspoons baking powder (check that it is gluten free)
  • 1 teaspoon Xanthan gum
  • 350ml milk
  • 350g butter, cut into cubes
  • 180g white chocolate, chopped
  • 400g caster sugar
  • 2 teaspoons vanilla extract
  • 4 eggs


Preheat oven to 160° Celsius. Line the base and sides of a 7” round (at least 3” high) cake pan and make a baking strip and foil lid. If your oven gets quite hot from the bottom element, place a heavy baking sheet on the rack below the one the cake will go on.

In a medium bowl, sift together the flour, baking powder and xanthan gum. Whisk to combine well.

In a large, heavy based saucepan, heat the milk and butter over a medium low heat, stirring occasionally with a wire whisk until the butter melts. Add in the white chocolate, and stir until the chocolate has melted. Add in the sugar and whisk until the sugar has completely dissolved (this could take several minutes). Remove from the heat.

The liquid mixture now needs to cool until you can comfortably hold your finger in it. You can either transfer the mixture to a large heatproof bowl to cool it faster, or you can leave it in the pot and wait a bit longer for it to cool.

When cool, add the dry ingredients in three additions. Mix with the whisk, but use a folding rather than whipping motion to avoid air bubbles.

Whisk the eggs together with a fork and add to the batter, mixing again with the whisk. Leave the batter to sit for a minute to allow bubbles to come to the surface.

Pour the batter into the prepared pan and bang it on the bench to remove any large air bubbles. Place the foil lid over the top and bake for 2.5 – 3 hours. To test if the cake is done, use a thin skewer. When the skewer comes out clean, insert a thin bladed knife into the middle of the cake. When that comes out clean or with only a few crumbs attached, the cake is done. If you have an instant read probe thermometer, the centre of the cake should be at least 99°C.

Allow the cake to cool for half an hour, then cover the top with foil, securing around the edge of the pan. Leave the cake in the pan overnight to cool completely and firm up.


*I used 200g tapioca flour, 170g brown rice flour and 50g potato starch.

Remember that if you use different flours than I have, your results may vary from mine. Check out my gluten free cake post for more information.

To fill and cover a cake this size with white chocolate ganache (four layers of cake/three layers of ganache filling) you will need 1.6kgs of ganache (1.2kg white chocolate to 400g cream.)

    Do you double your flour ratio and then use what’s required for the cake? The ingredient list says 420 g but your blend is 330 g. Thank you! Looking forward to trying this out.

      Oh goodness, no that’s a typo! My apologies. That’s what I get for twiddling with a recipe and having too many sets of notes, I copied the individual flour amounts from the wrong notes. I have fixed it now :)

      Thanks so much for letting me know! I’m usually very meticulous at checking my recipes.

      PS: I saw the butter cake you posted on your Facebook page the other day, looked delish! xx

    Hey, this cake looks amazing but I was wondering if it’s ok to freeze it? would it ruin it for shaping?
    Thanks for positing such comprehensive recipes btw, certainly makes things easier!

      Hi Shani, you can definitely freeze it. Let it cool in the tin as it says in the recipe, then wrap it really well in plastic wrap, pop it in an airtight container and freeze it. When you want to use it, make sure you leave it to thaw at room temperature, still in the container and the plastic wrap, until it has come back to room temperature. This way it won’t get soggy from the condensation as it thaws :)

    Wow, I’m surprised this requires 2.5-3 hours to bake! I have baked many gluten free cakes, in two or three pans (to make 2 or 3 layer cakes) for the typical hour and they are done.

    This recipe sounds amazing though! So, I took the time to convert all of your measurements to US cups, and if I were to make mini cupcakes of this recipe I believe I should half? everything for 40 mini cupcakes.

      Hi Kim! It’s not the fact that this is a gluten free cake that means it takes a long time to bake. All Australian-style mud cakes that are typically used for cake decorating are baked for a long time at a low temperature. This ensures that they are baked right through to the middle before the outside dries out, and makes sure they stay lovely and moist. This recipe also makes a much higher cake than many traditional recipes. But you can certainly bake it in several smaller pans and it will take less time. I sometimes split it into two pans, but I prefer to do it in one, it is more moist and I only have to cut off and discard (or eat!) one top crust when I level it. Then I split it into four layers before filling it.

      I’m afraid I’m not sure how many cupcakes it would make, but I suspect half the recipe should be enough for 40 mini cupcakes. I’d love to know how you get on :)

    Hi just wondering if you use pre-mix/store bought flour can you leave out the gum? This cake looks awesome. Thainks

      Hi Trudi, yep if the mix already has a gum ingredient added, then you can leave it out of the recipe :)
