Oven: 170c°/150c° Fan Oven/Gas Mark 3 to 4/340f°
Instructions
To Make The Cake Layers
Begin by softening your butter to be ready for using. I like to soften butter by cutting into small cubes, (about 1cm, ⅓″), since a smaller size has a smaller surface area, that softens & comes to room temperature quicker. If you forget or are short on time, try a hack I tried for softening butter in about 12 minutes. Make sure your eggs are also at room temperature.
When the butter is soft enough, cream together with the sugar, for a few minutes until soft & spreadable and paler in colour. For a stand-mixer, use the k-paddle for this. (If using granulated sugar as an alternative, you will need to beat longer). Next beat in the eggs, one at a time, followed by the Vanilla Extract, just until incorporated.
Sieve the flour (and baking powder if using Plain/All Purpose flour), over the wet ingredients, before starting to mix in by hand. Add in the milk & then use your hand/stand-mixer to mix all together, just until all combined and no flour is visible (make sure to check the bottom of the bowl, and scrape down the sides of the bowl if needed). Don't be tempted to over-mix. Then fold in the oven-safe sprinkles by hand (see notes), in increments of 3, to ensure an even distribution and for your cake to rise nicely. Pre-heat the oven to: 170c°/150c° Fan Oven/Gas Mark 3 to 4/340f°.
You can of course prepare your cake pans/tins before making the cake batter, but I prefer to do this when the oven is heating. If your oven takes longer than 7 or 8 minutes to come to temperature, turn on sooner. You want to grease and paper line 2 or 3 8" (20cm) cake pans. I used Homemade Cake Lining Paste. This is also called Cake Gloop & works really well on bundt pans. Brush on a good layer, with upward strokes, up the sides of the pan. (See Photo 2 above). Alternatively another good option is Frylight cooking spray, that is like cake release spray, but less expensive. Failing that, butter and flour bottom and sides of the pan. Be sure to also paper line the bottoms of the tins with baking/parchment paper. See how to cut parchment for round cake tins, and use less paper. Then divide the batter into 3 - each cake layer will weigh 538g/19 oz. I only had 2 same sized pans so weighed to be exact.
Tap the tins on the counter/worktop before popping in the oven to bake for about 28-35 minutes, until golden on top & starting to come away from the sides of the tin. Check they are fully cooked by inserting a cocktail stick in the centre of the cake, which should come out clean of crumbs. If not, continue cooking for a couple more minutes and check again until done.
Place the cake pans on a cooling rack for about 5 minutes, before attempting to turn out. Place a clean folded tea-towel on top of the cooling rack (or some paper), and turn the cake pans over to release the cake. It should come out easily, but if not just run a knife around the edges of the cake and try again. Leave upside down on the rack. If re-using one of the cake pans for the 3rd cake layer, wipe clean with paper towel/kitchen paper and grease & line, before adding in the remaining third of cake batter. Pop in the oven and cook as before. (This single cake might bake a little quicker).
Meanwhile carefully start to remove the paper from the cooling cakes. If it doesn't want to come easily, leave to cool more. Once all cake layers are cool you can put the cake together, or well wrap each layer with cling film/plastic wrap until ready to use. I like to stack the cakes on top of each other and wrap again. This gives a nice flatter cake (see Photo 5 below). You can make the cake layers up to 3 days before if well wrapped and left in room temperature.
To Make The Buttercream
Beat the softened cubed butter with a hand/stand-mixer (k-paddle of a stand-mixer), until no longer in small cubes, and easy to spread. Gradually add in the icing/powdered sugar, (use a splash guard or clean towel on top) and starting on the lowest speed, beat until a nice smooth buttercream. If needed you can add a few ½ tsp milk if too thick, but this is a slightly thicker buttercream that stands up well for a 3 layer cake. See photo 4 and check my Buttercream for Beginners tutorial if you need to.
Finally add in the Vanilla Extract and your buttercream is ready to use right away. Keep well-covered in a bowl at room temperature or store in the fridge until ready to use (this can be up to 1 month1 and 2 to 3 months in the freezer2. See my buttercream tutorial for more information).
To Assemble The Cake
To assemble the cake, I always do this on the cake board or on the plate I want to serve on. (Charger plates are good for this). This saves trying to transfer it. Just cut a couple of pieces of baking/parchment paper and hold in place on top of the plate/board, apart and held in place with a tiny bit of buttercream. See Photo 5. Begin with your first layer of cake, with the bottom flat side of the cake pointing upwards. Any crack(s) in the cake when moving, just fill with some buttercream like in Photo 6 below.
Next have your piping bag filled with the prepared buttercream and fitted with a large close tipped star nozzle (see my beginners' guide for assembling and filling a piping bag tutorial). Pipe large rosettes in a border along the edge of the cake and spread a thinner layer of the buttercream in the centre. (See Photo 6). Now place the cake in the fridge for 30 - 45 minutes for the buttercream rosettes to firm up. This stops the cake layers buckling as you add more layers, and keeps better definition of the piped buttercream too.
Now gently place the second cake layer on top, again with the flat bottom side up. Repeat with another layer of buttercream and piped rosettes, before popping back in the fridge again, for another 30 minutes to set. (See Photo 7).
Place the third cake layer on top and begin by piping slightly taller rosettes, around the outside edge of this top cake layer. (See Photo 8). Then fill the centre with rosettes about the same height as you piped in-between the cake layers.
Finally, sprinkle on some of the remaining sprinkles on top of the piped buttercream, (these ones don't have to be bake-safe sprinkles), before placing in the fridge for at least 45 minutes to set. See Photo 9 &10.
Serving & Storing
Once firm, the cake will slice nicely, and serve a lot of people as it is a big cake! Store somewhere cool or in the fridge if needed. Will be fine sitting out, as long as not too hot. Store in a cake box or loosely covered container (avoid covering tightly with cling film/ plastic wrap, especially if in fridge, as it can cause condensation. Will last at last 3 days and can be frozen for up to 3 months in the freezer3 (It is recommended to wrap really well in slices - see Freezeit.co.uk for more information on freezing frosted cake).
Notes
Sugar - UK Caster Sugar is used, and Extra/Super Fine Sugar is very similar. If you have to use granulated sugar, you can either process a little to make fine sugar, or when beating with the butter, mix a few minutes longer for the larger sugar granules to break down. Flour - UK Self-raising flour is used, not to be confused with US Self-rising. For that I recommend adding 1 tsp of baking powder. If using Plain or All Purpose flour, add 4¾ tsp Baking Powder when sieving in the flour.Sprinkles - bake-safe sprinkles must be used for this cake. Any sprinkles not in the cake batter, do not need to be bake-safe. Here in the UK our sprinkles are not for the oven, and so break up and melt when in the oven, causing all the colouring to bleed and mix together. For that reason I recommend these ones that were recommended, and I have tested them, and they work really well. I purchased from Amazon for about £9, and it is larger bottle than the typical sprinkles we have, and used less than half. Look them up in Amazon - Leiber's Rainbow Sprinkles. See before recipe for more information.Vanilla Extract - Vanilla extract is always better than essence or flavouring, but very expensive, so try making Homemade Vanilla Extract.Buttercream - the buttercream for this recipe is a firmer one, with slightly different proportion of butter to sugar, that works well for piping in-between tall layer cakes. See my Buttercream Tutorialfor beginners.Piping Bag & Coupler - a star nozzle and coupler was used on the piping bag, to quickly change between the star nozzle for piping rosettes, and piping buttercream in the centre of the cake. This might seem strange but with stacking the cake layers upside down, with a very slight dome, a thinner layer of spread on buttercream in the centre area, and a border of higher, piped rosettes around the edge, makes the cake layers more level. So no need to try and cut the cake. Means slightly less piping, & leaves more butter for taller rosettes on the final top layer of cake. If you don't have a coupler, either hold back some buttercream to spread on, or pipe a little through the nozzle & then spread flat. (See Photo 6 for reference). See lesson link below for more on the star nozzle used. How To Assemble & Fill A Piping BagButtercream Top Tip - always chill after piping a buttercream filling, (for 30 - 45 minutes), before putting the 2nd layer on cake on top. This helps keep the shape and definition of the piped buttercream, and stops it buckling too much from the weight of the cake.Cake Tins/Pans - I used 2 8"/20cm cake tins/pans, to make 3 layers. 3 tins would have been better. If you don't have 8" tins, and want to make in a small sizes or bigger sized tins, check out my articles on reducing a cake recipe, or increasing a recipe , that both include all my calculations you need, as well as worked examples.For more on different ingredient names, check my Differences Between UK & US Baking Ingredients article.
