Paris Baguette Rainbow Cake Recipes

RAINBOW CAKE!

Steps:

• Preheat your oven to 160ºc/140º fan and line three 8"/20cm springform tins with parchment paper and leave to the side for now.
• Weigh 5-6 medium eggs in their shells and get as close to 300g as possible (e.g. 312g)
• Then add 312g of butter and caster sugar to a bowl and beat until light and fluffy.
• Add in the eggs, and 312g of self raising flour and beat again until smooth.
• Split the mixture evenly into three bowls, and add three of the colours each (for example, red, yellow and orange.)
• Bake the cakes in the oven for 30 minutes (or until baked - test with a skewer).
• Once baked, leave the cakes to cool in the tin for 10 minutes before removing to a wire rack to cool fully.
• Repeat this process again and use the other three colours (for example, green, blue and purple!). Once all the cakes are baked, leave them all to cool fully.
• (You can wrap the sponges in clingfilm once they have cooled and freeze over night to make decoratin easier but this is optional!)
• Once all of your cakes are cooled, you can make the buttercream.
• Beat the room temperature unsalted butter on its own for a few minutes to soften it and make it supple.
• Gradually add the icing sugar beating very well each time until its all mixed in.
• Keep beating and add the white food colouring and vanilla extract and beat for a few minutes.
• Using a 10" cake board, add your first sponge. I start with purple as its the bottom colour.
• Add a couple tablespoons of the buttercream on to the sponge and smooth over. Repeat this with blue sponge, then green, yellow, orange and finally red at the top.
• Using a small amount of buttercream, smooth over the sides of the cakes and fill in any gaps and create a crumb coat.
• Refrigerate or freeze the cake on the board for an hour or so to chill and firm to make the next stage of decorating easier.
• Once chilled, add on lots more buttercream around the sides of the cake with a small angled spatula, and smooth over using a large metal scraper until the sides of the cake are smooth like in the photos!
• Carefully press some of the sprinkles into the bottom of the cake using the palm of your hand to create the sprinkle effect!
• Once this has been done, refrigerate again whilst you make the drip!
• Add the white chocolate and double cream to a bowl and heat in a microwave in short 10 second bursts stiring well each time.
• Once melted and combined, add the pink food colouring and mix until smooth!
• Add the pink ganache to a piping bag and carefully cut off the end and drip down the sides of the cake. The more you push over the side of the cake with the piping bag, the further it will drip!
• Add the leftover buttercream to a piping bag with your favourite piping tip and pipe swirls of buttercream onto the top of the cake (like I have done in the photos)
• Finally sprinkle on some etra sprinkles and leave the cake to set in the fridge fully.
• In the hot weather I store the cake in the fridge until it has been portioned.

RAINBOW CAKE

Steps:

• NOTE: It is SUPER IMPORTANT that all the room temperature ingredients listed above are room temperature and measured by weight so that the ingredients mix and incorporate correctly. Heat oven to 335º F/168º C
• Prepare six ( 8"x2") cake pans with cake goop and place a round piece of parchment paper in the bottom of the pan for easy removal of the cake
• Combine 8 oz of the buttermilk and the oil together and set aside.
• Combine the remaining buttermilk, egg whites, and vanilla together, whisk to break up the eggs and set aside.
• Combine flour, sugar, baking powder, baking soda and salt in the bowl of a stand mixer with the paddle attachment. Mix 10 seconds to combine.
• Add your softened butter to the dry ingredients and mix on low until mixture resembles coarse sand (about 30 seconds).
• Add in your milk/oil mixture and let mix until dry ingredients are moistened and then bump up to med (setting 4 on my KitchenAid) and let mix for 2 full minutes to develop the cake's structure. If you don't let your cake mix on this step your cake could collapse.
• Scrape your bowl and then reduce speed to low. Add in your egg white/milk mixture in three batches, letting the batter mix for 15 seconds between additions. Scrape down the sides again to make sure everything has incorporated.
• Divide your batter into 6 bowls. Weigh 15 ounces of batter for each bowl.
• Color each bowl with your Electric food colors. 1/2 tsp for pink for the pink layer, 1/4 tsp yellow plus 1/4 tsp orange for orange layer, 1/2 tsp yellow for yellow layer, 1/4 tsp yellow plus 1/2 tsp green for green layer, 1/2 tsp blue for blue layer, 1/4 tsp pink and 1/2 tsp purple for the purple layer.
• Bake your layers for 20-24 minutes or until the edges JUST start pulling away from the cake pan. Do not under-bake or the middle of the cake will collapse.
• IMMEDIATELY TAP PAN FIRMLY on countertop once to release the steam from the cake. This stops the cake from shrinking.
• Let cakes cool for 10 minutes inside the pan before flipping them out. The cake will shrink a bit and that is normal. Freeze your cake layers 30-60 minutes before trimming your cakes. Frost and fill with buttercream frosting.
• After your buttercream is smooth, place the cake back into the fridge for 15 minutes before you apply your drip.
• Wait for your drip to set before painting with gold paint. Finish the cake with buttercream rosettes and more sprinkles.

EASY SIX-LAYER RAINBOW CAKE

Steps:

• Preheat the oven to 400 degrees F (200 degrees C). Grease six 9-inch round cake pans and dust with flour.
• Sift together the flour, baking powder, and baking soda.
• Beat 3/4 cup plus 2 tablespoons butter, milk, sugar, egg whites, and vanilla extract in a large bowl with an electric mixer until smooth. Stir in flour mixture and mix until just combined.
• Divide cake batter evenly between 6 bowls. Mix in different food coloring to each bowl, creating 6 different colored batters. Start with just 1 to 2 drops of food coloring in each bowl, then mix; you can always add more.
• Bake each cake in the preheated oven, until a toothpick inserted in the center comes out clean, 15 to 20 minutes. Set aside to cool.
• Beat cream in a chilled glass or metal bowl with an electric mixer until stiff peaks form. Stir together confectioners' sugar and mascarpone cheese in a separate bowl, then fold gently into the whipped cream until smooth.
• Spread frosting on each layer of cooled cake, placing one on top of the other. Cover the top and sides with the remaining frosting. Refrigerate for 2 hours before serving.
