Directions how to make a rainbow cake
Step 1: Turn the oven on, set the temperature at 170C. Use 8-inch square cake tin, cut and line the baking paper (parchment paper) at the bottom, then use cooking spray the bottom and around the edges.
Step 2: In the mixing bowl, place the liquid first: water, eggs, oil, then put the cake mix finally on top of that. Use a hand mixer or stand mixer, start at 30 seconds on slow speed, scrape down the mixing bowl then increase the speed to medium for 2 minutes.
Step 3: Tip all the cake mixture to the ready cake-tins. Then bake for about 18-20 minutes (make sure the oven came to the right temperature already). Check the cake by touching the top, if it springs back well means it cooked, otherwise place back to the oven for another 2-3mins. Or can check with a skewer, the cake should be ready of the skewer comes out clean. Then we can leave it in a side to cool down and prepare for colorful buttercream frosting.
Step 4: whip a batch of buttercream frosting, see how to make buttercream frosting. Divide the frosting into 7 parts by using another 6 containers or mixing bowl. Then I use 6 shades color from gel paste Ameri color. Add 1-2 drops of each Ameri color to 6 containers, then use a hand whisk to whip up till you reach the desired outcome.
