How to make cereal cake from scratch?

  1. Bake cakes- A rainbow cake was the perfect choice.
  2. Let it cool- Until it’s room temperature.
  3. Make chocolate icing- It should be a thick but spreadable consistency.
  4. Assemble– Place one cake on cake stand, ice the top, then, place the other cake on top and then, ice the whole cake.
  5. Make cereal flowers- By dropping a spoonful of melted chocolate on a sheet of wax paper and sticking cereal in a flower formation.
  6. Let it set– This takes about 10 minutes.
  7. Stick all over cake- Press each cluster gently.

Key ingredients

  • Cake– This was a rainbow cake so that the inside is just as much fun and whimsical as the outside.
  • Frosting– Chocolate icing was the best pairing with this cake flavor.
  • Cereal– I used Trix cereal but other colorful cereals can be used too.
  • Melted chocolate- This works like “edible glue” to make the flower shape.

Variations for Chocolate Cereal Cake

Use other cereals- There are so many different shapes, sizes and colors and you can get as creative as you like with the design. Froot Loops and Fruity Pebbles would be great alternatives.

Try other frostings- Such as this Mint Frosting or this Coconut Cream Chocolate Frosting.

Try different cake flavor– Such as this Chocolate Brownie Cake or this Chocolate Coffee Cake.

Cover cake in fondant– Once the cake is smoothly iced, cover it in colored Marshmallow Fondant and then stick the flowers on it with melted chocolate.

Make a layer cake- This is a single tall cake. Bake 3 inch cakes and stack them on top of this 6 inch cake. Make sure to use dowels for support.

Add cake fillings- Such as Homemade Strawberry Jam or peanut butter or Nutella or thick ganache.

Use white chocolate- Instead of using melted semisweet chocolate to make flower clusters. You can also use colored candy melts.

Toss sprinkles- To make this cake even more colorful and fun!

Tips and Techniques

Don’t decorate a warm cake- The cake must cool completely because if you frost a warm cake, the icing will melt into a sticky mess.

Line pans with parchment paper- This makes it easier to remove cakes from the pan.

Trim edges and dome of baked cakes– This allows you to make a leveled cake that’s not tilted.

Don’t remove flower clusters too quickly from wax paper- The chocolate has to set until hard. If you remove it too quickly, the flowers will break.
