ingredient notes
Full ingredient measurements and instructions can be found in the recipe card below!
- Buttermilk: This recipe needs to be made with real store-bought buttermilk (not homemade) or the crumb and texture will not be the same.
- Oil: Any flavorless oil will work for this cake! I used canola oil but vegetable oil will work as well.
- Eggs: Make sure the eggs are at room temperature before using or they won’t incorporate into the batter.
recipe instructions
Before you start: Line the bottoms of three, 6-inch cake pans with parchment paper and preheat the oven to 350 F/180 C.
Step 1: Soak the fruity pebbles in the buttermilk and set them aside.
Step 2: Cream together the unsalted butter, oil, and granulated sugar with a paddle until fluffy, about 3 minutes. Then stream the eggs, vanilla extract, and lemon extract into the mixing bowl until combined. Scrape down the bowl with a rubber spatula, then add a third of the all-purpose flour, baking powder, and salt and mix on low until just combined. Pour in half of the buttermilk, and mix until just combined. Continue alternating the dry and wet ingredients, ending with dry, mixing until just combined.
Pour the batter equally into the cake pans and bake for 26-28 minutes.
Step 3: Combine the all-purpose flour, fruity pebbles, melted butter, baking powder, and sugar until it forms balls of crumbs. Spread them out onto a lined baking tray and bake at 300 F/150 C for 15 minutes. Let the crumb cool completely before using.
Step 4: Make the buttercream. Mix the butter on medium speed until smooth and lump-free, then add the powdered sugar. Mix on low until combined, then mix on high speed until it looks white and fluffy. Add some of the cereal milk to the bowl and mix until combined. Set the frosting aside and cover until ready to use.
Step 5: When ready to assemble, use a serrated knife to level the tops of the cakes and expose the crumb. Use a pastry brush to lightly soak the top of the cake with some of the cereal milk.
Step 6: Add a thin layer of frosting to the top of the cake and spread evenly with an offset spatula.
Step 7: Sprinkle about 1/4 cup of the fruity pebble cake crumb on top of the frosting, then add the next cake layer. Continue the same process as steps 5, 6, and 7. Place the last cake layer upside down so that the bottom of the cake is now the top.
Step 8: Use the rest of the buttercream to thinly frost the rest of the cake. You can make a double batch of the frosting for a thicker layer if desired! Top the cake with more of the cake crumbs and enjoy.
expert tips for the best cake
- Use a kitchen scale: Baking with a scale is faster, easier, and overall much more accurate than cup measurements.
- Use room temperature ingredients: Using room temperature ingredients creates a smooth, fully blended batter that will result in a uniform texture and even baking.
storage & freezing
- Fridge: Store the cake whole or cut it into slices in the fridge for up to 5 days.
- Freezer: You can freeze the whole cake for up to one month in the freezer. You can also freeze the slices individually! Cut the cake into desired slices and freeze them for 10-15 minutes until firm, then wrap each one in plastic wrap and freeze until ready to eat.

- Whisk together the flour, baking powder, and salt and set it aside.

- Whisk together the eggs, vanilla, and lemon extract then stream them into the mixing bowl, mixing well until completely combined. Scrape down the bowl.
- Add a third of the dry ingredients and mix on low until almost combined then mix in half of the buttermilk. Continue alternating the dry ingredients and buttermilk, ending on dry, mixing until just combined.
- Divide the batter evenly amongst the cake pans and use an offset spatula to smooth the tops. (about 370 grams in each pan)
- Bake the cakes for about 26 minutes or until the tops bounce back when touched. Let them cool for 20 minutes on a wire cooling rack, then run a knife or offset spatula around the sides of the pan and remove each layer. Let them cool completely on the rack before frosting.
How to Make the Cereal Milk
- In a small bowl, combine the fruity pebbles and milk and set it aside. You will use it for the cake layers and the buttercream!
How to Make the Cake Crumb
- Combine the melted butter, flour, sugar, fruity pebbles, vanilla, and baking powder with a spoon until it forms round crumbs. Spread them out onto a lined baking tray. Bake the crumbs at 300 F/150 C for 15 minutes, then set them aside to cool.
How to Make the Cereal Milk Buttercream
- In a stand mixing bowl, cream the butter on medium until smooth and lump free.
- Add the powdered sugar and mix on low until combined, then increase the speed to high and mix until the buttercream is light and fluffy. Add 2 tablespoons of the cereal milk and mix until combined.
Assembly
- Use a serrated knife to cut a thin layer off the top of each cake layer to expose the crumb. Use a pastry brush to lightly brush each top with some of the cereal milk.
- Spread an even layer of some of the buttercream on the top of one cake round. Sprinkle about 1/4 cup of the cereal cake crumb on top of the frosting, then place the next cake layer on top.
- Continue layering the cake, placing the last cake layer upside down so that the top is super flat.
- Use the rest of the buttercream to frost the entire cake with a thin layer of buttercream. If you like a thicker layer of frosting, I suggest making a double batch of the buttercream!
- Finally, add more of the cereal cake crumbs on the top of the cake and enjoy!
