Amirah Kassem’s Los Angeles home is a perfect personification of her personality. It’s filled with color and life, which is what her recipes are known for.

“I’m a firm believer in (the) birthday lifestyle. I talk about it all the time,” she explained to Jessica Holmes. “You wake up, wear your favorite clothes, eat your favorite food and hang out with your favorite people. Same with your house. You wake up to it every day, why not make it the thing that makes you the happiest ever?”

She credits that spirit to growing up in Mexico.

“The streets are colorful, the houses are different colors, the food is so vibrant. Mexico reminds me of a celebration and that’s where I grew up.”

No matter the holiday, the self-taught baker will celebrate it.

Amirah explained that’s what inspired her famous explosion cakes.

The colorful cake consists of multiple layers and when you cut into it, a slow flow of colorful sprinkles spills out giving a major festive feel to any celebration.

To purchase one of her famous cakes, head to the Flour Shop website.

Frosting

  • 8 ounces unsalted butter, at room temperature 
  • 16 ounces cream cheese, cold 
  • 1 tablespoon vanilla extract 
  • 32ounces powdered sugar 

Cake 

  • 2¼ cups all-purpose flour 
  • 1 tablespoon baking powder 
  • ¼ teaspoon table salt 
  • ¾ cup unsalted butter, at room temperature 
  • 1½ cups granulated white sugar 
  • 3 large eggs 
  • 1 tablespoon vanilla extract 
  • 1⅓ cups milk 
  • Food coloring 
  • Nonstick cooking spray

Preparation

FOR THE FROSTING:

Use an electric mixer on medium speed to blend the butter until it is smooth. Add the cream cheese and blend it together until there are no lumps. Then add the vanilla. Stop the mixer and use a spatula to push down anything sticking to the sides of the bowl, making sure it’s all mixed in from the sides and everything is smooth.

Mix in the powdered sugar a little bit at a time at the lowest speed — otherwise, it will fly everywhere! Use the spatula to push down anything sticking to the sides of the bowl, making sure it’s all mixed in from the sides and everything is smooth.

FOR THE CAKE: 

1. Preheat your oven to 350°F and put the oven rack in the middle of the oven (if you are using a convection oven, set it to 325°F).

2. Combine the flour, baking powder, and salt in a large bowl and whisk until they are really mixed together. You have to mix all the dry ingredients together first, so that there are no clumps in your batter, which will create white spots. Set aside.

3. In a separate bowl, use an electric mixer on medium speed to blend the butter and sugar together, until they become fluffy. Make sure to scrape the sides of the bowl with a spatula so it’s all mixed in from the sides.

4. Add the eggs, one at a time, to the butter-sugar mixture, with the mixer on medium speed. Again, make sure to scrape the sides of the bowl.

5. Add the vanilla to the milk and set it aside.

6. Mix about 1/3 of your dry ingredients into the butter-sugar-egg mixture, then blend in half of the milk, always mixing on medium speed.

7. Mix in the second third of the dry ingredients, then the remaining milk mixture.

8. Stop the mixer for a few seconds and use a spatula to push down anything sticking to the sides of the bowl as you go, then mix in the last of the flour mixture. Make sure it’s all mixed in from the sides and everything is smooth. You don’t want any lumps, but don’t overmix it — stop the mixer as soon as the batter is smooth.

9. Divide the batter evenly into six portions. They don’t have to be exactly identical, but you want them to be close: You can use any small bowls that are all the same size: Just slowly pour the batter into each of the bowls a little at a time until they are all at the same height (it’s about 1 cup of batter per bowl).

10. Color the batter individually in rainbow colors: We use purple, blue, green, yellow, orange, and pink for our six-layer cakes. Start with a tiny drop of food coloring, stir it in completely, then add more until it is your desired color (the baked cake will come out pretty close to what you see — the outside will be a little brown, but that gets covered with frosting).

11. Spray six 6-inch round baking pans with cooking spray, then pour the colored batter into the greased pans.

12. Bake the cakes two at a time for 8 minutes without opening the oven door. Then rotate each pan so the front faces the back. Bake for another 8 minutes, or until a toothpick comes out clean when you insert it into the middle of the cake (cakes are very sensitive. The less you open your oven, the better your cake will come out! I don’t know exactly why, but I know it).

13. Let the cakes cool in the pans for 5-10 minutes (when they’re warm, they’re really fragile, and that’s when they tend to break.) Then flip them over onto a baking sheet or cooling rack and let them cool completely before you frost them.

Directions for Assembly

1. Once your cakes are baked and completely cool, lay them out with the tops facing up.

2. Use a 2-inch (5-cm) round cookie cutter to cut the center out of every cake but the top one. Never cut a hole in your top layer of cake! In this particular case, the top is the pink layer, but you can choose whichever color you want your top to be.

TIP: Some of the cake might stay on the ring, so wipe it in between each cut so you don’t transfer one cake color to the others, and you get a nice, clean center after you cut it open. Just be very, very careful to try to get the center every time, or else your layers won’t line up when you stack them all together. I like to cut them from above, because when you look at it from the side, you get a slightly different perspective.

3. Before you assemble your cake, you’ll need a base to build it on. You can buy disposable round cake-decorating boards, or you can use a plate, a cake stand, or a flat platter—whatever you use, just make sure the base is a little bigger than your cake. My rule of thumb is that the base should be about 2 inches bigger than the cake pan.

4. You start to build a six-layer cake by putting a small ring of frosting directly on top of the board in roughly the same shape as the cake ring. This is so that the cake really sticks to the base and isn’t sliding around while you’re working. I always frost cake layers with a piping bag, so it is easy to draw a ring.

5. Put the first layer of cake directly on top of the frosting. In this case, the bottom layer is purple.

6. Cover the top of the cake with an even layer of frosting. Using a piping bag, make sure to squeeze on the same amount of frosting for every layer: You just add on the same number of rings every time. I usually make three thick rings around the top of each cake, leaving a little room around the hole: The secret trick is to start by making the first ring around the hole, then moving out. You don’t want to get frosting in the hole, or your sprinkles explosion will stick to the frosting.

7. Add the second layer of cake. Eyeball it from the top after you do, to make sure the holes line up. It’s easier to adjust as you go, rather than to fix a tilting six-layer cake at the end. Add another layer of frosting and repeat until you reach layer 5

8. Now, pour the sprinkles down into the center of the hole! A measuring cup with a spout works perfectly. You’ll need about 1 ¾ cups (1 pound/455 g) of sprinkles to fill this cake. Stop and pat down the sprinkles to the height of the cake/frosting.

9. Now add the sixth and final layer of the rainbow!

10. Flip it upside-down first, so you have a flat surface to frost on the top of the cake. This is my secret way to make a straight cake, rather than trimming off any cake..

11. Apply a crumb coat and refrigerate

12. After the crumb coat is in place, cover the cake in a final layer of frosting. Of course, if you are making this to share right away and your cake doesn’t need a few minutes of chilling time, you can simply cover the cake in frosting in just one step. Either way, the final coat on this cake doesn’t have to be too thick, because we’re going to cover the cake in sprinkles. Our second layer of frosting is really for the sprinkles, so they’ll stick.

13. Cup hands and scoop up a few sprinkles, and then start moving hands up along the side of the cake, working from the bottom to the top. Drop the sprinkles against the cake as you go, and eventually they start to stick—just work your way around and around the cake until everything is covered.

14. Once you’ve sprinkled it, you can—you should—enjoy it right away, but you can store it in the fridge for a few hours or overnight.

Note on Assembly: To cover the outside of 1 rainbow cake or 3 mini cakes in sprinkles, you will need: ½ pound sprinkles = 225 g = about 1 cup / To fill the inside of 1 rainbow cake or 3 mini cakes with mixed sprinkles, you will need: 1 pound mixed sprinkles = 455 g = about 1 ¾ cups (keep in mind, these don’t have to be sprinkles; it can just be 1 ¾ cups of candy!)
