Cereal Macarons with Cereal Milk Frosting

Cereal Macarons with Cereal Milk Frosting 3Cereal and I have a love/hate relationship. I love how there are endless flavors and textures, how each cereal turns plain milk into a unique drink, and how you can eat it for pretty much any meal or snack (and even when you run out of milk, you can eat it plain, kind of like teeny tiny cookies).

It’s rare for me to have the “recommended serving”. I once took out a measuring cup and measured exactly one serving. Dude, it’s the size of my fist and I have small fists. 2) I hate soggy cereal. I think there is nothing worse than fully saturated cereal. It gets all mushy and some even start deteriorating into the milk. Don’t ask me to do something once that milk hits the bowl, because unless it’s a real emergency I’m taking the five minutes to eat it.

The cereal milk from this recipe tastes like the cereal milk you would get from Frosted Corn Flakes. (I got the inspiration from Momofuku Milk Bar’s cereal milk soft serve.) I suppose you could try using a different cereal (sans the toasting) and you would technically get the flavor that cereal’s milk.

The Lucky Charms batch smelled especially good in the oven. I think it was the marshmallow bits baking and yes, they were magically delicious.

Cereal Macarons with Cereal Milk Frosting

212 g. almond meal
212 g. powdered sugar
172 g. egg whites, divided to 82 g. and 90 g (aged, if possible)
236 g. sugar
158 g. water
cereal of your choice, crushed (I bought the multipack of mini bags to have a variety.)
cereal milk frosting (recipe below)


  1. Line two baking sheets with parchment paper or silicone mats.
  2. In the bowl of a food processor, add the almond meal and powdered sugar and pulse until thoroughly combined.
  3. Sift the mixture over a large mixing bowl, throwing out the lumps as they appear.  Add 82 g. of the egg whites and stir until you get a thick mixture.
  4. In a small pot attached with a candy thermometer, combine the sugar and water over medium heat and boil until the syrup reaches 200˚F.
  5. Once the syrup reaches 200˚F, start whipping the remaining 90 g. in the bowl of your stand mixer with the whisk attachment on medium speed until soft peaks are reached.
  6. Once the syrup reaches 248 ˚F, remove the pot off the burner and slowly pour the syrup down the side of the mixing bowl with the egg whites on medium speed.
  7. Once the egg whites are fully incorporated, increase the speed to medium high until egg whites form glossy, stiff peaks.
  8. Mix a ⅓ of the egg white mix to the almond mixture and stir together until the batter is slightly lighter and less pasty.  From then on, fold in ⅓ of the egg white mixture at a time until the mixture “flows like magma”.  The mixture should be smooth and run thick ribbons off the spatula.
  9. With a pastry bag fitted with a ½ in. plain tip, pipe 1¼ – 1½ in. rounds.
  10. The piped batter may have peaks but should smooth away in a minute or two.
  11. On half of the macaron shells, sprinkle on desired crushed cereal.
  12. Let the batter stand until the tops of the macarons are dry to the touch, about 30 minutes to 1 hour.
  13. Preheat the oven to 325-350˚F.  If your oven tends to run hot go for 325˚F, if not then 350˚F.
  14. Lower the heat to from 350˚F to 300˚F. (If starting from 325˚F, lower to 275˚F.)
  15. Bake 10-12 minutes, until the feet are formed and the tops are smooth.  The macaron shell is done when you slightly wiggle it and it starts to come off of the parchment paper / silicone mat.
  16. Remove pan from oven and reheat oven to higher temperature for 10 minutes before baking the next tray, lowering the temperature when you start baking it.
  17. Pipe a dollop of cereal milk frosting on the plain macaron shell.
  18. Top it with crushed cereal macaron, flattening it slightly to push the frosting to the outer edge.
  19. *This step is optional but I prefer to age my macarons. To do so, place assembled macarons in an airtight container and refrigerate overnight. The next day, the macaron shells will have softened slightly and in my opinion, more delicious.

Cereal Milk Frosting

1½ c. cereal milk (recipe below)
1/4 c. flour
½ tsp. kosher salt
8 oz. (2 sticks) unsalted butter, room temperature
¾ c. sugar
½ tsp. vanilla extract


  1. In a small pot over medium heat, whisk milk, salt and flour until combined.
  2. Continuously whisk mixture until thickened to a pudding like consistency.
  3. Once thickened, strain through a mesh strainer into a bowl with a spatula to remove lumps.
  4. Place a piece of plastic wrap on top of the flour mixture (to prevent skin from forming) and put bowl into the fridge until fully cool.
  5. In a mixer bowl fitted with the whisk attachment, mix the sugar and butter on high speed until fluffy and pale about, 5-10 minutes.
  6. Add the chilled flour mixture and continue to whip on high speed until the sugar is completely dissolved and the mixture is no longer gritty, about 5-10 minutes.
  7. Add the vanilla extract and mix until combined.

Cereal Milk


3 ½ c. Corn Flakes cereal
4 c. whole milk, cold


  1. Preheat oven to 300˚F.
  2. On a sheet pan lined with parchment paper, toast cereal for 5-7 minutes, until slightly deeper in color.
  3. Cool toasted cereal.
  4. In a large bowl, mix cereal and milk and steep for 30 minutes, until cereal is soggy.
  5. Strain mixture through a fine mesh strainer. (Do not force mixture through mesh strainer. The resulting milk will be starchy and thicker than what you started with.)
