Ingredient Notes and Substitutions
- Almond meal- this recipe calls for blanched almond meal and should not be substituted.
- Egg whites- this recipe calls for large egg whites from fresh eggs. They should not be substituted for carton whites as these will not whip properly.
- Gel food coloring- any pastel color is great for these macarons. However, you should use gel or powder food coloring only because they don't have as much water content, which can result in a liquidy batter.
- Unsalted butter- it should be super soft and warm for making the buttercream.
- Fruity pebbles- you can substitute the fruity pebbles for any of your favorite cereals!
Note: Full ingredient measurements and instructions can be found in the recipe card at the bottom of this page.
Step 1: Sift the blanched almond meal and powdered sugar into a large bowl together. Any large pieces of almond meal that wont go through the sifter can be tossed.
Step 2: Whip the egg whites until they form a stiff meringue, about 10-15 minutes. Add the dry ingredients into the egg whites in thirds to not deflate the batter too much. Then use a rubber spatula to fold them together.
Step 3: Fill a piping bag fitted with a small round tip with the macaron batter and pipe it directly over the top of a silpat lined baking mat.
Step 4: Drop the tray a few times on the counter to release any air bubbles, which you can pop with a tooth pick.
Step 5: Sprinkle the tops of the macarons with crushed fruity pebbles and then allow them to rest until a skin forms on the top. Bake the macarons for 13-14 minutes and then allow them to cool completely on a wire rack before removing them from the tray.
Step 6: In a small bowl, soak the fruity pebbles in the milk. Set aside.
Step 7: Whip the butter in a mixing bowl with a paddle attachment until smooth and lump free. Add the powdered sugar in a little bit at a time and whip well until light and fluffy, then add the soaked fruity pebbles and milk. Whip on high until the buttercream is super light and fluffy.
Step 8: Fill a piping bag with the fruity pebble buttercream and pipe dollops on the bottom of the macaron shell. Sandwich the filling with the other macaron shell.
Now don't think these macarons are just for fruity pebbles, you can easily substitute any cereal instead, like these other ideas:
- Lucky Charms macarons
- Captain Crunch macarons
- Cinnamon Toast Crunch macarons
You can also fill the macaron shells with a small scoop of vanilla ice cream and then roll them in the cereal for fruity pebble macaron ice cream sandwiches!
Storage and Freezing Instructions
Once baked, French macarons should be stored in the fridge or freezer to keep them soft and fresh.
Store the baked macarons in an airtight container with a piece of parchment paper in between them if they're stacked to lock the moisture inside and keep them from staling.
The macarons can be kept out on the counter for a few hours, then they should be put in the fridge. If they sit out for too long they will lose their soft texture and get stale and crisp.
FAQ + Expert Tips
- Top the shells with the fruity pebbles before resting, if you wait too long, the shells will start to form their skin and harden and the cereal won't stick to the shells.
- Let the cereal soak in the milk long enough to get really soggy- To get the best fruity pebble flavor you want the cereal to get really soggy so we can add not just the milk but the cereal as well.
- Let the macarons mature in the fridge overnight- The most important step in making macarons is allowing them to mature in the fridge for at least 12-24 hours. This time will allow the moisture from the buttercream to seep into the shells and make them soft and chewy, as well as bring out more of the fruity pebble flavor.
