I was on a mission to clear out the pantry, which is how I wound up making Corn Flakes Macaroons. I'd intended to make Frosted Flakes Chocolate Chip Cookies, but the Corn Flakes and coconut needed attention.

What a sweet surprise! The Corn Flakes Macaroons were excellent. The texture is chewy and satisfying, the flavor is coconut-forward with a hint of nuttiness, and the Corn Flakes lend a subtle crunch that makes them feel a bit retro in the best way possible. They’re like a cross between a classic coconut macaroon and one of those no-bake church cookbook specials, only with actual egg whites and a proper bake.
What They Taste Like
These are definitely sweet tooth territory. If you like classic macaroons, you’ll love them. The coconut and chopped toasted pecans add richness and depth, and the Corn Flakes? They’re the wildcard that brings it all together with a gentle crunch and a nostalgic vibe.
The egg whites provide the structure, whipped lightly with cream of tartar until foamy. Then the sugar is mixed in, and finally, all the goodies—coconut, pecans, and cereal—are folded in. A quick bake in the oven turns them into golden, crispy-edged, chewy-centered treats.
Pantry-Clearing Perks
Best of all, these macaroons helped me use up a full box of Corn Flakes without resorting to a casserole or another bowl of cereal. I’d call that a win.
Sorry this recipe doesn't have an exact yield. I'll add it next time I bake these. Also, you can definitely scale down the recipe if you only have 1 or 2 egg whites or perhaps just a small amount of cereal or coconut.
Corn Flakes Macaroons
4 large egg whites
¼ teaspoon (1 ml) cream of tartar
1 teaspoon (5 ml) vanilla
1 ⅓ cups (260 grams) granulated sugar
1 cup (120 grams) chopped pecans (I toasted mine)
1 cup (90 grams) shredded coconut
3 cups (130 grams) corn flakes, crushed after measuring
Preheat oven to 325 degrees F. Line a couple of cookie sheets with parchment.
Beat the egg whites until they are white and foamy, then add cream of tartar and beat until stiff peaks form. Beat in vanilla. Gradually beat in sugar until mixture is stiff and glossy.
Fold in pecans, coconut and corn flakes.
Drop by rounded tablespoons, about 3 inches apart, onto the parchment paper lined cookie sheets. Bake 15 minutes or until lightly browned

Thank you so much! I've been making these macaroons for the past two festive seasons and there was always something wrong with the batter. It worked out this time! I dropped the macaroons into tiny cupcakes linings to make it more personalised.Thanks, now I'm going to have a great Eid ul-Fitr.

I love the look of these cookies. I need to invest in some corn flakes, huh? These cookies have me sorely tempted right now.

Whenever I see egg whites, no flour and butter, I instantly think--healthy! 😉

Macaroons? Meringues? I'm so confused!
