Crunchy Cornflake Cookies Recipe

This chewy cookie packs great flavor and is simple to make. The sugary, crispy goodness of these Cornflake Cookies brings a smile. Light and crisp on the outside with the extra crunch of cornflakes, yet slightly chewy inside—truly a perfect balance.

I first discovered this recipe in the Colorado Cache Cookbook a friend shared with me. At first it sounded a little unusual, but I tried it and these cornflake crispy cookies exceeded expectations. They have become one of my favorite cookie recipes—simple, comforting, and nostalgic.

The flavor and texture remind me of a classic sugar cookie. The addition of cream of tartar brings a slight tang and helps create that light, tender crumb that evokes childhood memories.

TRY THESE CORNFLAKE CRISPY COOKIES

These cornflake cookies are essentially a sugar cookie with a crunchy twist. The cornflakes add texture without overpowering the buttery, sweet dough. They are perfect for holiday cookie trays, after-school snacks, or cookie exchanges. Serve with a glass of milk for the classic experience.

Using Leftover Cornflakes

A large box of cornflakes often outlasts one recipe. This recipe is a great way to use up cereal before it goes stale. Cornflakes also work well in other recipes like fried ice cream pie, crispy oven “fried” chicken coatings, or as an add-in for old-fashioned cookies and casseroles.

INGREDIENTS NEEDED FOR CRISPY CORNFLAKE COOKIES

This recipe uses simple pantry ingredients. The quantities are listed in the recipe card below, but here are the essentials:

• Butter – unsalted, one stick (1/2 cup)
• Granulated sugar – provides sweetness and crisp edges
• Baking soda – small amount for lift
• Cream of tartar – contributes to a light, slightly chewy texture
• All-purpose flour – the base of the dough
• Cornflake cereal – adds crunch; any plain cornflake brand works
• Salt – a pinch to balance flavor

HOW TO MAKE CORNFLAKE COOKIES

Begin by preheating the oven to 350°F and lining a baking sheet with parchment paper.

Next, cream together the butter and sugar in a large bowl until light. You can use a stand mixer or a hand mixer, or do this by hand. Add baking soda, cream of tartar, flour, and a pinch of salt. Mix until combined, then gently fold in the cornflakes by hand so they stay somewhat intact for added crunch.

Then, drop tablespoon-sized portions of dough onto the prepared cookie sheet, spacing them about 2 inches apart. Bake for roughly 13 minutes, or until the edges are just beginning to turn golden brown. Watch closely toward the end of baking so the cookies don’t over-brown.

Finally, transfer the cookies to a wire rack to cool for a couple of minutes. They will crisp up further as they cool.

FAQS

Can margarine replace butter? Yes, margarine can be used in the same amount as butter. Keep in mind the texture and flavor will differ. Butter adds rich flavor and helps produce tender centers with crisp edges. Margarine typically contains more water and less fat, which can make cookies spread more and bake crisper. If choosing margarine, stick-style margarine with a higher fat content gives results closer to butter.

How long have corn flakes existed? Corn flakes were developed in the late 19th century as a flaked cereal. They became a popular breakfast cereal and are widely used in recipes that call for a light, crunchy coating or mix-in.

SUBSTITUTIONS

• Butter: Swap with margarine if needed—expect a change in texture and spread.
• Sugar: You can replace up to half the granulated sugar with light brown sugar for a slightly deeper flavor and chewier texture.
• Cornflakes: Rice cereal like Rice Krispies, or other plain cereals such as Special K or Wheaties, will also work for crunch. Frosted cereals will add extra sweetness.

TIPS AND TRICKS

• Make the dough ahead and chill up to 24 hours; bring to room temperature before scooping and baking for even results.
• Use a cookie scoop for consistent cookie size and more even baking.
• Double or triple the recipe when you need more—this is an easy small-batch recipe to scale up.
• Add 1/2 cup mini chocolate chips, butterscotch chips, chopped nuts, or coconut flakes for variation.
• Store cooled cookies in an airtight container at room temperature for 3–4 days, or freeze in layers separated by wax paper for up to three months.
