1-Step 1: Prepare the Caramelized Cereal Start by preheating your oven to 350°F. While the oven warms up, grab a small baking sheet and mix together 65 g of roughly crushed cereal (corn flakes work wonderfully), 56 g of melted unsalted butter, and 26 g of granulated sugar. Spread this mixture evenly on the baking sheet and pop it in the oven for 8-10 minutes. You’ll know it’s ready when the cereal turns a beautiful golden brown and your kitchen starts smelling like toasted goodness. Keep an eye on it during those last couple of minutes, as the sugar can go from caramelized to burnt pretty quickly. Once done, set the caramelized cereal aside to cool completely before incorporating it into your cookie dough.

2-Step 2: Set Up Your Baking Station Line a large baking sheet with parchment paper. This prevents sticking and makes cleanup so much easier. I always find that using parchment also helps the cookies bake more evenly and develop those lovely slightly crisp edges while staying soft in the center.

3-Step 3: Cream the Butter and Sugars In your stand mixer fitted with the paddle attachment, combine 140 g of room temperature unsalted butter with 126 g of brown sugar and 100 g of granulated sugar. Beat these together on medium speed for about 1 minute until smooth and creamy. This creaming step is important because it creates air pockets in the butter, which helps your salted egg cookies achieve that perfect texture. The mixture should look pale and fluffy when properly creamed. If you don’t have a stand mixer, a hand mixer works just as well, or you can use a sturdy wooden spoon with some elbow grease.

4-Step 4: Add Wet Ingredients Mix in 1 tsp of vanilla extract and your large room-temperature egg. Beat just until everything is well combined. Overbeating at this stage can incorporate too much air and affect the final texture of your cookies, so stop once the egg is fully incorporated and the mixture looks smooth. Using a room-temperature egg is key here. Cold eggs can cause the butter to seize up slightly, leading to an uneven dough. If you forgot to take your egg out ahead of time, simply place it in a bowl of warm (not hot) water for about 5 minutes.

5-Step 5: Combine Dry Ingredients In a separate bowl, whisk together 200 g of all-purpose flour, 3/4 tsp baking powder, 1/2 tsp baking soda, and 1/2 tsp salt. This ensures even distribution of the leavening agents and salt throughout your flour. Add this dry mixture to your wet ingredients and mix on low speed just until the flour is incorporated. You want to see no more dry flour streaks, but don’t overmix. Overmixing develops gluten and can make your egg yolk cookies tough instead of tender.

6-Step 6: Fold in the Good Stuff Now comes the fun part! Gently fold in the cooled caramelized cereal, your 4 coarsely chopped cooked salted egg yolks, and most of the 175 g of coarsely chopped white chocolate. Reserve a small handful of the white chocolate pieces to place on top of each cookie before baking.

7-Step 7: Shape Your Cookies Portion the dough into 10 balls, roughly equal in size. I like using a cookie scoop for consistency, but you can also use a spoon and your hands. Place them on your prepared baking sheet, spacing them about 2 inches apart to allow for spreading. Press a few pieces of your reserved white chocolate onto the top of each dough ball. This gives your salted egg yolk cereal cookies recipe that bakery-style appearance and ensures you get those beautiful pockets of melted chocolate in every bite.

8-Step 8: Bake and Cool Slide your baking sheet into the preheated 350°F oven and bake for 11-13 minutes. You’re looking for edges that have begun to caramelize and turn golden while the centers still look slightly underbaked. They’ll continue cooking on the hot baking sheet after you remove them from the oven. For those Instagram-worthy crinkled edges, try this professional trick: right after removing the cookies from the oven, gently tap the baking sheet on the oven rack. This settles the cookies slightly and creates those lovely textured edges. Let the cookies cool on the baking sheet for 5 minutes, then carefully transfer them to a wire rack to cool completely. This cooling time allows the centers to set properly while maintaining that soft, chewy texture we all love.
