Finally, we form our cookies. Line your baking sheets with parchment paper. Working quickly while the mixture is still pliable, drop rounded tablespoonfuls (I use a medium cookie scoop) onto the prepared sheets. If the mixture starts to harden in the pot, you can gently re-warm it over the lowest heat for 30 seconds. If you’re adding sprinkles or holiday M&Ms, press a few onto the top of each warm cookie immediately after scooping. For a drizzle, let the cookies set completely, then melt your candy melts and zig-zag it over the tops. Let the cookies cool and set at room temperature for at least 30 minutes until firm.
Pro Tips for Best Results
Use a true heavy-bottomed pot. I tried making this in a thinner, cheaper pot once, and the bottom scorched before the sugar had even fully dissolved. A Dutch oven or heavy saucepan distributes heat evenly, protecting your precious caramel from burning and giving you that perfect golden color.
Have all your ingredients measured and ready to go before you turn on the stove. This is a mise en place moment. Once the caramel starts boiling, you don’t have a spare second to measure peanut butter or find the vanilla. Having the cereal and peanuts in bowls right next to the stove is a game-changer for a smooth, panic-free process.
If your cookies are spreading too much or not holding a nice mound shape, your mixture may have been a tad too warm when you scooped it. Let it cool in the pot for just 2-3 minutes before scooping. This brief rest allows it to thicken slightly, giving you perfectly formed, domed cookies.
Common Mistakes to Avoid
The number one mistake is not stirring constantly during the initial melting and boiling phase. I got distracted answering a text for maybe 45 seconds, and I ended up with a thin layer of burnt sugar on the bottom of my pot that gave the whole batch a slightly bitter taste. Keep that spoon moving from start to finish—it’s your insurance policy.(See the next page below to continue…)
