When we were kids we baked a lot of fun desserts with our mom, she definitely wasn’t anti-sugar. But she did have one rule … no sugary cereal in the house. So it wasn’t until we were out on our own that we even tasted Fruity Pebbles Cereal. To make up for the lost time we’ve made these yummy Fruity Pebbles Sugar Cookies with Cereal Milk Icing. We were lucky enough to take a Christina Tosi Baking class and we fell in love with her cookies. These yummy cookies are our riff on her style of adding cereal mix-ins to a cookie. Soft and chewy and crunchy, our family gave these flavorful sugar cookies a big Thumbs Up! We hope you love them as much as we do!

Expert Tips and FAQs

Cookie Dough Mixing Tips

Creaming the butter, and sugar and then mixing the eggs in is the most important part of the cookie dough mixing process. Creaming is when you fully incorporate the butter and sugar together and add some much-needed air to the dough. We recommend creaming the butter and sugar for 2 minutes at medium-high speed and then mixing the butter/sugar/eggs for another 3 minutes at the same speed. Once you add the flour, you want to mix the dough as little as possible. Mix it too much and you will get tough cookies. Mix in the flour on low speed and continue mixing ONLY until the dry ingredients are incorporated into the dough. Make sure you scrape down the sides and the bottom to make sure all the flour has gotten mixed in.

Prepping the Cookie Sheet

We always line our cookie sheets with a piece of parchment paper, it keeps the cookie from sticking to the sheet and from over-browning. You can find parchment paper either in rolls or in pre-cut sheets in most grocery stores, and we highly recommend it. Ideally, you should use at least 2 cookie sheets when baking cookies. You don’t want to add the raw cookie dough to a cookie sheet that is hot out of the oven. The dough will start baking even before you get it in the oven.

Storage/Freezing Tips

Cookies should always be stored in an airtight container.  They should be completely cooled before storing them. We usually add a layer of parchment paper between each row of cookies in our plastic container.  Cookies stored at room temperature should stay fresh for 3-4 days. You can also keep them in the refrigerator and that extends their freshness for up to a week. If you need them to last longer, you can freeze them for up to 3 months. You can pull them out of the freezer and leave them on the counter for 1 hour and they will be ready to eat.
