- Rubber Spatula โ a must for any home baker! Perfect for scrapping cookie dough out of the mixing bowl.
- USA Pan 8″ Square Pan โ another USA Pan product I love! The corners of my bars and cakes never stick and I love the squared edges this pan creates.
Use a whisk or electric mixer to combine melted butter and sugars until smooth. One pro to melted butter, mixing can be done by hand.

Why use room temperature eggs in cookies and blondies?
Room temperature eggs mix together a lot easier than cold eggs, resulting in lighter, fluffier baked goods! Room temperature eggs also whip up a lot better which makes them important to use when making meringue or items that call for a lot of eggs like, angel food cake. Donโt have room temperature eggs? Set a few cold eggs out 20-30 minutes before you need them.
Press into a greased and lined 8″x8″ baking dish. If desired top with extra M&M’s or chocolate chips.
Tips for successful cookie bars each time:
- Grease and line baking dish – greasing the bottom and corners well ensure none of the cookies break off when removing them from the pan. Lining with parchment paper adds an extra level of security it make it super easy to lift these out of the pan to slice.
- Allow to cool completely before slicing – this ensures clean edges when slicing the bars
Instructions for these easy cookie bars:
- Preheat oven to 350 degrees F. Grease or line an 8 x 8 baking pan, set aside. In a small mixing bowl combine the flour, baking powder, and salt, stir to combine and set aside.
- In the bowl of a hand or stand mixer fitted with a paddle attachment or by hand, mix the butter and sugars until light and fluffy, 3-4 minutes. Add in the eggs, one at a time and the vanilla. Scrap down the sides of the bowl.
- Slowly add in the dry ingredients and mix until combined. Fold in the chocolate chips and M&M’s, transfer into the prepared baking pan. If desired, top with extra M&M’s before baking.
- Bake at 350 degrees for 30-35 minutes or until a toothpick inserted comes out clean. Remove form the oven and let cool on a wire rack, sprinkle with flaky salt and allow to cool before cutting.
