Tools I used for this easy recipe:
- KitchenAid 6 Qt. Stand Mixer – I always recommend a stand mixer as it saves time and helps to keep baked goods consistent.
- Rubber Spatula – a must for any home baker! Perfect for scrapping cookie dough out of the mixing bowl.
- USA Pan 8″ Square Pan – another USA Pan product I love! The corners of my bars and cakes never stick and I love the squared of edges this pan creates.
Second Steps:
- Whisk in peanut butter until smooth
- Fold in dry ingredients
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. Don’t have room temperature eggs? Set a few cold eggs out 20-30 minutes before you need them.
Using a stand mixer makes this recipe super easy! Grease & line baking pan for best results.

This seems like a lot of batter for an 8×8 pan, but we’ll see how it goes!
Hi, you could alternatively bake in a 9×13 pan, just alter the baking time. These bars are thick/fudgy.
Hi there, for the sugar can I just use brown sugar and does it have to be a mix of both, white and brown?
Hello! I have not tried these just using brown sugar. The taste would be the same but using all brown sugar may change the texture and color a bit.
Aren’t these just cookie bars? Blondies use all brown sugar and no white sugar, that’s what differentiates them.
You can call them what you would like!
