Tips for successful cookie bars:
- Don’t overmix ingredients, only mix until incorporated.
- Grease AND line your baking pan. I like to grease the bottom and corners really well and over line with a piece of parchment paper so I can easily lift out my bars.
- Allow bars to cool completely, this helps so they don’t fall apart! Let them cool if you want nice even bars.
Tools I used for this easy recipe:
- USA Pan 9×13 inch Baking 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.
- Rubber Spatula – a must for any home baker! Perfect for scrapping cookie dough out of the mixing bowl.
- Pyrex Mixing Bowl Set – I love this set of nesting bowls, perfect for home baking!
First Steps:
- Combine sugars, eggs, vanilla, and melted butter
- Whisk well to combine
- Add in dry ingredients

Why use room temperature eggs in cookies and bars?
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.
Instructions for the valentines cookie bars:
- Preheat oven to 350 degrees F. Grease or line a 9×13″ baking pan, set aside. In a small mixing bowl combine the flour, baking powder, and salt, stir to combine and set aside.
- In a large bowl combine melted butter, sugars, eggs, and vanilla. Whisk well to combine.
- Add in the dry ingredients and mix until combined. Fold in the chopped chocolate hearts and white chocolate chips, transfer into the prepared baking pan. If desired, top with extra chocolate hearts and white chocolate chips.
- Bake at 350 degrees for 28-30 minutes or until a toothpick inserted comes out clean. Remove form the oven and let cool on a wire rack, top with sprinkles and allow to cool completely before cutting.
Notes:
*Set aside whole candy hearts to press on top of unbaked bars if desired.
*Set aside a handful of chocolate chips to sprinkle on top
*Bars will be thick and fudgy, allow to cool completely, about an hour, before slicing for best results.

I made this recipe today and for me it didn’t work out. The proportions didn’t see right. It was overly buttery. Is it possible that the recipe was supposed to say 1 stick butter instead of one cup butter? Or was it simply user error? Thanks!
I’m sorry to hear that! It should be 2 sticks of butter, 1 cup – the bars are thick/fudgy. I’m curious how your bars turned out?
The batter was overly oily. So I was afraid how they would turn out after baking. I baked them much longer then the recipe instructed and the center still fell in and was quite undercooked. Probably just recipe user error. I may try again to see if I get better results. I did bake them in a glass 8×8. Not sure if that matters.
Hi, glass can conduct heat differently than metal. Glass heats slower and can get warmer around the edges/bottom. I made these again twice this weekend, once as the recipe calls for and once adding an extra 3/4 cup of flour. Both worked, the bars with extra flour were not as fudgy – more cookie like. I have adjusted the recipe slightly above.
You’re awesome. I will try the recipe again and this time I’ll make more of an effort to find my 8×8 metal pan. I saw these on TikTok and was excited to try them. Try #2 here I come!
Thanks for sharing, hope they turn out better for you this time!
