Reese’s Pieces Peanut Butter Blondies

Delicious homemade peanut butter blondies loaded with Reese's Pieces and peanut butter flavor. Recipe on

Calling all peanut butter lovers! These delicious blondies are LOADED with peanut butter butter flavor and studded with sweet Reese’s Pieces – one of my absolute favorite candies. The Reese’s Pieces add a nice crunch to these soft and chewy blondies. I love a good texture contrast in my baked goods – especially one from Reese’s Pieces.

  1. I had to post a comment here. Your very first post got one comment and now you get like abajillion a day:) I can’t believe how quickly you’ve grown! I’ve been blogging for several years and feel like I can learn so much from you! Awesome job girly, you rock!!

  2. Sally! I think even your first post is pretty darn good, although it is so impressive to see how far you’ve come in just one short year! You are seriously amazing, girl! I am so impressed and excited to continuing following you on your blog journey. Loving your blog series posts, too–I’m learning so much from you! 🙂

  3. Hi Sally – I made these this weekend, and they were fantastic! However they were a little tough/dry like I used too much flour. So I had two questions – how do you measure your flour? Sifted and measured? Or just dig the cup in? And also, is the brown sugar packed?

  4. I was so exited to make these, I’m pretty are all my measurements were correct , but the batter was really dry and crumbly. I don’t think it was supposed to be. It’s in the oven right now.. So I’m hoping they still turn out. Please let me know what your thoughts are. I only used 2 1/2 cups flour.

  5. Sally, I have never commented on your blog before, though I am an avid reader. I just wanted to let you know that you inspire me so much. I am a teenager trying to have a nice, popular blog like yours, and seeing your first post gave me hope that maybe, someday I can have a popular blog like yours with 50+ comments on each post. Thanks for being a hugeeee inspiration for bloggers everywhere!

  6. Omgossssshh I found your first post! Of course it was peanut butter- what else could it be?!? You’ve come so far now and yet still peanut butter is blinging out in your recipes! (not that I’m complaining.) I feel we might need a new blog name soon…

  7. This recipe was absolutely fantastic! I had people who don’t like sweets or peanut butter tell me that they loved it. I took these to work and people kept coming by asking me if I had any more long after they were gone. I will never eat plain Reeses Pieces ever again. Thanks for sharing! Followed the recipe as written and it was perfect.

  8. I started my food blog 5 months ago. It helps looking at successful bloggers’ first posts to see how far they’ve come for inspiration and to know that no one started at he same point they grown into now. 
    I can tell you work very hard and deserve your success! Thanks for sharing your first post. Mine is embarrassing. One day I’ll photograph it again but keep the old pic just to show my readers how far I’ve come.

    Continued good luck to you Sally!

  9. Sally!!!
    Just love your recipes and website! 
    Wanted to ask how I can adjust the ingredients to fit a 9×13 pan? 
    Thanks so much!!
