Reese's Pieces Peanut Buttery Brownies

Reese’s Pieces Peanut Buttery Brownies

February 26, 2009


By now you probably know that I’m extremely obsessive about peanut butter. I almost took a picture of my kitchen cabinet to show you how serious my obsession is, but then I worried someone would have me committed. Yes, I’ve heard about all the horrible salmonella cases, but I just can’t give peanut butter up (and it’s all on sale at the grocery store too!). I just make sure I’m careful not to eat anything on the recall list, but otherwise, I don’t find it necessary to give up my joy in life (fine, it’s not my only joy in life, but it is a big one).

Anyway, it’s pretty hard to give up peanut butter when people keep posting peanut butter recipes all over the Internet. Sara posted a recipe from The Life and Times of Grumpy’s Honeybunch for “Da Bombe Brownies Peanut Butter Style” and I was so in love, I made them the next day. I re-named them to:

Reese’s Pieces Peanut Buttery Brownies:

  • 1 1/2 C mini peanut butter cups, chopped (I would use more next time though)
  • 1 C butter, melted (2 sticks)
  • 3 C sugar
  • 1.5 T vanilla extract
  • 4 eggs
  • 1 1/2 C all-purpose flour
  • 1 C unsweetened cocoa powder
  • 1 t salt
  • 1/2 C Reese’s pieces

First I chopped up all my mini peanut butter cups. The recipe called for 1 1/2 cups, but I will definitely use more next time. The brownies weren’t quite peanut buttery enough for my likes. I might even throw a dash of real peanut butter into the batter just to make them even more delicious.

Combine the melted butter, sugar, and vanilla in a large bowl. One at a time, mix in your 4 eggs until fully combined.

Then in a separate bowl, whisk together your flour, cocoa powder, and salt.
Slowly pour the dry ingredients mixture into the wet mixture and mix until it’s well combined. Then add in your peanut butter cups!

Pour the mixture into a greased 9×13 baking dish.

Then pour your Reese’s Pieces over the top. The recipe called for mini Reese’s Pieces, but I couldn’t find them (and didn’t even know they existed…I guess they’re probably like mini M&Ms?), so I just used the regular size.

Bake at 350 degrees for about 35 minutes.

And then dig in! Make sure you don’t bake the brownies too long as it’s easy for them to get dry (they’re super thick). That’s another reason I think the addition of some creamy peanut butter is an amazing idea.

If you feel sick after eating these…I’m going to take a guess and say it’s because you ate way too many of them and that it doesn’t have anything to do with salmonella. But it’s OK; I don’t blame you for eating the whole batch of them. They’re that good.

    Tastes pretty good upon first contact, although it needs a lot more bakin time than 30 minutes. At least 45 minutes. We had very very fudgy and drippy brownies after 30 minutes.

  14. Girl says:

    OMG! I am so looking forward to baking these! I am going to bake them as a surprise for my boyfriend. lol. Hopefully, they will turn out as yummy as the pictures! I have a tendency of overcooking sweets. So wish me luck!!

    Reese’s Pieces are my husband’s favorite, so I made these for his birthday a couple of days ago. SO GOOD! I never bake or cook, so the step by step instructions and pictures were very helpful. Thank you!!

    Just made these for my evening master’s class – the guys in there requested something with Reese’s Pieces. These looked fabulous, so I tried them. Will let you know what the verdict was. I think they will love them!

    These are just what I am looking for to make for nephew’s birthday, he loves peanut butter and chocolate! Thanks for the great idea of putting the reese’s pieces on the top! I might suggest that you check out my daughter-in-law-to-be’s (I love saying that) blog, it’s! Happy Baking!

    whoa! these are amazing. i made two batches in 3 days because my family devoured the first one. they are rich and sweet, like eating fudge! if you have an oven like mine, that typically cooks really fast, you may want to put them in for about 30 minutes. the first batch i did for 35. they were still really good but the edges came out a little dark. 30 minutes was perfect for my taste.

  20. Christina says:

    Truly delicious. <3

  21. Kimberly says:

    These are so yummy! My fiancee asks me to make them all the time. The only problem I had was getting the middle to cook evenly with the edges. Sometimes they are just too gooey for my liking. But hey… some people like gooey.

  22. Tyler says:

    These look soo good, I’m gonna have to try them. And if you’re having trouble getting the middle to cook evenly with the edges, you don’t have the right pan. This is what you need:

    Mini Reese’s are just what they’re called. Miniature peanut butter cups. They come in small plastic bags. And they don’t have wrappers on them. Really yummy.
