Peanut Butter Brookies

Let me introduce you to these magical Peanut Butter Brookies! They are a mashup of brownies and cookies, blessed by the gods of peanut butter. Imagine biting into the fudgy goodness of a brownie, paired with the chewiness of a cookie, and then BOOM — an unapologetic smack of peanut butter hits you. Honestly, if you haven’t jumped on this train yet, it’s time. Save a spot on your dessert table ’cause these are going to be your new favorite guest.
So, a little background scoop: when my husband first had a bite of these bad boys, he gave me that look. You know, the wide-eyed, ‘can-I-have-this-every-day’ look. Even the kids, who pretend not to like their food touching, are all about these brookies. They’ve secured a top spot in our snack rotation, right between popcorn marathons and Tuesday’s taco night. Suffice to say, we’re obsessed!
Why You’ll Love This Peanut Butter Brookies
- They’re the hybrid we all need—brownie + cookie = happy me.
- Perfectly messy for when you’re craving something delightfully indulgent.
- That crunchy edge meets gooey center, making it sort of magical.
- Peanut butter makes everything better, let’s be real!
How to Make It
Grab your apron and let’s dive into the chaotic fun! First things first, get your oven preheating to 350°F because nobody likes waiting for that. Now, if you’re like me and constantly lose spoons in the chaotic drawer, dig them out, we’ll need ‘em. Start with the butter — melt it down but don’t you dare let it burn. Molten butter is no friend. Once that’s looking good, whisk in some sugar until your arm needs a break. Beat in those eggs one at a time like you’re in some kitchen drama on TV. Feeling like a pro yet?
Mix all the dry stuff separately, then let it rain over the wet mixture. Fold like a crazy origami project. Here’s the best part: drop in some choco chips and dollops of peanut butter. Honestly? Sometimes I eyeball it and things get crazy, but we’re all friends here.
Get that dough into a pan, let it spread like peanut butter on toast. Pop it in the oven for about 25 minutes and maybe pace around or do some squats, your call. Take them out when your heart tells you it’s time or when the edges just scream ‘eat me’.
Ingredient Notes
– Peanut Butter: Let it be the unsweetened kind for the perfect salty-sweet hit. Trust me on this one.
– Brown Sugar: The deeper, molasses-y kind is my fave. Not that your regular sugar won’t do the job. It totally will.
– Choco Chips: Use the good stuff or whatever’s in the pantry. I have a stash that saves the day!

Tips & Mistakes
Storage Tips
Oh, the leftovers — if there are any. Pop these brookies in an airtight container and stash them on the counter or in the fridge, wherever you’ve got space that day. Word to the wise: straight-from-the-fridge brookies hit differently (read: amazing) with morning coffee or tea. So if breakfast starts to look a bit beige, these will jazz it up!
Variations and Substitutions
If life hands you no brown sugar, use white and pretend it’s all okay. Swapped the flour for a gluten-free one once — no one noticed a thing. If you feel wild, try almond butter instead of peanut. Got no choco chips? Chop up that chocolate stash you hid from the kids. All is fair in love and baking!
