What You’ll Need

• Brownie Base: 1 cup unsalted butter, melted until it’s just glossing over, 2 cups granulated sugar, and make sure you’ve got 4 large eggs, family-sized if you can! A teaspoon of vanilla extract will warm it, plus a cup of all-purpose flour, half a cup cocoa powder for that chocolatey goodness, and a pinch—just a pinch—of salt.
• Cookie Base: Another cup of unsalted butter, this time softened, a cup of packed brown sugar, and half a cup of granulated sugar, 2 more large eggs, another teaspoon of vanilla, and—here’s the kicker—2 1/2 cups all-purpose flour. Toss in a teaspoon of baking soda, a teaspoon of salt, and 2 cups of chocolate chips, because why not?…
• Peanut Butter Frosting: Grab 1 cup of creamy peanut butter, half a cup of softened unsalted butter, 3 cups of powdered sugar—this is where the magic happens—and a bit of milk, about a quarter cup, plus another teaspoon of vanilla for that rich flavor.

Easy How-To

Making the Brownie Dough

Alright, first things first—preheat your oven to 350°F (that’s about 180°C, but who’s counting?). Line a baking tray with parchment paper so things don’t stick… nobody likes that. In a big bowl, melt the butter and chocolate together until it’s smooth, no weird lumps! Let it cool a bit, then add in your sugar, eggs, and vanilla. Mix it all up until it’s looking like… well, delicious.

Add the Dry Bits

Now for the dry ingredients! Sift together flour, cocoa powder, and salt—this just makes everything fluffier and nicer. Gradually fold that into your wet mixture, but don’t go crazy stirring; we need to keep it soft and fudgy. Just mix until it’s… well, just combined!

Bake the Brownies

Spread that rich brownie mixture into your lined tray and pop it in the oven for about 20-25 minutes. You’ll know it’s ready when you can poke it with a skewer and get a few moist crumbs on it. Let it cool completely in the tray so it doesn’t crumble into chaos when you cut it!

Whipping Up the Frosting

While cooling, go ahead and make that dreamy peanut butter frosting. In a bowl, beat together the creamy peanut butter, softened butter, powdered sugar, and a splash of vanilla. Add a bit of milk if it’s too thick—it needs to be spreadable, not a rock! Make it creamy… oh, the smell is heavenly.

Assemble Those Sandwiches

Now, slice your brownie layer into squares. Grab one, slather on that frosting like you mean it, then top it with another brownie piece. Press down gently so it sticks together. You can make them as tall as you like! Just try not to eat them all at once…

Let Them Chill

Pop your assembled sandwiches into the fridge for about 30 minutes. This helps the frosting set a bit. Once they’re chilled, slice them right through the middle for that Instagram-worthy moment (if you’re into that), and serve them up!

Good to Know

• If you have leftovers—and I mean, a miracle happens if you do—store them in an airtight container in the fridge for up to a week.
• Oven temps can be sneaky, so keep checking those brownies as they bake, you want them fudgy, not overcooked!
• Crunchy peanut butter adds a different texture if you’re feeling adventurous, or swap in almond butter for a twist…

Serving Ideas

• Serve these with a scoop of vanilla ice cream for a decadent dessert experience, or alongside a hot cup of tea or coffee—a match made in heaven!

Top Tricks

• To get perfect brownie layers, check for doneness with a toothpick early, then adjust your baking time based on what you see.

Frequently Asked Questions

Can I use a different nut butter?

Absolutely! Almond butter or even a sunflower seed butter works great if you’re not into peanuts. Just tweak it to your liking—your kitchen, your rules!

Can I freeze the cookie sandwiches?

Yes, yes, and yes! These sandwiches can hang out in your freezer for up to three months—just pop them in an airtight container…

What if the cookie batter is too dry?

If it feels dry, you can add a smidge of melted butter or an extra egg to loosen it up a bit. It happens, and it’s no biggie!

How can I make the cookies chewy?

For a chewier cookie, just bake them a tad less. Take them out when they still look a bit soft in the center, and they’ll firm up as they cool on the sheet.

Can I add chocolate chips to the cookie batter?

Definitely! Chocolate chips just take it to the next level. Plus, who says no to even more chocolate, right?
