Peanut Butter Cookie Dough Brownies

These easy Peanut Butter Cookie Dough Brownies have been made into adorable Halloween treats with a peanut butter cup spider on top!

Yes, Halloween Week continues!!  So far Kristan and I have made Oreo Spider Cupcakes, Cauldron Cupcakes, Vampire Bat Cake & Ghost Cupcake Cones.


Today is actually the final day of original treats, but get ready for a fun round up post on Friday and a link party where you guys can link up all your favorite Halloween treat ideas!!



Anyhow, back to me.

And these brownies.


They’re my favorite fudgy brownie with peanut butter cookie dough (egg-free of course) smeared all over the top.

Can it get any better?


Ok, yes, it can, actually.

You can cute-it-up and make a quick little spider from peanut butter cups and put that on top.

Delicious & Halloweeny.

I know.

Peanut Butter Cookie Dough BrowniesWhen they are baked and cooled make your egg free peanut butter cookie dough.

Spread that all over the brownies.

I grabbed 2 different sizes of peanut butter cups, the miniature and itty bitty ones.

On the smallest ones I piped on eyes with black frosting.  You could also use the black gel, or even black candy melts.

Those spiders are too cute!! How did I not know that Chocolate Twizzlers were a thing? I’m questioning my whole life right now.

Averie @ Averie Cooks

Oh they look so good! I did a guest post on another site about 6 mos ago and made brownies that look similar to these but I called it peanut butter-buttercream. I am in love with your concept of spreadable PB cookie dough! SO thick and rich! I love all things PB 🙂

Meagan @ A Zesty Bite

These are seriously the cutest brownies EVER!


Those look so cool! I love how you used the peanut butter dough as frosting!


They are so cute and oh my gosh, those brownies and the peanut butter cookie dough frosting look incredible! Seriously, you are dessert genius and you know how to make the cute as ever too!


These sound delicious! Can’t wait to try the recipe! Question: Do they need to be refrigerated, (because of the peanut butter cookie dough)?
