Peanut Butter Lover’s Cookie Cake

Peanut Butter Lover's Cookie Cake

Time to whoop it up, my friends. My birthday approaches!

When it comes to my birthday, I still feel like a little kid. I want presents, parties, and many celebrations. Sometimes that means I’m setting myself up. Let’s face it: I’m a mom of three and nobody has thrown me a party since I was 25. That was a loooooong time ago. But still, I hold out hope!

One thing I’ve learned to do is bake my own birthday treat. A few years ago, I baked this cookie cake for the first time. It was my favorite cookie cake ever, but my photo skills weren’t so great back then. Plus, I wanted to see if I could make the whole thing GF and a little easier. Done and done!

Now that I’m off the hook for jury duty (I didn’t get selected, but I did make it into a courtroom, so that’s always fun), I’m full steam ahead on getting ready for the school year ahead. That means a lot of organizing, cleaning, and decision-making.

When I changed schools earlier this summer, I left a very beautiful school building behind in exchange for one with a lot more history and age. My new work home is a lot older, but it’s kept up nicely and I’ve been feeling at home here.

The thing is, I’ve been getting this reaction from some people about my change of venue that is less than desired. People tend to set a lot of store by new and sparkly things. Hey, how can I blame them? New is usually very nice. But no matter how nice a space is, a school especially, the end result is what everyone makes of it.

Students make schools come alive, not awe-inspiring entryways or corporate-looking office spaces. This is a school, and it looks like one. Personally, I find that comforting.

Okay, end rant. Can I talk about this cookie cake now?

Peanut Butter Lover's Cookie Cake

It’s chewy in the center and crispy at the edges, just like my favorite cookies are. There’s a layer of hot fudge that glues the peanut butter cups (both chopped up snack-sized and miniatures) to the top. And there are more chopped PB cups in the actual cookie.

Hey, it’s about to be my birthday. I want to do it up, and that means lots of peanut butter lover’s cookie cake for me. And if anyone wants to throw me a crazy wild party, just name the time and the venue. I’ll be there!


Peanut Butter Lover’s Cookie Cake


Cookie Cake
1 egg
3/4 cup peanut butter
1/2 cup unsalted butter, softened
1/2 cup firmly packed light brown sugar
1/4 cup sugar
1 teaspoon vanilla
1 and 1/3 cups GF oat flour
1/2 teaspoon baking soda
1/2 teaspoon salt
8 snack-sized Reese's, chopped in quarters
12 Reese's miniatures, chopped in half
hot fudge
8 snack-sized Reese's, chopped in quarters
12 Reese's miniatures, chopped in half


  1. Preheat the oven to 350. Coat a 9-inch springform pan with cooking spray. Set aside.
  2. In the bowl of a stand mixer, beat the eggs, butter, peanut butter, vanilla, brown sugar and sugar until creamy.
  3. Add the dry ingredients and mix until just combined. Fold in the chopped peanut butter cups.
  4. Spread the batter evenly into the prepared pan. Bake for 25-30 minutes. Cool completely.
  5. When the cookie is cool, remove the sides of the springform pan.
  6. Heat the hot fudge for 30 seconds in the microwave. Spread a thin layer over the top of the cookie.
  7. Pile the peanut butter cups on top of the fudge layer, pressing down lightly to make sure they stick.
  8. If desired, pipe hot fudge over the top with a small round tip.
  9. Cut into wedges and serve!




I fulfill many roles in life: wife, mother, teacher, everlasting learner. This site is dedicated to one role that expresses my creativity in ways that I find consistently challenging and rewarding: baker. Inventing new ways to enhance food, especially if that food involves chocolate or peanut butter (or both!), is a passion of mine. I look forward to sharing my ideas with you.

      I can never complain about a birthday cake I bake myself!

  2. Alice @ Hip Foodie Mom

    Mir, happy early birthday!!!! I love how you just put it out there: “I want presents, parties, and many celebrations.” hahah! ok, regarding your new school. . i’m so happy for you! When we moved here to Wisconsin, we were districted to go to the “brand new school”, it’s closer to our house, but when we moved here, it was completely full so we had no choice but to go to another elementary school in the area. Older, a little run down, whatever. People were like, you need to complain! you need to say something! you can’t send your kids to THAT school. Well, THAT school ended up being wonderful, with great teachers and staff and has more diversity than the other new, shiny school (with 99.9% white kids). So, I support you! the building doesn’t matter. it’s what happens inside that does. Looking back, everything happens for a reason. . you are at this school now for a reason. . I hope you have a fabulous school year and BIRTHDAY! love this cookie cake!

      Alice, I LOVE that you didn’t complain about the school your kids attend and that you saw all the benefits of their having a diverse experience. I’ve found that teachers tend to be amazing in schools regardless of the newness, and it’s clear you got a good deal. If only all parents were as cool as you. I’m so glad you get it!

    Haaaaappy Happppppy HAPPY early birthday, Mir! I’d totally throw you a party if we were neighbors, but you’d still have to make your own cake, because my cake would not be anywhere CLOSE to this fabulous! Now this is one hellova cookie cake! Peanut butter lovers rejoice!! This looks dangerously delicious girlfriend, and absolutely THE way to celebrate a birthday! Serious drool happening on this side of the computer screen!
    Side note- I’m glad you find your new school cozy! Sparkly and new is great and all, but you are right, it is what you make of it. And with a teacher like you at that school, I predict GREAT things!! Cheers!

    Happy Birthday, MIR! And a fabulous new school year in your new position at your new school! That is a lot of new! Without a doubt, this is a CELEBRATION cake! Thank you for making it gluten free! This will now be my go to special occasion dessert when my gf daughter is joining us. She is going to love this. Actually, I just decided we need this cake tomorrow. She went back to teaching last week (!) and the kidlets started today. A back to school celebration is called for!

      Thanks, Wendy! It’s so easy to make this GF because oat flour is the BEST. I hope it works for your daughter!

    Happy, happy birthday, Ms about-to-be-birthday-girl! What a spectacular cookie cake – Mir, if I baked this for my birthday, there’s no way am sharing – just saying! 🙂
    Glad you get to enjoy the rest of the summer before school starts back outside of a courtroom. I couldn’t agree more with you new and sparkly isn’t always the best! And a school is way more than a new sparkly building! My daughter moved into a new school during 5th grade (rezoning) – a brand new sparkly building and she so missed her old school – except for the fact that her favorite teacher and a couple of her friends transferred over too. Good luck to your new chapter in your new -to-you school!
    And, happy birthday again!

      I didn’t want to share, either, Shashi. Thanks so much! I’m glad your daughter got the sparkly school, but the old ones are nice too!
