Recipe Rundown
Magical Jumbo Cookie Series
One of my favorite series I’ve ever made is the Magical Jumbo Cookie Series. These are big, bakery-style cookies (think Levain Bakery) each inspired by a different Disney character. I even created a princess-themed eBook with them — you can check it out here! This Dumbo cookie is a little preview of what to expect from the series, and it might just be one of my favorites yet.
Why Dumbo?
When I was little, I used to watch Dumbo’s Circus on TV — have you ever seen it? It’s a little strange to look back on now, but at the time, I absolutely loved it. I haven’t watched the movie in years, but my daughter and I still ride Dumbo at Walt Disney World all the time. It’s one of those classic rides we never skip.
About the Cookie
For Dumbo’s cookie, I knew it had to have a peanut butter base (because Dumbo of course). I wanted it to feel a little like a circus treat too, so I mixed in white chocolate chips, marshmallows, and a sprinkle of crushed graham crackers. It’s soft, gooey, and completely magical — definitely one of my all-time favorite cookies.
And honestly? Even if you’ve never seen Dumbo, if you’re a peanut butter fan, you need to make this one.
FAQ
1: Why freeze the mini marshmallows first?
Freezing the marshmallows keeps them from melting too quickly while baking, helping them stay gooey inside the cookies instead of disappearing into the dough.
2: Can I skip the peanut butter center?
Yes! The peanut butter center is optional — the cookies will still be packed with peanut butter flavor from the chips.
3: How big should the cookie dough balls be?
Aim for about 5–6 ounces each — think oversized bakery-style cookies. Bigger dough balls help you get that gooey middle and chewy edge.
4: Why should I let the cookies cool overnight?
Letting the cookies rest allows the flavors to deepen and the centers to set properly. If you can’t wait overnight, give them at least a couple of hours.
5: Can I use all white chocolate chips instead of a mix?
Absolutely! You can customize the chip mix to your taste — try all white chocolate, all peanut butter, or even throw in butterscotch chips for a fun twist.
Sprinkle of Fun
Throw a Dumbo-inspired circus party right at home! Bake up a batch of Dumbo’s Peanut Butter Marshmallow Jumbo Cookies and add easy treats like caramel apples, popcorn bags, and cotton candy sticks to the table. Set up a ring toss, a hula hoop “jump through the hoop” challenge, or make a “peanut toss” game with buckets and foam peanuts. Play the original Dumbo movie (or the live-action one if you want a double feature) and hang up some streamers or colorful balloons for that circus feel.
Dumbo’s Peanut Butter Marshmallow Jumbo Cookies
Ingredients
- 1 cup (2 sticks) salted butter, cold and cubed
- 3/4 cup granulated sugar
- 3/4 cup packed light brown sugar
- 2 large eggs, cold
- 2 teaspoons vanilla extract
- 2 3/4 cups all-purpose flour
- 2 tablespoons cornstarch
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup peanut butter chips
- 1/2 cup white chocolate chips
- 1/2 cup mini marshmallows (freeze for 15 minutes before using)
- 1/2 cup crushed graham crackers or crushed peanut butter cookies
- 1/4 cup peanut butter, refrigerated for 15 minutes optional
- Flaky sea salt, for sprinking
Instructions
- Preheat the oven to 410°F (210°C). Line a couple of baking sheets with parchment paper.
- Cream butter and sugars until just combined (about 1-2 minutes). Do not overmix.
- Mix in eggs and vanilla until fully incorporated.
- Whisk together dry ingredients (flour, cornstarch, baking soda, salt) in a separate bowl and mix into the wet ingredients.
- Gently fold in peanut butter chips, white chocolate chips, mini marshmallows, and crushed graham crackers.
- Portion dough into large balls (5-6 oz each). *If you’re using the peanut butter, shape the dough around a small dollop of it. The reason for this, is that you want to stop it from melting and running outside the cookie.
- Bake for 9-12 minutes until golden but slightly underbaked in the center. Sprinkle them with sea salt while they’re warm.
- Cool for 30 minutes before transferring to a rack. Let them cool completely before serving, ideally overnight.
