Why this Fudge is Best

I don’t know about you, but birthday cakes are the best. They don’t have to be elaborate, I prefer them without fondant, but I want them to be packed with flavor (and frosting).

In my ideal world, I would choose either a chocolate cake with vanilla frosting….or a funfetti cake with funfetti frosting. I mean, it’s sprinkles. Who doesn’t love sprinkles?

Today’s fudge is so easy, you’ll wonder why you haven’t tried it yet!

  • No candy thermometer needed!
  • Sets up in a few hours, but can be stored in the fridge for weeks!
  • Soft and creamy with a crunch thanks to the cookies inside!

My ideal birthday menu would consist of some homemade dinner (chicken tetrazzini please), with a side of sweet potato casserole (yes it’s an odd combination), a batch of rice krispie treats, and today’s fudge!

Tips and Tricks

  • Use the mini Nilla Wafers if you can find them. This will make cutting the fudge and not having too much “crumble” so much easier. If you can’t find the minis, I would break each cookie in half.
  • Before you start melting your butter and cream mixture, get your other ingredients ready. First, add your white chocolate and marshmallow fluff to your mixing bowl so it’s ready to melt when you add the hot cream mixture over it. Second, line your 8 inch baking dish with parchment paper. Toss a few cookies (wait, that sounds wrong) into the bottom of the dish (don’t cover the bottom, but add a few cookies).
  • GENTLY fold your remaining cookies and mini marshmallows into the fudge mixture. Do not overmix. Add a few sprinkles and quickly pour this into your prepared dish. Top it with MORE sprinkles (why not??)

Birthday Cake Fudge is a fun, festive Disney inspired treat. Packed with cookies and marshmallow, this is one easy fudge recipe you can't resist!


  • 1 bag (11 ounce) white chocolate chips
  • 1 jar (7 ounce) Marshmallow Fluff (creme)
  • 2 cups granulated sugar
  • ¾ cup unsalted butter
  • ¾ cup heavy whipping cream
  • pinch of salt
  • 1 ¼ cups Mini Nilla Wafers, divided
  • 1 cup mini marshmallows
  • ½ cup sprinkles, divided


  1. Line an 8 or 9-inch square baking dish with parchment paper. Add about half of your cookies to the bottom of the dish. Set aside.
  2. In a large electric mixing bowl, add white chocolate chips and marshmallow cream. Set aside.
  3. In a medium saucepan over medium high heat, add sugar, butter, heavy cream, and salt. Bring mixture to a boil while stirring constantly.
  4. Once boiling (a good rolling boil), allow mixture to boil for 4 full minutes (while stirring). Remove from heat.
  5. Pour hot sugar mixture over the white chocolate and marshmallow in the mixing bowl. Turn the mixer on and beat on low until smooth, about one minute.
  6. Fold in the remaining cookies, marshmallows, and half of the sprinkles. Pour into prepared baking dish.
  7. Add the remaining sprinkles on top of the fudge. Allow to set, about 3 hours.


  • Use clothespins or binder clips to hold the parchment paper in place.
  • No need to refrigerate fudge. Allow to set at room temperature. You can refrigerate to speed up the process, but allow it to come to room temperature before slicing.
  • Store fudge in airtight container at room temperature for up to one week, or store in refrigerator for up to 3 weeks.
  • See blog post for more recipe tips and tricks.
