Rosanna Pansino and Her Wi-Fi Cheesecake!

by  | October 21

From cookies and brownies to cupcakes and (let’s be honest here) raw sugar packets, here at Glommable HQ we love anything sweet. So when we heard that that Rosanna Pansino, our favorite nerdy baker and creator of the wildly popular YouTube series, was writing a cookbook chock-full of deliciously geeky treats, we had to feature her on the site. Check out this recipe from Rosanna’s first cookbook, THE NERDY NUMMIES COOKBOOK (pre-order your copy now at Amazon, Barnes & Noble, or IndieBound) and let us know how it turns out (and invite us over for a slice, of course!). Rosanna, take it away!

WI-FI helps people stay connected to the internet from almost anywhere. I designed this cheesecake to look like a Wi-Fi symbol when you cut into it. Once you’ve made this recipe, connecting to the internet will be a piece of cake!


Makes one 9-inch round cheesecake


  • New York–Style Cheesecake
  • Electric blue food coloring gel
  • 9-inch springform pan
  • Decorating bag
  • #12 decorating tip


  • 1-1/2 cups cookie crumbs (graham crackers, gingersnaps, or chocolate wafers)
  • 1/4 cup sugar
  • 5 tablespoons salted butter, melted


  • 4 packages (8 ounces each) cream cheese, at room temperature
  • 3/4 cup sugar
  • 2 large eggs, lightly beaten
  • 1 teaspoon vanilla extract
  • 2 tablespoons cornstarch
  • 1 cup sour cream


1. Preheat the oven to 350°F.

2. Make the crust: In a large bowl, whisk together the cookie crumbs and sugar. Stir in the melted butter until the crumbs are evenly moistened. Press the crumb mixture onto the bottom and 2 inches up the sides of a 9-inch springform pan. Bake for 10 minutes to
set the crust. Remove from the oven to cool, but leave the oven on.

3. Make the filling: In a large bowl, with an electric mixer, beat together the cream cheese and sugar until smooth and light.

4. Beat in the eggs, vanilla, and cornstarch until just combined (do not overmix).

5. Mix in the sour cream until well blended.

6. Pour the mixture into the prepared crust and spread evenly.

7. Bake at 350°F for 45 minutes. Turn the oven off, prop the door open slightly, and let the cake sit for 1 hour.

8. Remove from the oven and place on a wire rack to cool to room temperature.

9. Cover and refrigerate until well chilled before serving. (My trick: I place a dinner plate wrapped in a clean kitchen towel on top of the springform to prevent any condensation from dripping onto the cake.)

5. Scoop the blue mixture into a decorating bag fitted with a #12 tip.

9. Cut the cheesecake into portions to resemble Wi-Fi signals . (F)


IF YOUR CHEESECAKE IS CRACKING, TRY BAKING IT in a water bath to add moisture and more gentle heat while baking. For a water bath, wrap your cheesecake pan bottom and sides with aluminum foil, then place in a larger pan with about 1 inch of water to bake.
