Strawberry Pop-Tart Cake

I contribute footage of a few cakes each month to the Food Network, to share across their social channels. This strawberry Pop-Tart-inspired cake was definitely my favorite one this month, and it was so fun I wanted to share the recipe.

The best part of this cake? The adorable mini strawberry Pop-Tarts used to decorate the base of the cake. The good news is that they’re just as simple to make as they are cute.

They’re made using store bought pie crusts, strawberry jam, an egg wash, and some colorful buttercream and sprinkles. If you wanted to fully make them from scratch, you totally can! But since cakes are already such a labor of love, I like to not get too crazy with the decorations.

This cake is made with my tried and true layer cake and buttercream recipe, plus some strawberry jam and pink gel food coloring, for good measure. The recipes used include:

  • 1 batch of my layer cake recipe (used to bake 4, 7-inch cake layers) + pink gel food coloring to create swirled layers
  • 1.5 batches of my american buttercream
  • 1 jar of your favorite strawberry jam (for both the mini Pop-Tarts filling and cake filling)
  • 1 package of ready-made pie crust + 1 egg (to create mini Pop-Tarts)

Begin by making the cake layers and buttercream, as directed in the above recipes. The layers will take a bit of time to bake and cool, so I recommend making them first (or even a day in advance).

Next, begin to prepare the mini Pop-Tarts. Preheat the oven to 350 degrees Fahrenheit. Roll out one of the pie crusts. use a ruler and knife to score the dough to create rectangles that are 1 inch by 1.25 inches.

adding lines to pastry dough

Put about 1/2 a cup of strawberry jam into a piping bag, and cut a small opening (less than 1 cm). Carefully pipe a thin line of filling into the center of each rectangle.

While you may be tempted to add a ton of filling to each little Pop-Tart, do be warned that it will make the crimping process much more challenging, and that the extra filling will likely ooze out the sides of the Pop-Tarts as they bake. A few of mine were overfilled, and they definitely weren’t a pretty picture coming out of the oven (don’t say I didn’t warn you :P)

Next, unroll the second pie crust, and place on top of the jam lined pie crust. Carefully use your ruler to remark the rectangles (you can see the jam through the pie crust, and use it as a guide). Use a pastry cutter and ruler to cut out the rectangles.

cutting mini poptarts

Carefully lift each Pop-Tart (the pieces will slide a bit due to the filling), and crimp the sides using a fork. Also poke a few holes on top of each one, to help them rise and allow air to escape as they bake.

I had a mini fork on hand (long story, but it’s from making little mermaid cupcakes ages ago…), which worked perfectly for this! if you don’t have one, use the smallest fork you have.

crimped all poptarts

Transfer the Pop-Tarts onto a parchment paper lined baking sheet.

Beat together one egg and 1 tbsp of milk, and use a pastry brush to paint a thin layer of egg wash onto each Pop-Tart. Bake in the oven for 15-17 minutes, or until golden brown.

I was convinced these would bake up much fast, but it took some time for them to become golden brown, and baked through. Slide the parchment paper onto a cooling rack, and allow the Pop-Tarts to cool (at least 30 minutes).

Once they fully cooled, pipe buttercream onto each Pop-Tart, and top with sprinkles of your choice.

I colored a tiny but of my buttercream light and hot pink, and piped the different colors onto my Pop-Tarts. I also chose to use hot pink sanding sugar as my sprinkles.

Once the Pop-tarts are ready, it’s time to assemble the cake. Smooth a thin layer of buttercream on top of each layer. Pipe a ring of vanilla buttercream around the edge of the layer to create a frosting dam, then spread a layer of strawberry jam inside the vanilla frosting.

adding jam between cake layers

Repeat this process with all remaining cake layers. Cover the cake in a thin layer of vanilla frosting (crumb coat) to trap any run-away crumbs. Chill the cake in the freezer or fridge for about 5 minutes, until the buttercream is firm to the touch.

Next, add a thicker, second layer of vanilla buttercream. Use a bench scraper to smooth the sides of the cake. You can see a full tutorial on how to frost a cake with smooth sides here. Use a small offset spatula to smooth the top of the cake.

Pipe a bit of buttercream onto the back of each Pop-tart, then gently press it against the base of the cake. Repeat this process, alternating the colored Pop-Tarts, until the entire base is covered.

adding poptarts to base of cake

Color the remaining buttercream pink using gel food coloring, and pipe a boarder around the top of the cake using your favorite frosting tip (I used a Wilton 1M).

If desired, add a pink sprinkle blend to the top of the cake, around the boarder. I love using Neon Yolk sprinkle blends! They make the cutest blends, and use them on my cakes whenever I can.

Then it’s time to cut into the cake and try it! I am a sucker for anything with strawberry jam, so I loved this cake. I also could not stop eating the leftover Pop-Tarts! They were addicting.

This cake feeds between 16-20 people, so be sure you have lots of family or friends over (or in my case, coworkers!) to help eat it 🙂

  1. Hi chels, would amy filling work in general to add filling in between amy cake layer? Jam, preserves, or even make own filling?

    1. depends on how long it’ll be sitting until you eat it! I usually leave it out if I plan to eat it within a few hours, or will refrigerate it if I don’t plan to eat it anytime soon!

Let me know what you think!
