Behind the Recipe
When I was a kid my Dad would bring home boxes of the different Tastykakes® from the local grocery store. The first box I would open (READ: tear into) was their Peanut Butter Tandy Kakes.
With that memory still fresh in my brain after all these years, I knew I wanted to share a homemade version of this classic with you all, which could, dare I say, rival the brand's version.
If you've never heard of the Tastykakes brand before, they are a Philly-based product retail line of baked goods like donuts, pies, pastries, and snack cakes. And according to their website, their top-selling item in the entire Tastykake line of products is the...wait for it...PEANUT BUTTER KANDY KAKES!
And I'm totally not at all surprised by that fun fact!
Is it Peanut Butter Tandy Kakes or Kandy Kakes?
This classic chocolate peanut butter treat goes by a couple of names, actually—Tandy Kakes, Kandy Kakes, and a third one, Tandy Cakes.
I've always known them as Tandy Kakes which was the original name of the product from the store. That name later became Kandy Kakes to avoid confusion with another similar-sounding company.
Then there are others that simply call them Tandy Cakes. People interchange the names a lot, but they're all correct and they all taste equally delicious!
What are Peanut Butter Tandy Kakes?
Peanut butter tandy kakes combine a moist vanilla sponge cake, with a layer of peanut butter, followed by a layer of melted chocolate that is poured evenly over the top.
Just writing that sentence makes me drool. Seriously.
Let's Make Peanut Butter Tandy Kakes!
Whether it's your first time making peanut butter tandy kakes or you simply need a refresher, here's a general guide on how to make them!
- Prep your jelly roll pan. You will need a 15" x 10" x 1" size jelly roll pan and a flour-based baking spray. I highly recommend Baker's Joy. It's just awesome and has never, ever failed me once.
- Make the vanilla sponge cake. You'll need all-purpose flour, baking powder, salt, granulated sugar, vegetable oil, eggs, vanilla extract, and milk for this part. You can use a hand-held mixer, stand mixer, or keep it really simple and just use a large bowl and a whisk. Be careful not to over-mix the cake batter. Bake at 350ºF for 28-30 minutes.
- Add the peanut butter layer. My preference is to use creamy, no-stir peanut butter for this peanut butter tandy kakes recipe. The vanilla sponge cake needs to be almost cooled before you add the peanut butter. If it's just a smidge warm—that's okay.
- Add the melted chocolate layer. You can microwave the semi-sweet chocolate chips and coconut oil together in the microwave, then apply the mixture to the top of the peanut butter immediately. Use an offset spatula for spreading the melted chocolate mixture.
- Let it cool, then cut and enjoy. Refrigerate for 30 minutes to 1 hour before cutting the peanut butter tandy kakes into squares. These are best kept in the refrigerator in an airtight container.

Pam says
I'm going to make this cake as it looks and sounds delicious but was wondering why there is no vanilla in the cake? Does it take away from the peanut and chocolate flavors?
Thank you
Pam
Jennifer says
Thanks Pam, I love to hear that! And thanks for your question too! I've honestly never made it with the vanilla because of having the chocolate and peanut butter layers, but that's just me! I can understand the recipe looking weird without it though, so I did go and add 1 tsp. of it into the recipe!❤️
Jill says
I love making these! They always turn out amazing!! How do you cut them without the chocolate cracking?
Jennifer says
I'm so glad to hear that! I let them sit out at room temperature for about 20-25 minutes before cutting them.
Birdie says
I put the peanut butter on right after the cake comes out if the oven, spreads so much easier..chill it, melt hershey bars and pour on top…easy..and delish.

I agree, Birdie!
Jeannine says
Do you think this would work if I substitute 12 oz of Almond bark in place of chocolate chips?
Jennifer says
I never used it with this recipe, but I don't see why you couldn't try it in place of the chocolate chips!
