Raise your hand if Reese’s peanut butter cups rank high up there in your favorite candy category (cue me raising both hands and feet ?? ??).  I know there are so many of us that we could easily form a big country.

There’s no denying that these addictive little cups have a cult following, and I’m not ashamed to admit that I’m part of it.  And yet, I haven’t had one (by force, not choice) in so many months that I was starting to get peanut butter cup hallucinations!

Why you ask?

Egypt (where I live and love) hasn’t seen a Reese, among other things, in so long.  You see, the Egyptian pound experienced a staggering devaluation last year, which led to the difficulty of importing products from aboard.  Our government has been trying to limit the import of luxurious or trivial goods, Reese’s included, and support local products instead.

As much as I support the decision, ten months of peanut butter cup withdrawal led to a MEGA peanut butter cup craving, and the craving hit hard!  Spoonfuls of peanut butter studded with chocolate chunks helped, but only to a certain extent.

So what does a Reese-deprived, die-hard lover do when such a craving strikes?  Make an equally MEGA, GIANT peanut butter cup to make up for the lost time!

This oversized peanut butter cup tastes almost identical to Reese’s that you might never buy Reese’s again…not like I have a choice right now but still lol!

It’s incredibly delicious that I could almost swear it rivals the original…but won’t because y’all have your standards.  It’s just that I feel it tastes more like a higher end peanut butter cup, if you will.

It’s also obviously bigger, way way BIGGER…so a “small” slice will give you more than what a package of 2 can.

I also have to love the fact that the ingredients are all easy to find; no supermarket treasure hunting required, and its so easy to make!  You don’t even need to turn on the oven!  And you certainly don’t need to have a shortage of Reese’s to make this.

Just like Reese’s, this knock-off, has that iconic sweet and salty, uniquely textured, creamy filling bursting with peanut butter goodness.

I’ve seen several versions of this creation floating over the internet…but I’m in favor with this one the most, because the texture is just like the real deal.  I found that most recipes, use a filling more akin to a peanut butter frosting; using just butter, peanut butter, and confectioners sugar.  Whereas this one has digestive biscuit (or graham cracker) crumbs in the filling, which adds textural interest and flavor dimension.

As for the chocolate shell, its soft yet sturdy, just the way it should be, so it won’t crack when you slice into it or break a tooth if eaten cold.  The secret is melting the chocolate with a tiny bit of shortening (or oil).  This not only keeps the chocolate nice and sliceable, but it also adds shine, and thins out the chocolate, so it much easier to spread smoothly into the tart pan.

This concoction is so much easier than it looks, so don’t let the fancy fluted tart pan intimidate you!  It practically does the job for you by effortlessly adding in the side ridges and grooves that peanut butter cups are known for.

As you can see below, to get that peanut butter cup-like design, you’ll want to make sure to coat the entire tart pan, including the sides, with the melted chocolate/shortening mixture.  Don’t worry about it being too neat at this point; its the bottom, and will get covered up anyway.  You’ll then chill the pan in the freezer until its set.

Meanwhile, you can make this dead easy filling by pouring a combination of melted butter and peanut butter into a bowl of biscuit/cracker crumbs and powdered sugar.

Stir it up…

Then bring over the chilled tart pan from the freezer…

Spread in the filling…

Then cover with more chocolate.  This time you’ll want to be super neat and work as quick as possible to achieve a smooth finish.

Shake and tap the tart pan over the counter to achieve a nice, smooth finish.

Non-Pro Tip:  If you don’t get it smooth on the first go, you can  totally use a blow dryer to rewarm clumpy areas, and  smooth it out even further.  I totally did that!

Then chill until completely set, inside out.  This should take around 3 hours.

When you unmold the “tart” from the pan, you’ll most likely find some perfect imperfections around the edges.  If they bother you, simply swipe a sharp knife to get rid of anything sticking out.

And that’s pretty much it!

Prep Time 30 minutes
Additional Time 3 hours
Total Time 3 hours 30 minutes


For the Chocolate Shell:

  • 1 cup (180 g) chopped milk chocolate or chocolate chips
  • 1/2 cup (90 g) chopped semisweet chocolate or chocolate chips
  • 1 tablespoon (13 g) vegetable shortening or flavorless oil

For the Peanut Butter Filling:

  • 1 1/4 cup (140g) lightly packed digestive biscuit or graham cracker crumbs (9 biscuits/full sheets)
  • 1 1/4 cup (150g) powdered sugar
  • Tiniest pinch of salt
  • 1/2 cup plus 2 tablespoons (144g) unsalted butter
  • 1 cup plus 1 1/2 tablespoons (269g) creamy peanut butter (not natural-style)


  1. Lightly grease a 9-inch fluted tart pan with a removable bottom, with a thin layer of oil or butter. Top the greased bottom with a circle of parchment paper.
  2. In a medium microwave-safe bowl, microwave the shortening or oil with the chocolate chips in 30 second intervals, stopping and stirring in between until mostly melted. Continue to stir the chocolate mixture, until it has completely melted and very smooth.
  3. Pour a little over half of the melted chocolate amount into the pan. Spread the chocolate all over the bottom, then use a small rubber spatula to bring up the chocolate over the sides. Make sure the entire pan is well coated. Chill in the freezer until set. Meanwhile, prepare the Peanut Butter Filling.
  4. In a large bowl, stir together the biscuit/cracker crumbs, powdered sugar and salt to combine. Set aside.
  5. In another small, microwave-safe bowl or liquid measuring cup, microwave together the butter and peanut butter until the butter has melted; about 1 minute. Stir well to combine. Pour over the dry crumb mixture and stir until well incorporated.
  6. Pour the peanut butter mixture over the chilled chocolate shell and smooth the surface. Shake and tap the tart pan over the counter to smooth out the top even further. Return the pan to the freezer for another 5 minutes to set the surface a little.
  7. Reheat the remaining chocolate mixture until melted once again and is silky smooth. Pour over the peanut butter filling and smooth out with an offset spatula to cover the surface completely. Shake and tap the tart pan over the counter to achieve a smooth finish. If you happen to get a messy area of chocolate that hardened before you got a chance to smooth out, gently heat it with a blow dryer to smooth. Not even kidding lol! It’s how I got mine looking so perfectly smooth 🙂
  8. Refrigerate the tart until completely firm, about 3 hours. Unmold the giant peanut butter cup out of the pan, and peel off the parchment paper from the bottom. Use a sharp knife to smooth out uneven edges.
  9. Cut into slices and serve either chilled, slightly cold or at room temperature. I personally prefer it slightly cold as it somehow tastes less sweet that way and the texture is at its best. The tart will keep well for 5-7 days stored in the refrigerator or frozen for up to 2 months. Thaw frozen slices overnight in the refrigerator.
