This Millionaire’s Shortbread is the perfect trifecta: Sweet simple, crisp shortbread, rich chewy, homemade caramel, and thick dark chocolate ganache. Sprinkle everything off with a scattering of sea salt and you have a decadently rich treat that lives up to every penny of its lucrative name.
I don’t think (and I’m sure they’ll correct me if I’m wrong) I’ve ever given my siblings anything really bad to eat.
Sometimes they eat my recipe fails, but only the most edible ones (cupcakes that are just slightly too dense, cookies that are a tad too crumbly), and I never did anything as treacherous as trying to pass off bean brownies for regular brownies, which one of my sisters actually did do to me one time (a deception I’ll never forgive).
So it’s slightly insulting to me that, when presented with any dessert that isn’t an obvious cake, cookie, or cupcake, they proceed with severe trepidation. Forks hovering nervously over their plates, eyes narrowed, skeptical, seeming to suggest — It could be an anthrax pie, how can we be sure it’s not? So much for gratitude.
But after explaining for the fourth time to my fourth sibling what Millionaire’s shortbread even is (“It’s like a fancy, homemade, gourmet twix bar”) not a single one seemed the least bit disappointed when they took their first bite.
There’s nothing to be disappointed about when it comes to Millionaire’s shortbread. This is a recipe I’ve been wanting to try my hand at for a while now and after a lot of running around in the kitchen I’m very happy to share it with you.
I don’t think I need to reiterate the fact that it’s a rich dessert — in fact I suggested to my sisters and brother that they cut each giant square into quarters, because while big squares look pretty in these pictures, they’re so rich that it’s a challenge to actually eat a whole one.
The shortbread (a faux shortbread, more on that below) is slightly sweetened but serves as the crispy vehicle to transport chewy caramel and a blanket of chocolate ganache. To make things even more decadent, it’s all topped off with a sprinkle of sea salt. It’s not called Millionaire’s shortbread for nothing!
As attaining millionaire status can change a person, so it has changed our “shortbread” cookie crust here. Surprise, it’s not a “true” shortbread. When I decided to give this classic recipe my own spin, this is one of the first changes I made.
Classic shortbread is made of only three ingredients — butter, flour, and sugar, but this is Millionaire’s shortbread so we’re making sure it lives up to its name.
An egg yolk, some brown sugar, and vanilla extract all make this cookie crust extra flavorful, and slightly softer than standard shortbread as well. Because of the added ingredients, your finished millionaire’s shortbread will cut more easily than standard shortbread (which usually breaks unevenly with jagged edges and scatters crumbs everywhere) but is still crisp and snappy beneath the soft chocolate and chewy caramel.
Andi liked the cookie layer so much she asked me to make her a pan of just that alone, nothing else.
I really wish that I could photograph the processes for these multi-step recipes — a picture of how the crumbled cookie dough should look, the caramel at its peak just before pouring it over the shortbread, the glossy chocolate ganache, etc… but since I only have two days of the week to shoot 3-4 recipes, I usually have to prepare the food Friday night, and there’s no light to take decent pictures then.
To make up for this, I try to include very detailed descriptions in the recipe, and you can always shoot me an e-mail, leave a comment, or drop by my Facebook page if you have any questions.
That being said, I don’t really think you’ll have any problem with this recipe, the trickiest part is the caramel and it doesn’t even require a candy thermometer!
I hope you enjoy this Millionaire’s shortbread as much as my siblings ultimately did!

Recommended Equipment
Instructions
- Preheat oven to 350F (177C) and line a 13x9 baking pan with parchment paper.
- Using an electric mixer, beat butter until well creamed.1 cup (226 g) unsalted butter, softened
- Add sugars and beat until light and fluffy, about 30 seconds.⅓ cup (70 g) sugar, ⅓ cup (70 g) light brown sugar, packed
- Add egg yolk and vanilla extract and stir well, pausing to scrape down the sides and mixing until ingredients are well-combined.1 large egg yolk, ¾ teaspoon vanilla extract
- Add flour, gradually (about ½ cup at a time), pausing to scrape down sides of bowl. Halfway through the addition of the flour, sprinkle in the salt with the beater still running. Don't over-beat the dough, you want it to be slightly crumbly to make it easier to press into the pan.½ teaspoon salt, 2 ¼ cups (260 g) all-purpose flour
- Drop dough over prepared pan and gently, firmly, evenly, press dough into the bottom of the pan. To make it easier, I usually lay a piece of wax paper over the dough and use the palm of my hand to smooth the surface (and then discard wax paper).
- Bake on 350F (177C) for 20-25 minutes -- edges should be lightly golden brown.
- Allow to cool while you prepare your caramel topping.
Caramel
- Combine condensed milk, butter, brown sugar, corn syrup, and salt in a medium-sized saucepan over medium heat.2 14-oz cans (792 g) sweetened condensed milk, 14 Tablespoons (198 g) unsalted butter, 1 cup (200 g) light brown sugar, ⅓ cup (80 ml) light corn syrup, ¾ teaspoon salt
- Stir frequently until butter is melted and ingredients are well-combined. Continue to stir constantly until mixture begins to boil (this could take several minutes, but you don't need to increase the heat).
- Once mixture comes to a boil, reduce heat to a simmer (slowly bubbling), still stirring constantly. Continue to stir 10-15 minutes until mixture turns a rich caramel color and has thickened (should begin pulling away from the sides of the pot as you stir). If using a candy thermometer, the caramel should reach 225F (107C)
- Remove from heat and immediately stir in the vanilla extract.1 teaspoon vanilla extract
- Pour evenly over prepared shortbread, use a knife to spread evenly if needed.
- Allow to cool at room temperature for several hours or in the refrigerator for 1 hour before topping with chocolate.
Chocolate Topping
- Combine chocolate chips and heavy cream in a small saucepan over low heat.½ cup (120 ml) heavy cream, 2 cups (340 g) semisweet chocolate chips
- Stir frequently until chocolate is melted and mixture is smooth.
- Remove from heat and allow chocolate to cool just slightly for about 5 minutes, and then evenly spread over prepared caramel layer. Wait several minutes/until chocolate begins to set and then sprinkle with sea salt.sea salt for sprinkling
- Allow chocolate to harden (I recommend placing in refrigerator for about 30 minutes -- my family prefers these treats refrigerated anyway) before cutting and serving.

I made these exactly as instructed and they are pretty awesome. the shortbread is super yummy and has a perfect crisp! i was worried at first because the dough seemed wetter than i thought it would, but it turned out great. my only complaint is they are verrryyy sweet, which is something i don’t say very often. i almost wonder if you could use half bittersweet or unsweetened & half semi sweet to cut back a smidge. or even maybe cut a 1/4 cup sugar from the filling, but I’m not sure if that would affect the consistency.
Regardless, super awesome recipe and will be making again for a larger crowd! Thank you!
Emily @ Sugar Spun Run
So glad it turned out for you! Yes, this dessert is very rich (hence the name!). You could definitely use a less sweet chocolate next time. Remember to cut it into small portions too 😊
Alice
Hey Sam! This one is such a favourite that i only make it for special occasions. Thank you so much for sharing all your wonderful recipies with us x
Bets
Hi Sam, these are so good!
I would like to know how they should be stored in the fridge – with or without a lid.
I sometimes find that refrigerated goodies “sweat” with a lid on. Also, do you think
that your salted caramel sauce will work for this recipe? Thank so much!
Sam
I would store it with a lid on it. The caramel sauce is too thin to work here, unfortunately. 🙁
Jean M
Is there any way to cut this in half, using an 8×8″ pan? It’s just my hubby and me and I’m afraid if I make the full recipe, I will eat it all!
Emily @ Sugar Spun Run
Hi Jean! That should work. You will need to bake for less time, so just keep an eye on it. 🙂
Nancy
Can you freeze these?
Sam
Hi Nancy! That should work just fine. 🙂

These bars were raved about! I find myself very confident in every new recipe of yours that I try and you DO NOT DISAPPOINT! I made these for friends who are nut lovers and took a chance adding toasted chopped almonds and dried cranberries to the baked shortbread before adding the caramel. I wont say it added anything to these bars (except to please those nut lovers!) Another fantastic and easy-to-follow recipe. Thank you Sam.
Emily @ Sugar Spun Run
Thanks so much for letting us know how it went for you, Maria! Sounds like your guests enjoyed them ❤️
Susana
Thank you so much for such a fabulous, grand dessert! All that I’ve share with can’t say enough good things about it.
Sam
I’m so happy to hear this, Susana! Thank you so much for commenting, I appreciate it!
Linda Wobbe
Wow. Entire family says this is a hit. So easy. All of your enhancements made this sheer perfection. The shortbread is better than traditional. I was worried because ours seemed too much like cookie dough but the texture is perfect, traditionally crumbly when you eat it, but holds together enough to get out of the pan. The carmel is perfect and no thermometer required. We made half the amount of carmel since I only had one can of evaporated milk. I saw some recipes that only use slow cooked condensed milk -traditional dulce de leche. I definitely prefer your richer candy version. We used white chocolate since we aren’t allowed caffeine. I suggest cutting the bars before everything firms up too much. I’m sending a link to this recipe to friends and family. I look forward to trying your other recipes !
Emily @ Sugar Spun Run
We are so happy it was such a hit for you, Linda! Thank you so much for coming back to leave a review–we really appreciate it! ❤️
Abby
Used the caramel portion of your recipe for my bars but added hazelnuts in between the shortbread and caramel layers. I also added some instant coffee powder to the caramel for a little depth and it was amazing! I love your recipe for caramel, its the perfect consistency and sets up so well. Thank you!
Emily @ Sugar Spun Run
Yuuum, that sounds amazing! Thanks for sharing, Abby 😋
Kelly
I don’t know where I went wrong but I can’t get the bars out of pan I only put parchment paper on the bottom the shortbread seems really really crumbly the Carmel is excellent and so is the chocolate. I am leaving in fridge overnight and hope they get firmer I am heartbroken cause my flavors are spot on. I pray 🙏🏼 I can save them 🥲
Sam
I’m so sorry this happened, Kelly! The shortbread may have had a bit too much flour in it if it was too crumbly. Did you press it down into the pan really well when putting it in? I hope you are still able to enjoy it! 🙂
Betta
This is wonderful! The shortbread is just right, not too crumbly and holds up well to the caramel and chocolate. The sea salt adds just a hint of contrast to the sweetness! Very pleased⭐️⭐️⭐️⭐️⭐️
Sam
So happy to hear this, thank you for trying my recipe! 🙂
Shirley Willard
I don’t know where you came from, but suddenly you were in my inbox and I can’t be more pleased. I already had the recipe for the Millionaire Bars, but yours are so much better. Please keep sending recipes.
Cammie Phalan
A real crowd pleaser!

Bridget
Hello! I was hoping to make these ahead of time for holiday gifts. Do you know if I can freeze the entire baked cookie?
Sam
Hi Bridget! Others have frozen the finished product with success. 🙂
Raechel
Do you have a guess as to the volume of caramel? I’ve already made some of my own and looking to use that up. Thanks so much!
Sam
Unfortunately I don’t know the volume. You end up with a layer that’s probably a little more than 1/4 inch thick all the way through if that helps.
Kate
I was really excited about these, but they turned out sickly sweet. After looking through comments, I saw that the butter in the caramel was supposed to be salted. I think this is a super important piece of information that should definitely be included in the main recipe page. In baking, the assumption is that you use unsalted butter. I will probably try them again but tweak the caramel portion a bit.
