French Silk Pie Bars

By the way, I hope you all had a great Labor Day weekend. In case you missed my big announcement, be sure to check it out on Instagram.
My little brother came to visit for the weekend. Of course, when I say little, don’t kid yourself. This guy towers over all of us at 6’4″. His favorite dessert is French Silk Pie. We really enjoyed this recipe I made before when he visited us in Boston a few years ago, but this time, I wanted to make something different.
And, let’s be honest, I didn’t want to make a pie. Pies are not my favorite thing to make. I know fall is coming right around the corner, which makes me think of pies, but I’m just not in to them. So bars it was.
As you can see in the pictures, the crust to filling ratio is pretty high on these bars. When I make these again, I’ll reduce the crust recipe to 3/4 of the original. I have reflected the recipe below to reflect that change. The chocolate mousse filling in this recipe is amazing. I’m tempted to just make that part of the recipe again to eat it with a spoon.
Since the crust and filling were both really tall, I didn’t think my pan could handle the whipped cream topping, so I cut the bars and piped it on top. And piping the topping made it look all fancy and fun. I threw the sprinkles on top since I’m lazy and wasn’t in the mood to make chocolate curls… Next time you need a chocolatey travel-friendly dessert to impress your friends, remember these French Silk Bars.

Yield: 16 bars
Ingredients:
For the Crust:
12 Tbsp (1.5 sticks) butter
1 1/2 cups flour
1/3 cup powdered sugar
For the Filling:
8 ounces bittersweet chocolate, finely chopped
1 cup heavy cream
3 eggs
3/4 cup sugar
2 Tbsp water
1 Tbsp vanilla
8 Tbsp (1 stick) unsalted butter, at room temperature, cut into small pieces
For the Topping:
1/2 tsp gelatin
2 Tbsp cold water
1 cup heavy cream
4-5 Tbsp powdered sugar
Directions:
For the Crust:
Preheat oven to 350 degF. Line an 8"x8" pan with parchment paper.
Pulse crust ingredients in food processor 8-10 times until combined. Press crust in to bottom of pan.
Bake for 20-22 minutes or until lightly browned. Set aside to cool.
For the Filling:
Melt chocolate in a double boiler or in the microwave (use 30 second intervals at medium power). Set aside.
Beat the heavy cream to stiff peaks. Place in small bowl and chill in the fridge.
In the bowl of a stand mixer, beat together eggs, sugar, and water until pale yellow and slightly thickened (~6 minutes). Set bowl over saucepan of simmering water and heat mixture to 160 degF, whisking occasionally.
Put bowl on to mixer and beat on medium speed until cooled to room temperature and thickened, about 8 minutes. While beating, add in the chocolate and vanilla. Beat in butter, one piece at a time. Remove bowl from mixer and fold in whipped cream.
Pour mixture over cooled crust and smooth top. Cover and chill for at least 3 hours.
For the Topping:
In a small bowl, sprinkle gelatin over water to soften for 2 minutes. Head 15 seconds in the microwave and whisk to dissolve gelatin. Whip the cream to stiff peaks, adding the gelatin and powdered sugar while whipping.
Spread or pipe on top of bars and chill until set. Decorate with chocolate sprinkles or curls.

loving the baileys idea! mmmmm
I use the same recipe (I think, I’ve had it for years; a standby. I think it was called “Chocolate Fudge Frosting”)
Best thing EVER to do? add a bit of mint extract – it’s very easily my most popular cake filling.. and my favourite icing to eat by the spoonful lol.
I haven’t found the perfect chocolate frosting yet, so I’ll definitely have to try this one!
i definitely, definitely have to try this soon. i can’t get enough of chocolate!
It’s funny about the no milk thing…I was making a new martini recipe that was super strong, so I thought cream would help it become drinkable – but I had no cream, but I did have Vanilla Caramel Coffeemate…it was great!
Ironically, I almost never have milk and always have Bailey’s. Go figure.
Sometimes you really do need a seriously dark chocolatey frosting. This looks absolutely ideal.
you really got into the food styling there — cute pic with the cupcake in the sprinkles.

This sounds nice – I’ll have to try it one day! Jen, have you tried King Arthur Flour’s Supersimple Chocolate Frosting recipe? It is my favourite recipe (so far) for chocolate frosting – I’d definitely recommend it!
(Sheesh! deleted to fix a typo! Wish there was an edit function :))
Pegster – I have not tried the KA recipe. It looks similar to this chocolate frosting recipe which is delicious!
The think I love about this frosting is the stiffness and the fudgeness.
I like this frosting for when I want something quick. Otherwise, I like to use frosting that involves melted, good chocolate for those special occasions. YUM! I would gobble up your cupcakes in a second.
Great call on the Bailey’s – my mom would love that icing. I am going to try this next time I make cupcakes.
I would never think to sub bailey’s for milk. Brilliant. I love my chocolate desserts to be super chocolaty – this looks great!
LOVE the super pink sprinkles too. So pretty 😀
Oh, I forgot to mention that I’m hosting a giveaway. I wonder if it would come handy in this baking project…
These look great!! I love your photos!! I’ve been searching for a good chocolate-y frosting and I think I might try this!!
Would you mind checking out my blog? 😀 http://ajscookingsecrets.blogspot.com/
I could have definitely used this recipe for my sourdough chocolate cake this week
http://gamereviewwiki.com/bikinibirthday/2010/06/21/day-158-binge-weekend/
i just made this frosting today to go inside some cupcakes using your cone method. and i topped with vanilla buttercream, at my hubby’s request.
let me just say this was so delicious i had to take my whitening strips out early so i could lick my fingers, and then the bowl. then my 15 month old attacked me to lick the spatula. we were all sugar high and happy before dinner.
my hubby said “every day i am happier i married you because of things like this”
Thanks for sharing this recipe!!!
Kris – I love hearing comments like that! Thanks for trusting my recipes enough to try on your hubby!
Mmm this looks fantastic, though the ingredients look similar to another delicious recipe I’ve used before that is pretty soft. I’m guessing it’s the butter temperature. Should it be room temperature here? Thanks!
You definitely want your butter at room temperature so it creams nicely.
I have the Bailey’s..lol but I’m out of cocoa powder. Have you ever tried subbing it with melted chocolate? And if so how much do you use?
Best frosting ever. Perfect taste, texture and color. It was divine. I will never use another chocolate frosting recipe ever again. Thank you very, very much! It is truly a gift. 🙂
Jen,
I am a person who has been cooking from the age of 5 ….lol now i have certin likes loves and disliks lol however i found a revepie i wanted to make and it called for a fudge type frosting…. knowing i didnt have one i liked for this so i started looking friday night and didnt come across your recepie until saturday morning so i got out my ingreadience.. but i didnt have Balies or white milk i had some Cream de Mint and Choc. Milk so i straied a tad from ur recepie …. i used 1/2 stick of butter, and to get 1/3 cup of liquid i used aprox 1/4 cup of Cream de Mint and the rest Choc. Milk. Plus the res of ur ingreadience …..omg this is the best dark choc fudge frosting ive ever had!!!! And i used the best dk. Cocoa i know of !!!!!! Thankyou thankyou THANKYOU!!!!!!!!!!!!!
I’m a baker and for the life of me I can’t find a thick chocolate fudge frosting. Is this frosting thick? I don’t want anything too creamy, like ganache when you let it sit. Help please!

This frosting is definitely thick. You can see in the pictures that it held up nicely to piping. It’s not as creamy as a ganache.
Thank you for responding! 🙂 I see that some people use melted chocolate instead of cocoa powder. Doesn’t it really matter?
beantownbaker — February 5th, 2013 @ 10:13 am
For this recipe, I always use cocoa powder.
If I make these the day before do I have to refrigerate them(since the recipe calls for milk)or can I leave them on the counter covered?
beantownbaker — October 30th, 2013 @ 8:21 pm
You can leave them on the counter. The milk in the frosting stabilizes so it won’t go bad. I’d put them in a covered container though.
Hi. Is the butter you use salted or unsalted?
beantownbaker — December 26th, 2013 @ 11:01 am
I always use unsalted butter unless specified as salted butter.
This is absolutely THE BEST chocolate frosting recipe I have EVER tried. I used it to frost some homemade vanilla mint cupcakes and topped them with an Andes mint for my daughters sweet 16 party. I had complete strangers tell me I need to open up a bakery and sell nothing but those cupcakes! Thank you so much for posting this. It is truly amazing.

SO glad you enjoy this recipe! Nothing beats a great chocolate frosting.
I can’t wait to try this! I LOVE the flavor of the hersey’s dark choc frosting recipe but its so thin that i can’t use it for cupcakes, only for a cake. I even tried refrigeration overnight to see if that would thicken it up and it didn’t. so i can not wait try to this one for my cupcakes!
beantownbaker — April 27th, 2014 @ 2:53 pm
I agree. The Hershey’s one is just too thin for cupcakes.
I made a variation on this recipe for my daughter’s birthday cake yesterday and it was fabulous!
I’m still trying to figure out how 6T butter is enough though–I ended up putting in two whole sticks of butter and adding in the milk after the first addition (I added it slowly) of powdered sugar/cocoa combo–it was so thick and dry that my mixer was making new, horrible noises and I was sure it was going to die! LOL
