Boston Cream PIE with a twist
I don’t pretend to be a dessert historian and I have no idea why Boston cream pie is a cake! So I set out to create an actual keto Boston cream PIE inspired dessert that is an actual PIE!
So is this an actual Boston Cream Pie? Nah. But that is the first thing you are going to think about when you take your first bite.
Now, this pie came about pretty quickly actually.
I needed to remake my keto graham cracker pie recipe to retake a few pictures.
So here I sit with a baked pie crust. Now what? Well, perhaps it is time to whip up a new creation. And that is exactly what I did!
Why is Boston Cream Pie called a pie?
Ok, I actually had to look this one up because I had no idea!
Here is a great History of the Boston Cream Pie if you really want to dive into it. But according to the article, Boston Cream Pie IS, in fact, a cake. And it is most likely called a pie because there was a very thin line between cakes and pies long ago!
So, there you have it. It IS a cake. Which is why I set out to make a KETO Boston Cream Pie style dessert that is actually a pie.
I know, I know, I broke all the rules since, well, is it still a Boston Cream Pie? Well, no, but let’s just have a little fun, shall we?
Should Boston Cream Pie be refrigerated?
Most definitely! This low carb Boston Cream Pie should most definitely stay refrigerated AND covered. The chocolate has a tendency to lighten when exposed to too much to air.
How long will the Keto Boston Cream Pie last?
If kept in the fridge, covered, it can last up to 3-4 days. Now, mine generally don’t last nearly that long since they get eaten up immediately! Just make sure to not leave it sitting out as that can cause it to spoil.
Kitchen Essentials
Pie Dish – you will definitely need a PIE dish to make this keto and low carb Boston Cream Pie since, well, it is actually a pie and not a cake! I love using nice pie dishes because it is what I serve it in.
We generally don’t transfer the pie into another dish so bake it in what you will serve it in!
Sauce Pan – you will definitely need an average sized sauce pan in order to cook the cream filling as well as the chocolate topping. You can use the same pan if you wash it between uses!
Flavors
As we’ve talked about, I threw the cake out and decided to use a Keto Graham Cracker Pie Crust. You bet I did!
Why did I choose a Graham Cracker Crust? Well, I know why I chose MY Graham Cracker Crust.
The Boston Cream Pie has 3 delicious and distinct parts. The cake, the cream, and the chocolate.
I have eaten MANY Boston Cream Pies in my past. I’ve even recreated a keto one (the cake version). But I didn’t translate any recipes, I put my own spin on each piece.
Anyone can translate a recipe. I wanted to CREATE one. Ok, so back to the crust.
My Keto Graham Cracker Pie Crust is very popular for good reason. It is incredibly flavorful and is loaded with butter, cinnamon, and toasted almond flour. I thought it would be a GREAT compliment to the cream and chocolate.
As for the cream, I have a signature type cream that I modify for all my various pie needs. It was originally my mom’s recipe that I altered and put my own spin on.
And then the lovely chocolate layer. No cheating here! I mean, it would have been easy to melt some Lily’s chocolate and call it good.
NOPE. We take dark BAKING chocolate, sweeten it and give it some flavor.
Now, when you put this all together, the cream has a delicate, subtle taste that perfectly blends the chocolate with the crust.
It’s perfection really.
