Types Of Keto Butter Tarts

Hours after I landed in Canada from the UK, my wife had me try old-fashioned Canadian butter Tarts.

She insisted I try one or two if my sweet tooth needed a boost to stay awake after the fight.

They are delicious and remind me of eating sweet, flaky pastry pies but single portion sizes.

I’ve tried many butter tarts in my years living in Canada and decided to create a keto recipe.

With my mother-in-law diabetic and both of us following a keto lifestyle, making these before Canada Day was natural. 

The trick is to make them last longer than a few days, as they are SO tempting even when frozen.

What is a Butter Tart?

Canadian Butter Tarts symbolize excellent cuisine in our country. They start with a flaky, buttery pastry and end with a deliciously sweet centre.

Traditional Canadian Butter Tarts are super sweet, and when you bite into them, you’ll find the centre is a thick dark syrup consistency. 

A butter tart is a small pastry tart, which generally consists of butter, sugar, syrup, and egg, filled into a flaky pastry and baked until the filling is semi-solid with a crunchy top.

Filling Changes Using Different Ingredients

Depending on the pie crust recipe, you will find tarts with a thicker centre and a deep-colored pastry. 

If you add more butter, your crust will be golden brown and flakier, which tastes great.

You will see the difference in the photos below as I show variations of my butter Tarts. 

An original recipe for butter tarts follows sugar pie beginnings without nuts or dried fruit variations like you can get today.

The butter tart filling recipe I chose went through many tests in our house as we tried to get that sweet, liquid texture. 

First off, you will see photos of two different filling styles where one uses Sukrin Gold brown sugar and the other Swerve confectioners sugar.

They are both delicious, but I prefer the Sukrin gold to get the classic butter tart golden filling colour.

That’s never a problem for Sweet and Keto, but finding the old-fashioned butter tart consistency was challenging.

Essentials For A Gooey Centre

Each time I tried making the recipe, the filling always baked gooey but ended firm after it cooled.

I still think adding vegetable glycerin is essential (optional) to help keep somewhat of a gooey texture along with the xanthan gum.

As you will see, the filling looks like creamy caramel, but after baking, it will thicken as it doesn’t have corn syrup.

Tips For Keto Pastry Making

I’ve learned three things when making any keto recipe with a gluten-free pastry.

  1. They are better two days later and frozen or chilled first.
  2. Keto Butter Tarts may not look identical to old-fashioned butter tarts, but they taste similar.
  3. After you microwave it or add heat, you’ll only accomplish a traditional runny butter tart filling texture.

Easy Keto Baking

I consider it easy to make these butter tarts as I’ve tried not to complicate the recipe with unnecessary steps or ingredients.

The idea is to keep it close to Canadian tradition for those following the Keto diet.

However, if you want to add chopped walnuts or pecans, we tried both; they taste amazing.

Always Get Second Opinions

A friend who taste-tested our tarts messaged us that they were the best butter tarts she’d ever tried.

She typically buys them at a local Keto bakery, says ours has beaten them hands-down, and now wants to place orders with us.

Ha! I couldn’t imagine mass-producing these in our kitchen for sale, but many people sell Keto baked goods from their homes.

It was nice to get that compliment from someone who follows Keto.

Gluten-Free Butter Tart Shells

I tried variations of butter tart shells and returned to the same recipe for my Keto Cheesecake.

This butter tart pastry has no cream cheese, as in many other keto pastries.

I was not too fond of the tangy flavour or hints of cream cheese, so I left it out.

It’s not bad, but it didn’t fit the traditional part of the Canadian butter tart.

Simple Keto Butter Tart Pastry

To keep the keto tart shells simple, you will need almond flour, cold butter, salt, sweetener, and Vanilla.

I want to point out that this recipe has no rolling of pastry.

Just press a scoop into the muffin tin; it’s that easy.

I tried to roll it out, but it got too complicated and time-consuming, and this press-it-in method works.

Also, ensure you spray your muffin tins with cooking spray.

They won’t come out easy, even with butter in the pastry, but I have a hack.

How To Get The Best Results

I have a little trick to get butter tarts out quickly. I freeze them first.

Once the butter tarts are cold, I stick a knife in the corner, and they pop out.

Over the past six months, I’ve made many variations of these butter tarts.

Some of my recipes were great; others were not complete flops but needed tweaking.

I did not freeze them the other three times.

First, I went with the cooldown method and then removed them.

They don’t fall out if you turn the pan over, either.

The sugary butter tart filling tends to bubble up and over, causing the butter tart to stick.

I tried the butter tarts in a large muffin tin and jumbo muffin tins and found the jumbo muffin tins to be the best.

The giant muffin tins allow for a thicker crust and more room for the filling to bubble up and be far easier to remove.

That’s just my choice, but you can use any size muffin tin you like.

My recipe makes six giant butter tarts.

  1. Hi Mr.CBB,
    OMG, I made a test batch of the Keto Butter Tarts last night and had one this morning.
    All I’m going to say is how am I going to control myself around them. They are AMAZING and taste like butter tarts.
    Thanks for this recipe. I’ll be making a few batches for Christmas.

  2. They absolutely look delicious! Excited to try the recipe. In the recipe under Buttertart ingredients you state 1/4 butter, I trust you meant 1/4 cup butter?If Sukrin golden sugar is not available in my area, would I just substitute a sugar free brown sugar? How many carb or net carbs are in these buttertarts?

  3. Have you done an article summarizing your keto journey? I recall reading Mrs. CBB was following keto but I see above you are now following as well. I would be interested in knowing more about that part of your life.
