four ramekins filled with keto creme brulee on a beige marble counter

Creme Brulee is, hands down, my favorite dessert of all time. If I go out for dinner and creme brulee is on the menu, I will always get dessert. Creamy vanilla custard topped with a thin layer of caramelized sugar really is the perfect way to end an evening. Like popping bubble wrap, cracking into that layer of burnt sugar with a spoon is just too satisfying to pass up. 

I had no clue how easy this dessert was to make at home. For whatever reason, I thought creme brulee was exclusive to the best chefs. I also thought that in order to make this at home, I would have to buy one of those little kitchen blow torches. Don’t get me wrong, I want a flame thrower, but it seemed like such a silly purchase. Buying a gadget for one purpose is a bit of a waste of kitchen drawer space…and, not to mention, a huge hazard with a 4 year old running around the house. I can envision the mayhem unfurl as I write this post…yikes.

How to make Keto Low Carb Creme Brulee

Sugar-free Creme Brulee Ingredients

  • Unsweetened almond milk
  • Egg yolks
  • Vanilla bean
  • Erythritol
  • Sea salt

Keto Vanilla Custard Dessert Tips & Tricks:

Scrape out the vanilla bean seeds into the milk and toss the entire pod in too. I’ve found the best way to impart the most intense vanilla flavor is to use both the internal vanilla seeds as well as the empty bean itself. Steep it in the milk until it scalds and then remove the bean and discard. You will have vanilla bean flecks in your custard, but in my mind that looks more homemade than just using extract. The flavor is much different too!

How do I remove vanilla bean seeds from the pod? Split the vanilla bean lengthwise by scoring it with a sharp knife. Take the tip of your knife and run it along each of the sides, scraping out the vanilla bean seeds as you go. Be careful not to tear or cut the pod in half, otherwise you’ll be fishing out the tough leathery husk from your milk after it steeps. No one wants to chew on that.

Use a water bath to bake your custards. Place the custard filled ramekins into a 13 x 9 baking dish with high sides. Fill the baking dish with boiling water to the halfway mark of the ramekins. Slowly lower the dish into the oven to bake for 40 to 50 minutes. The custard will be just set with a little wobble, but not set completely. It will continue to firm up as it chills.

No kitchen torch? No problem. Broil it. Sure, this dessert would look beautiful with some custom torching, but if you are like me in trying to keep your superfluous kitchen gadgets at a minimum, you do not own one of these things. After sprinkling your chilled custard with erythritol, you can create the same crunchy caramelized topping in the broiler.

Move a rack to the top so that the custard is as close as it can be to the broiler flames or heating mechanism. You will not need long here! Don’t pop these in and wander off. I will keep the oven open and watch. After the erythritol melts and browns, remove and return to the oven. The custard will get a bit warm again, so if you like this nice and chilled, you’ll want to do this final step about one hour before serving.
