​Sugar Free White Chocolate Fudge Recipe

Simple ingredients. No candy thermometer. No stress. Just creamy homemade fudge for every sweet tooth—without the sugar crash.

If you’ve been around here for a while, you already know two things about me:

1. I’ve got a serious sweet tooth, and
2. I refuse to let that sweet craving derail my low-carb diet, my midlife macros, or my long-term health goals.

And that’s exactly why easy desserts like this Sugar-Free Low-Carb Keto White Chocolate Fudge make me so happy—and why I know you’ll love it too.

It hits that nostalgic “holiday fudge” flavor we all grew up with, but without the added sugar, blood-sugar spikes, or junky ingredients that don’t support our keto diet, ketogenic lifestyle, or weekly midlife macro meal plans.

What I love most?

This keto fudge recipe is truly foolproof. No flour. No baking. No candy thermometer. No stress. Just simple ingredients, a quick melt on the stovetop (or double boiler), and into the fridge it goes.

In about two hours, you’ve got sugar free fudge, velvety smooth, melt-in-your-mouth keto chocolate perfection.

Whether you’re dark chocolate lovers branching into friendlier white chocolate flavors, a long-time fan of my sugar-free chocolate chips recipes, or someone making keto fudge for the first time, this white chocolate version will become a new favorite in your home—and mine.

Even better, it fits beautifully within a low-carb meal plan, keeps your net carbs in check, and still feels like a luxurious treat you’d serve at a holiday party.

Why You’ll Love This Keto White Chocolate Fudge

If you’ve ever tried making fudge the traditional way—lots of sugar, a boiling pot, and a prayer—you know it can be temperamental. But this version? No candy thermometer required. Ever.

Here’s why this recipe is such a win:

It uses nutrient-dense whole foods.

Butter, heavy cream or coconut milk, sugar-free white chocolate, and a touch of vanilla extract. Nothing artificial, nothing complicated.

It satisfies your sweet craving without knocking you off plan.

Even if you’re dealing with hormone shifts, perimenopause, menopause, or blood sugar issues, the good news is this keto white chocolate fudge keeps your carb count and net carbs low.

Just 2 grams net carbs per serving. All nutrition facts are located on the printable recipe card at the bottom of this page.

Room temperature or chilled—always delicious.

This fudge stays creamy even straight from the fridge, thanks to the cocoa butter in the chocolate chips that naturally firms up.

Perfect for holiday gifting or quick treats.

It stores wonderfully, doesn’t melt easily, and feels like a “special occasion” dessert even though it’s incredibly simple.

Ingredient Spotlight

Let’s break down what makes this fudge so creamy, rich, and low carb:

Sugar-Free White Chocolate Chips

Not all white baking chips are created equal. I love Choczero white chocolate chips sweetened with monk fruit and also Lily’s white chocolate sweetened with stevia.

The sugar-free versions melt beautifully, bringing that nostalgic, friendly white chocolate taste without the sugar.

Butter or Coconut Oil

Either option works. Butter gives that creamy, traditional fudge flavor. Coconut oil deepens the richness and keeps it dairy-optional for my friends who follow a dairy-free, coconut-forward, keto lifestyle.

Heavy Cream or Coconut Milk

Both make the fudge silky smooth. Coconut milk also enhances the subtle coconut flavor many of you love.

Allulose

This sweetener creates the best texture—smooth instead of grainy—and keeps the mixture from crystallizing. It also caramelizes slightly, adding depth.

Vanilla Extract + Optional Vanilla Stevia

Adds warmth, dimension, and the classic fudge flavor.

Chopped Pecans (Optional)

A perfect crunch. Or swap with walnuts, almonds, or leave the fudge nut-free for a smooth finish. If you’re a fan of coconut, sprinkle in toasted sugar-free coconut for a macadamia-white-chocolate vibe!

The Story Behind This Recipe

Every year during the holiday season, I get messages from women in my Sugar-Free Mom Tribe Membership asking for low-carb desserts that still feel festive, indulgent, and “worth it.”

So many of you grew up making fudge with your moms, grandmothers, or even your sweet church ladies who always brought the best treats to holiday parties.

But traditionally, fudge is loaded with condensed milk, cups of sugar, and lots of ingredients that don’t work for anyone trying to balance blood sugar, maintain low-carb meals, or pursue long-term health with a sugar-free lifestyle.

That’s why I wanted to create a recipe that:

✔ feels like the best thing on a dessert table

✔ tastes like the fudge you grew up with

✔ and still aligns with a variety of keto, low-carb, high-protein lifestyles

And when I tested this, even my family—who are not sugar-free—said it tasted like “real fudge.” That’s a win in my book!

Holiday flavor ideas

• Cinnamon + pecans
• Crushed sugar-free peppermint
• Vanilla + macadamia nut
• Pumpkin spice
• Salted caramel (use my keto caramel!)

How to Store White Chocolate Fudge

This fudge holds up incredibly well:

• Refrigerator: up to 2 weeks
• Freezer: up to 2 months
• Room temperature: a few hours (great for parties)

It firms up beautifully thanks to the cacao butter in the chocolate and the balanced fat ratio.
