About This Recipe

This Keto Spiced Maple Walnut Fudge (Sugar-Free) delivers everything you want from a classic holiday fudge—creamy texture, warm spices, sweet maple flavor, and crunchy walnuts—without any sugar. Traditional maple fudge is loaded with syrup and high-carb ingredients, but this keto-friendly version recreates the same nostalgic flavor with clean, low-carb substitutions that keep the macros perfect for a holiday treat.

The base is made by melting butter, heavy cream, and sugar-free maple syrup together until smooth and slightly thickened. Powdered sweetener enhances the sweetness while staying silky and smooth, avoiding the gritty texture that can sometimes come from keto sweeteners. Cinnamon and nutmeg add cozy winter spice, giving the fudge a warm, festive flavor profile that pairs perfectly with the maple notes. The chopped walnuts fold into the mixture at the end, adding texture and a satisfying crunch.

Once poured into a parchment-lined dish and chilled, the fudge sets into a soft, creamy block that slices cleanly into bite-sized squares. It’s rich without being heavy, sweet without spiking blood sugar, and perfectly balanced by the nutty flavor of the walnuts. The recipe is simple, quick, and ideal for December dessert platters, gifting in festive tins, or storing in the fridge for a daily holiday treat.

This fudge also holds up well in the freezer, making it perfect for prepping ahead of gatherings or saving for later. The flavor deepens over time, becoming even more delicious after sitting for a day. If you’re looking for a holiday dessert that brings classic comfort with keto-friendly ingredients, this spiced maple walnut fudge is a must-have for your winter recipe lineup.
