My Personal Experience

I’ve always loved fudge, but most versions are packed with sugar, which is a no-go on keto. After experimenting with a few low-carb sweeteners and finding the perfect blend of ingredients, this maple walnut fudge came to life. The best part? It tastes just as good (if not better) than the traditional kind! I make this recipe whenever I’m craving a little indulgence without breaking my carb limit.

Required Equipment

Saucepan

A good-quality saucepan helps melt the butter and sweetener evenly without burning. I prefer one with a thick base to keep the heat stable.

Whisk

Essential for mixing the ingredients smoothly. I always use a sturdy whisk to blend the maple syrup and butter together for a silky texture.

Spatula

A flexible spatula is perfect for folding in the walnuts and spreading the mixture evenly into the pan.

8×8-inch Baking Dish

The right-sized dish ensures the fudge sets to the perfect thickness. I usually line mine with parchment paper for easy removal.

Refrigerator

Chilling is key to getting that perfect firm-but-creamy texture.

Ingredients & Substitutions

• 1/2 cup unsalted butter – Creates the rich, smooth base. You can substitute coconut oil for a dairy-free version.
• 1/2 cup sugar-free maple syrup – Gives that perfect maple sweetness. Monk fruit syrup or a mix of erythritol and vanilla extract works as an alternative.
• 1/2 cup heavy cream – Adds creaminess. You can swap with coconut cream for a dairy-free version.
• 1 tsp vanilla extract – Enhances the overall flavor.
• 1/4 tsp maple extract – Boosts the maple taste. If you don’t have it, add a little extra vanilla.
• 1/2 cup chopped walnuts – Brings crunch and nuttiness. Pecans can be a great alternative.
• Pinch of salt – Balances the sweetness and enhances flavors.

How to Make Keto Maple Walnut Fudge

1. Melt the butter – In a saucepan over medium heat, melt the butter and stir in the sugar-free maple syrup.
2. Simmer the mixture – Add the heavy cream and bring it to a light simmer, stirring frequently. Let it cook for 3-5 minutes until slightly thickened.
3. Remove from heat – Stir in the vanilla extract, maple extract, and a pinch of salt. Mix well.
4. Add the walnuts – Fold in the chopped walnuts to distribute them evenly throughout the mixture.
5. Pour into the dish – Line an 8×8-inch dish with parchment paper and pour the fudge mixture in, smoothing it out with a spatula.
6. Chill until firm – Refrigerate for at least 2 hours or until set.
7. Cut and serve – Once firm, cut into squares and enjoy!

Tips for This Recipe

• Use high-quality butter – This affects the richness of the fudge.
• Chill completely – If the fudge isn’t fully set, it won’t hold its shape when cut.
• Adjust the sweetness – Taste the mixture before chilling and adjust the sweetener if needed.

Optional Additions

• Cinnamon – Adds warmth and depth to the flavor.
• Dark chocolate drizzle – If you love a chocolate-maple combo, drizzle some melted keto-friendly chocolate on top.
• Sea salt flakes – A sprinkle on top enhances the flavor contrast beautifully.

Serving Ideas

• Enjoy with a hot cup of keto coffee or tea.
• Serve as a dessert after a low-carb meal.
• Cut into small bite-sized pieces for a party platter.

Storage Recommendations

• Refrigerator – Store in an airtight container for up to a week.
• Freezer – Freeze in an airtight container for up to a month. Thaw in the fridge before eating.
