Ingredients You’ll Need
Preparing this Easy Keto Toffee Peanuts Recipe is delightfully simple, requiring only a handful of straightforward ingredients. Each one serves a specific purpose—bringing richness, sweetness, or that comforting spice blend to elevate the humble peanut into a sensational snack.
- 2 cups salted peanuts: Choose high-quality, unsalted or lightly salted peanuts to perfectly balance flavors without overwhelming saltiness.
- 2 tbsp butter, melted: Unsalted butter is best here to maintain control over salt levels while adding rich, creamy texture.
- 1/4 cup erythritol sweetener: This keto-friendly sugar substitute provides the perfect touch of sweetness without any carbs.
- 1 tsp ground cinnamon: Adds a warm, cozy flavor that pairs beautifully with toffee’s buttery notes.
- 1/4 tsp nutmeg: Just a tiny pinch enhances the aromatic spice profile and makes every bite taste extra special.
How to Make Easy Keto Toffee Peanuts Recipe
Step 1: Prepare and Preheat
Start by preheating your oven to 300°F and line a baking sheet with parchment paper. This sets the stage by ensuring your peanuts bake evenly and don’t stick, giving you that perfect crisp finish.
Step 2: Coat the Peanuts
In a large bowl, combine the salted peanuts with the melted butter. Gently toss them until every nut is beautifully coated in buttery richness, which helps the sweet spice blend cling perfectly.
Step 3: Add the Sweet Spice Blend
Sprinkle the erythritol, cinnamon, and nutmeg evenly over the butter-coated peanuts. Toss well again so the spices and sweetener coat each peanut thoroughly—this is where your toffee magic really begins!
Step 4: Bake to Perfection
Spread the coated peanuts out in a single layer on your parchment-lined baking sheet. Bake in the preheated oven for 20 minutes, which lets the flavors meld and the toffee glaze set just right, delivering a crunchy, flavorful bite.
Step 5: Cool and Separate
Once the peanuts come out of the oven, let them cool completely on the pan. Cooling is crucial so they firm up properly; once cool, break apart any clumps gently to reveal your perfect toffee peanuts ready to enjoy.

Make Ahead and Storage
Storing Leftovers
Store any leftover Easy Keto Toffee Peanuts in an airtight container at room temperature. This will keep them fresh and crunchy for up to two weeks, making it easy to enjoy your favorite snack any time you want.
Freezing
If you want to keep your toffee peanuts longer, freezing is an option. Place them in a freezer-safe container or zip-top bag, and they’ll stay fresh for up to 3 months. Just thaw at room temperature before snacking.
Reheating
To refresh their crunch and enhance the buttery aroma, gently reheat your Easy Keto Toffee Peanuts in a preheated oven at 250°F for about 5 minutes. Keep an eye on them to prevent burning, and enjoy them warm!
FAQs
Can I use other nuts instead of peanuts?
Absolutely! Almonds, pecans, or macadamia nuts work wonderfully with this recipe. Just adjust the baking time slightly if nuts are larger or smaller to avoid burning.
Is erythritol the best sweetener to use?
Erythritol works best here because it doesn’t add carbs and caramelizes nicely. However, monk fruit sweetener is a good alternative if you prefer a different keto-friendly option.
Can I make this recipe without butter?
Butter really adds richness and helps the spice blend stick. You could try coconut oil as a substitute, but it will give a different flavor profile.
Will these toffee peanuts be crunchy or chewy?
They come out perfectly crunchy on the outside with a satisfying snap, thanks to the baking process and the toffee glaze setting during cooling.
How long do these keep their freshness?
If stored properly in an airtight container, they maintain great flavor and crunch for up to two weeks at room temperature, making them an excellent make-ahead snack.
