Doesn't everyone love peanut butter? Super fudgy, these keto peanut butter fudge bites are great stored in the fridge or freezer. There is no sugar or sweetener added other than the sweet taste from the small dollop of sugar free jam on top of the bite.
I was inspired to make these cute little fudge bites while making my Double Chocolate Fudge Cookies because I enjoyed the little snack with the big flavour, which is very satisfying. It also makes a perfect diabetic friendly snack without spiking my blood sugars just like these Gluten-free Free Collagen Cookies or these Sugar Free Protein Bars.

Ingredients You'll Need for these Sugar Free Peanut Fudge Butter Bites
Only 6 ingredients are needed to make these delicious low carb peanut butter fudge bites.

- Peanut Butter: a smooth all natural creamy peanut butter was used for this recipe to keep carbs low.

Steps by step instructions

How to make Low Carb Peanut Butter Fudge Bites
STEP 1: In a large mixing bowl, combine all the ingredients together with a rubber spatula. Ensure you use softened butter, if cold you can microwave it for about 20 seconds on high to soften it and then add to the natural peanut butter.
STEP 2: Once you get the combined ingredients as smooth as possible, use a small cookie scoop to transfer to a silicone mini muffin pan or mold resting on a baking sheet. Only one scoop per mold. Then place a small dollop of the sugar free strawberry jam on top of each fudge bite.
Freeze for 1 hour, then remove and enjoy.

Recipe tips
This sugar free peanut butter fudge bite recipe is super easy to make, here are a few tips.
Top Tip: using a silicone mold is the easiest way to pop these bites out without struggling. I would not suggest to use a metal muffin pan.
Tip: don't be afraid to use other sugar free jam flavours if you don't have strawberry.
Storage
Set in the fridge: Freeze for at least 1 hour after transferring to the molds.
Serving: enjoy on their own or with your favourite warm beverage.
I prefer to store the bites in the fridge as I like the gooey fudgy texture. However if you prefer a firmer bite, store in the freezer.
Storage: for fudgy bites store in an airtight container in the fridge for up to a week.
If you prefer a firmer fudge bite, store it in an airtight container in the freezer for up to a month. To consume, remove from freezer and let stand at room temperature for a few minutes.
Frequently asked questions
Each fudge bite contains 1g net carb.
One fudge bite contains 1g of sugar and can be safe for diabetics without spiking blood sugars. However, as I always say, different foods affect people differently and you should always check your blood sugars after consuming new foods or recipes.
It's fudgy like fudge but it's fatty and kept cold like fat bites. So I would say it's a hybrid of both.
