Ingredients

For the Butterfinger Center:

  • 1/2 cup pork rinds, finely crushed (or substitute with 1 cup of keto-friendly puffs, crushed)

  • 1/2 cup sugar-free peanut butter (creamy, made with no sugar added)

  • 1/2 cup powdered erythritol/monk fruit sweetener (like Swerve Confectioners)

  • 1/2 cup allulose syrup (this is key for a hard, non-grainy texture; do not substitute with other liquid sweeteners)

  • 2 tablespoons water

  • 1 teaspoon vanilla extract

  • Pinch of sea salt

For the Chocolate Coating:

  • 1 cup sugar-free chocolate chips (I recommend a brand like Lily’s or ChocZero)

  • 1 tablespoon coconut oil (or refined coconut oil for no coconut taste)

Instructions

Step 1: Prepare the “Crispies”

In a medium mixing bowl, combine the finely crushed pork rinds (or keto puffs) with the sugar-free peanut butter. Use a fork or your hands to work them together until the mixture resembles a wet, clumpy sand. Set aside.

Step 2: Create the Candy Syrup

Line a small 8×4 inch loaf pan or a similar small dish with parchment paper, leaving some overhang on the sides. This will make it easy to lift the candy out later.

In a small, heavy-bottomed saucepan, combine the allulose syrup, water, and a pinch of sea salt. Place over medium heat. Stir constantly until the mixture comes to a gentle boil. Once boiling, stop stirring and let it cook for 3-5 minutes. Keep a close eye on it. You’re looking for it to thicken slightly and darken just a shade. If you have a candy thermometer, you want it to reach about 240-245°F (soft-ball stage) . The mixture should be bubbly and look like a thick syrup.

Step 3: Combine and Form the Center

Remove the pan from the heat. Immediately pour the hot syrup over the peanut butter and “crispie” mixture. Add the vanilla extract. Work quickly! Stir vigorously with a strong spatula until everything is completely combined and the mixture forms a cohesive, sticky dough.

Press the mixture firmly and evenly into your prepared loaf pan. Use the back of a spatula or a piece of parchment paper to really compact it down. The firmer you press, the better your bars will hold together. Place the pan in the refrigerator to chill for at least 20 minutes, or until it is completely firm to the touch.

Step 4: Slice the Bars

Once firm, use the parchment paper overhang to lift the entire block of candy out of the pan. Place it on a cutting board. Using a large, sharp knife, cut the block into 8 even bars. You can cut them smaller for bite-sized pieces if you prefer.

Step 5: The Chocolate Coating

Place the sugar-free chocolate chips and coconut oil in a small, microwave-safe bowl. Microwave in 30-second intervals, stirring thoroughly after each, until the chocolate is completely smooth and melted. Be careful not to overheat it.

Using two forks or a dipping tool, dip each bar into the melted chocolate, turning to coat it completely. Let any excess chocolate drip off back into the bowl. Place the coated bars on a piece of parchment paper or a wire rack set over a baking sheet.

Step 6: Set and Serve

Once all bars are coated, return them to the refrigerator for another 10-15 minutes to allow the chocolate shell to harden completely.

Once set, your Keto Butterfinger Candy Bars are ready to enjoy! For the best texture, store them in the refrigerator.

Chef’s Tips

  • The Allulose is Crucial: Allulose syrup is the magic ingredient here. Unlike other sweeteners, it doesn’t recrystallize when it cools, giving the center that authentic, hard-but-crunchy Butterfinger snap. Do not substitute with honey, maple syrup, or other keto syrups, as they will result in a sticky, chewy center.

  • Crush Finely: For the best texture that mimics the original, you want your pork rinds or keto puffs crushed into very fine crumbs. You can put them in a zip-top bag and crush them with a rolling pin, or pulse them a few times in a food processor.

  • Work Fast: The sugar syrup will begin to set as soon as it hits the cooler peanut butter mixture. Be prepared to stir and press it into the pan immediately.

Storage Instructions

  • Refrigerator: Store the finished bars in an airtight container in the refrigerator for up to 2 weeks. They are best enjoyed cold, straight from the fridge.

  • Freezer: These bars freeze beautifully! Place them in a single layer in a freezer-safe container or bag, separated by parchment paper. Freeze for up to 3 months. Enjoy straight from the freezer for an extra-cold, crunchy treat.
