Is Peanut Butter Keto?
Yes! Peanut butter is keto-friendly when consumed in moderation. Always choose a no-sugar-added peanut butter with only two ingredients: peanuts and salt.
According to the USDA, 2 tablespoons of peanut butter contain 4g net carbs and 190 calories, making it a great addition to a low-carb diet.
Possible Benefits Of Peanut Butter
- Supports Heart Health: Regular consumption of peanuts and peanut butter has been associated with reduced cardiovascular disease risk and improved lipid profiles, including lowering LDL cholesterol.
- Rich in Nutrients: Peanut butter is a good source of essential vitamins and minerals, such as vitamin E, magnesium, and potassium, which are vital for overall health.
- Antioxidant Properties: The antioxidants in peanuts, including vitamin E and resveratrol, help protect the body from oxidative stress caused by free radicals.
- May Aid in Weight Management: Despite its calorie density, peanut butter’s combination of protein, healthy fats, and fiber can promote satiety, potentially aiding in weight management.
Ingredients for Keto Peanut Butter Bars
Only six simple ingredients are needed to make these delicious keto peanut butter chocolate bars! That’s right—just six pantry staples, and you’re on your way to a rich, creamy, and chocolatey treat.
- Peanut Butter – The star of the recipe! Choose a no-sugar-added peanut butter for a truly keto-friendly treat. Smooth peanut butter works best for a creamy texture.
- Almond Flour – This grain-free flour provides structure and replaces the classic graham cracker crumbs traditionally used in peanut butter bars.
- Butter – Both salted or unsalted butter work well in this recipe. If you prefer, coconut oil can be used instead—opt for refined coconut oil to avoid a coconut flavor.
- Sweetener – Use a powdered keto sweetener for easy mixing and a smooth texture.
- Vanilla Extract – Go for the best quality vanilla extract you can find—it makes a difference!
- Chocolate – The finishing touch! Use chopped dark chocolate or sugar-free semi-sweet chocolate chips to create the rich chocolate layer on top.
How To Make No-Bake Keto Peanut Butter Bars
You will be surprised at how easy it is to prepare this dessert. Here is everything you have to do:
Mix the Peanut Butter Dough
In a large bowl, combine peanut butter, almond flour, melted butter, powdered sweetener, and vanilla extract. Mix until a thick, cookie dough-like mixture forms. It should be soft but hold its shape when pressed—if it’s too dry, add a teaspoon of melted butter or peanut butter; if too wet, a bit more almond flour.
Press Into a Pan
Line a 8×8-inch (or similar-sized) square pan with parchment paper, leaving an overhang for easy removal. Transfer the peanut butter mixture into the pan and press it down firmly into an even layer using the back of a spoon or a spatula. For extra smooth bars, you can lightly grease your hands and press it down evenly.
Melt the Chocolate
In a microwave-safe bowl or using a double boiler, melt the chocolate chips until smooth. For a silkier, softer chocolate layer, stir in 2 tablespoons of peanut butter while melting. This prevents the chocolate from cracking when you slice the bars and gives it a creamier texture.
Spread & Chill
Pour the melted chocolate over the peanut butter layer and spread evenly with a spatula. Give the pan a gentle shake or tap on the counter to smooth it out. Refrigerate for at least 2 hours, or until the bars are completely firm.
Slice & Serve
Before cutting, let the bars sit at room temperature for about 10 minutes—this helps prevent the chocolate from cracking. Use a sharp knife, preferably warmed slightly (just run it under hot water and dry), to slice clean, even bars.
Tips For Making The Best Keto Peanut Butter Bars
- Line your pan properly – Use parchment paper or foil with an overhang to make lifting the bars out of the pan super easy. This prevents sticking and makes slicing a breeze.
- Use high-quality, smooth peanut butter – Since peanut butter is the star of this recipe, choose one with a rich, natural peanut flavor and no added sugar or oils. Smooth peanut butter creates the creamiest texture.
- Customize with different nut butters – Not a peanut butter fan? Swap it out for almond butter, cashew butter, or even sunflower seed butter for a different but equally delicious flavor.
- Make slicing easier – Let the bars sit at room temperature for 10 minutes before cutting to prevent the chocolate from cracking. Using a sharp knife warmed under hot water (then dried) helps make clean, even slices.
- Want a little crunch? – Stir in chopped nuts, crushed keto-friendly cookies, or sugar-free chocolate chips to add texture to the peanut butter layer.
- For an extra indulgent touch – Sprinkle flaky sea salt on top of the chocolate before chilling. The sweet-salty combo is next level!
Recipe Variations and Tips
- Add Some Crunch – Sprinkle chopped peanuts, hazelnuts, or even almonds on top before the chocolate sets for a delicious crunchy texture.
- Sweet & Salty Perfection – Before the chocolate hardens, sprinkle flaky sea salt on top. This enhances the peanut butter flavor and balances the sweetness beautifully.
- Extra Chocolatey? Yes, Please! – Stir a handful of sugar-free chocolate chips into the peanut butter mixture for extra chocolate in every bite.
- Softer Bars? No Problem! – Mix in a small amount of coconut oil with the peanut butter mixture to make the bars creamier and softer straight from the fridge.
- Turn Them Into Keto Peanut Butter Balls! – Instead of pressing the peanut butter mixture into a pan, roll it into small balls, then dip or drizzle with melted chocolate. They taste like keto-friendly Reese’s truffles!
How To Store No-Bake Keto Peanut Butter Chocolate Bars
- Fridge: Store these peanut butter chocolate bars in an airtight container in the refrigerator for up to two weeks. This keeps them firm and fresh while maintaining the perfect texture.
- Freezer: Want to keep them longer? These bars freeze beautifully! Slice them into portions and place them in a single layer in an airtight container (or separate layers with parchment paper). Freeze for up to three months.
- To Serve from the Freezer: Let the bars sit at room temperature for 5-10 minutes before eating, or enjoy them straight from the freezer for an extra-firm, fudge-like texture!
