- 1 cup creamy peanut butter
- ½ cup coconut flour

How to Make These Amazing Bars
Four ingredients. No oven. So easy! Follow these simple steps for perfect No-Bake Chocolate Peanut Butter Bars every time.
- Prepare your pan: Line a 5×9 loaf pan (or an 8-inch square pan) with parchment paper, leaving enough overhang on the sides to use as handles (this creates a “sling” for easy removal). Set aside.
- Make the peanut butter layer: In a mixing bowl, stir together the peanut butter and coconut flour until well combined. The mixture should be thick and dough-like. Transfer to the prepared baking pan and smooth it out evenly using an offset spatula or the back of a spoon. Place the pan in the freezer while you make the chocolate layer.
- Melt the chocolate: In a glass bowl set over a double boiler (a pot of simmering water), heat the chocolate chips and coconut oil until melted. Stir occasionally to combine gently. A double boiler gives you more control than a microwave and prevents the chocolate from burning. Once melted, allow the chocolate to cool for about 5 minutes.
- Assemble and freeze: Pour the melted chocolate over the frozen peanut butter layer, spreading it evenly with a spatula. Return the pan to the freezer for at least 1 hour, or until the chocolate is completely set.
- Slice and serve: Remove the bars from the pan using the parchment paper sling. Transfer to a cutting board and slice into 8 bars (or more if you prefer smaller portions). Store in an airtight container in the refrigerator.

Substitutions & Variations
These No-Bake Chocolate Peanut Butter Bars are incredibly flexible. Here are some easy swaps to make them work for your dietary needs or taste preferences:
- Vegan: Use vegan semi-sweet chocolate chips (most dark chocolate is naturally vegan).
- Different chocolate: Try dark chocolate for a richer, slightly bitter flavor, or milk chocolate chips for a classic peanut butter cup taste.
- Crunchy peanut butter: Swap creamy peanut butter for crunchy peanut butter for added texture and a completely different experience.
- White chocolate: White chocolate would also work beautifully—try white chocolate chips with a drizzle of dark chocolate on top.
- Nut-free: Use sunflower seed butter (sunbutter) instead of peanut butter to make these allergen-friendly. Note that the color may turn slightly greenish (this is a natural reaction and safe to eat).
- Different nut butters: Swap the peanut butter for almond butter, cashew butter, or even tahini for a unique twist.
- Coconut flour substitute: If you don’t have coconut flour, you can use almond flour or oat flour, but you may need to adjust the quantity (start with ¼ cup and add more as needed).

Add-Ins & Toppings
While the simplicity of these No-Bake Chocolate Peanut Butter Bars is what makes them so appealing, you can definitely make them your own with these delicious add-ins:
- Sprinkle on top: Pumpkin seeds, sunflower seeds, chopped walnuts, or almonds add wonderful crunch.
- Unsweetened coconut: Toasted or untoasted shredded coconut on top of the chocolate layer is amazing.
- Flaky sea salt: A sprinkle of Maldon sea salt on top of the wet chocolate takes these bars to the next level.
- Crushed peanuts: For extra peanut flavor and texture, press crushed peanuts into the top before the chocolate sets.
- Drizzle: Once the chocolate is set, drizzle with white chocolate or additional peanut butter for a decorative finish.

How to Store Chocolate Peanut Butter Bars
These No-Bake Chocolate Peanut Butter Bars need to be kept cold, as the coconut oil and chocolate will soften at room temperature.
Refrigerator: Store covered in an airtight container in the refrigerator for up to 1 week. They’re delicious cold—the chocolate stays snappy and the peanut butter layer stays firm but creamy.
Freezer: These bars freeze beautifully! Wrap each bar individually in plastic wrap or parchment paper, then place in a freezer-safe bag or container. They will keep for 3 to 6 months. Eat them straight from the freezer for a firm, candy-bar-like texture, or let them thaw for 5-10 minutes at room temperature for a softer bite.
Meal prep tip: Make a double batch and keep half in the fridge for immediate snacking and half in the freezer for later. These bars are perfect for lunchboxes, after-school snacks, or unexpected guests.

Frequently Asked Questions
Yes! Almond flour or oat flour can work as substitutes. Start with ¼ cup and add more as needed until the mixture holds together when pressed. You can also use ½ cup of powdered sugar or graham cracker crumbs, but note that this will change the flavor and sweetness level.
A double boiler provides gentle, indirect heat that melts chocolate slowly and evenly without burning. While you can use a microwave (in 15-second bursts, stirring between each), the double boiler method gives you more control and results in a shinier, smoother chocolate layer.
Natural peanut butter (the kind with oil separation) will work, but the texture may be slightly softer and oilier. Stir it very well before using. For best results, use a standard creamy peanut butter like Skippy or Jif, which contains stabilizers that help the bars hold their shape.
At least 1 hour is recommended for the chocolate to fully set. For best results, freeze for 2 hours. If you’re in a hurry, you can refrigerate for 3-4 hours instead, but the freezer gives you a cleaner slice and snappier chocolate.
Yes! Coconut flour is naturally gluten-free. Just make sure your chocolate chips are certified gluten-free if you have celiac disease or severe sensitivity (most semi-sweet chocolate chips are gluten-free, but always check the label).
Absolutely! Add 1-2 scoops of vanilla or chocolate protein powder to the peanut butter layer. You may need to add an extra tablespoon of coconut flour or a splash of milk to achieve the right consistency.
