2. Ingredients
These bars use simple pantry ingredients that come together into layers of soft peanut butter filling and glossy chocolate topping. Everything mixes quickly and sets beautifully in the fridge.
Ingredients
- 1 cup melted unsalted butter
- 2 cups graham cracker crumbs (or digestive biscuits, finely crushed)
- 2 cups creamy peanut butter
- 2 cups powdered sugar
- 1 ½ cups chocolate chips (semi-sweet or milk chocolate)
- 2 tablespoons peanut butter (for the chocolate topping)
- A pinch of salt (optional)
Key Ingredients
- Peanut Butter: The star of the recipe. Creamy peanut butter gives a smooth, rich texture that sets nicely once chilled.
- Graham Cracker Crumbs: Add structure and help bind the peanut butter base. Digestive biscuits work equally well.
- Butter: Helps the base firm up and adds richness without baking.
- Powdered Sugar: Sweetens and thickens the peanut butter layer so it becomes sliceable.
- Chocolate Chips: Create a silky chocolate topping that pairs perfectly with peanut butter.
Optional Add-Ons / Variations
- Crunchy Bars: Swap creamy peanut butter with crunchy for added texture.
- Protein Boost: Add ¼ cup vanilla or chocolate protein powder to the base.
- Healthy Twist: Use natural peanut butter and reduce powdered sugar slightly.
- Salted Caramel Drizzle: Add a thin layer of caramel between the peanut butter and chocolate.
- Mix-ins: Mini chocolate chips, chopped nuts, shredded coconut, or pretzel bits.
- Chocolate Peanut Butter Swirl: Swirl extra peanut butter into the chocolate topping before chilling.
3. Step-by-Step Instructions
The workflow is simple: make the peanut butter base, press it into a pan, top with melted chocolate, and let it chill until firm. No baking, no hassle.
Preparation Steps
- Line an 8×8 or 9×9 square baking pan with parchment paper, leaving some overhang for easy lifting.
- Crush graham crackers or digestives into fine crumbs using a rolling pin or food processor.
- Melt the butter and measure out the powdered sugar to ensure smooth mixing.
- Set aside chocolate chips and a small amount of peanut butter for the topping.
Cooking Steps
- In a large mixing bowl, combine melted butter, peanut butter, graham cracker crumbs, and powdered sugar.
- Mix until everything is fully combined and forms a thick, smooth peanut butter dough.
- Transfer the mixture into the lined baking pan and press it down evenly using a spatula or your hands.
- In a microwave or double boiler, melt the chocolate chips with 2 tablespoons of peanut butter.
- Stir until smooth and glossy, then pour the chocolate mixture evenly over the peanut butter base.
- Smooth the top with a spatula to create a clean, even chocolate layer.
- Chill in the refrigerator for at least 2 hours, or until fully set.
- Once firm, lift out using the parchment paper and cut into bars, squares, or rectangles.
Serving Suggestions
- Serve the bars chilled for the best texture.
- Add a sprinkle of flaked sea salt on top for a sweet-salty finish.
- Pair with a glass of milk, iced coffee, or hot chocolate.
- Serve as part of a dessert platter with brownies, cookies, or fruit.
- Wrap individually for lunchboxes or on-the-go snacking.
4. Tips, Substitutions & Notes
These simple tips and substitutions help you tailor the recipe to your taste or dietary needs.
Pro Tips for Better Results
- Use creamy peanut butter for the smoothest texture.
- Press the base firmly so the bars hold together when sliced.
- Add a little extra chocolate if you prefer a thicker top layer.
- Chill longer for perfectly clean slices.
- Warm the knife before slicing for smooth, sharp edges.
Common Mistakes to Avoid
- Using natural peanut butter without adjusting sugar—it may make the base too soft.
- Not pressing the base firmly enough.
- Cutting the bars before they are fully chilled.
- Adding too much butter, which can make the bars greasy.
Ingredient Substitutions
- Butter: Use coconut oil for a dairy-free version.
- Graham Crumbs: Substitute crushed digestive biscuits, Marie biscuits, or oat cookies.
- Chocolate Chips: Use chocolate bars, dark chocolate, or dairy-free chocolate.
- Powdered Sugar: Replace with coconut sugar blended into powder.
Texture, Flavor, or Health Variations
- Extra Creamy: Add an additional ¼ cup peanut butter to the base.
- Dark Chocolate Version: Swap semi-sweet chocolate with 70% dark chocolate.
- Lower Sugar: Reduce powdered sugar by ¼–½ cup.
- High-Protein: Add protein powder and reduce crumbs slightly to compensate.
- Crunchy Texture: Add chopped peanuts or pretzels.
5. Storage & Reheating
No-bake bars store exceptionally well and maintain their structure for days.
Refrigeration
Store bars in an airtight container in the fridge for up to 1 week. Separate layers with parchment if stacking to prevent sticking.
Freezing
These bars freeze beautifully. Place them in a sealed freezer container or zip bag and freeze for up to 2–3 months. Thaw in the fridge before serving.
Reheating
No reheating is needed, but if the chocolate is too firm:
- Let bars sit at room temperature for 5–10 minutes for softer texture.
- Avoid microwaving, as it can melt the chocolate unevenly.
