Ingredients You’ll Need
Getting the ingredients right is key to nailing this Peanut Butter Shortbread Bars Recipe. Each component is straightforward but plays an essential role—whether it’s giving the base its tender crumb, adding that rich peanut flavor, or ensuring the perfect gooey caramel layer. Here’s a quick guide to what you’ll need:
- 1 ½ cups all-purpose flour (or gluten-free all purpose flour): The foundation for your shortbread crust, providing structure and that classic crumbly texture.
- 1 tablespoon milled flaxseed: Adds a subtle nutty depth and helps bind the crust together naturally.
- 4 tablespoons coconut sugar (or light brown sugar): Offers a gentle sweetness with caramel undertones that perfectly complement the peanut butter.
- ½ teaspoon sea salt: Balances the sweetness and enhances the flavors in the crust.
- ¼ cup smooth peanut butter: Infuses the crust with that unmistakable peanut flavor—go for a quality brand to get the best results.
- ½ cup vegan butter (room temperature): Ensures the crust stays tender and rich without overpowering the peanut notes.
- 2 tablespoons water: Helps bring the dough together just right for pressing into the pan.
- 1 cup smooth peanut butter: The star ingredient for the caramel layer, adding creaminess and depth.
- ¾ cup pure maple syrup: Sweetens and thickens the caramel naturally with a touch of complexity.
- ¼ cup coconut oil (solid): Adds a glossy finish and smooth mouthfeel to the caramel layer.
- 1 teaspoon vanilla extract: Lifts all the flavors and adds a subtle warmth.
- 1 teaspoon sea salt: A pinch in the caramel keeps things perfectly balanced.
- 8.5 oz vegan chocolate: For the luscious chocolate topping that melts in your mouth.
- 3 tablespoons smooth peanut butter: Mixed with chocolate to create an indulgent, creamy topping.
How to Make Peanut Butter Shortbread Bars Recipe
Step 1: Prepare the Crust
Start by preheating your oven to 175°C (350°F) and greasing an 8-inch square pan, then lining it with parchment paper for easy removal later. In a food processor, blend the flour, flaxseed, coconut sugar, sea salt, peanut butter, vegan butter, and water until the mixture clings together into a dough. Press this evenly into your prepared pan and use a fork to gently prick the surface. Baking for around 15 to 18 minutes will give you a golden, fragrant base that’s firm yet tender—the perfect foundation for what’s to come.
Step 2: Make the Peanut Butter Caramel Layer
Next is the luscious peanut butter caramel. Combine peanut butter, maple syrup, coconut oil, vanilla extract, and sea salt in a heatproof bowl. Set this over a double boiler to gently melt and stir everything until smooth and glossy. Pour this thick, dreamy caramel over your cooled shortbread crust. Pop the whole pan into the freezer to set for at least 4 hours. This step is crucial, as it allows the caramel to firm up just enough so it doesn’t mix with the chocolate topping.
Step 3: Create the Chocolate Peanut Butter Topping
The final layer brings all the decadence together. Over a double boiler, melt the vegan chocolate with the peanut butter until wonderfully combined and silky. Pour this rich topping over your set caramel layer, spreading it evenly. Let this chill in the fridge for 15 to 20 minutes until firm. When ready to cut, warm your knife in hot water and dry it—this little trick helps you slice through the bars with clean cuts, keeping each piece perfectly neat and tempting.
How to Serve Peanut Butter Shortbread Bars Recipe
Garnishes
While these bars are stunning all on their own, a sprinkle of toasted chopped peanuts or a light dusting of flaky sea salt adds an extra dimension of texture and flavor. Fresh berries on the side can offer a sharp contrast to the sweet, nutty richness, making each bite even more exciting.
Side Dishes
Serve these bars with a scoop of vanilla or coconut ice cream for a cool counterbalance, or pair them simply with a cup of freshly brewed coffee or tea. Their decadent layers shine brightest when allowed to stand out as the star dessert, so keep accompaniments simple to truly enjoy the magic.
Creative Ways to Present
Presentation is part of the fun! Arrange your Peanut Butter Shortbread Bars Recipe bites on a rustic wooden board alongside small bowls of extra peanut butter and melted chocolate. Or make mini versions in a muffin tin for party-friendly finger foods that everyone will adore. Wrapping individual bars in parchment and tying with twine makes for charming gifts that deliver joy with each bite.
Make Ahead and Storage
Storing Leftovers
These bars love the fridge! Store them in an airtight container to keep the layers fresh and prevent the chocolate from sweating. They should stay deliciously fresh for up to 3 to 5 days, perfect for snacking throughout the week or enjoying a late-night treat.
Freezing
For longer storage, freezing is your friend. Cut the bars into portions and wrap them individually or layer them with parchment paper in a freezer-safe container. They can comfortably freeze for up to 2 months. When you’re ready to eat, thaw in the fridge overnight for the best texture.
Reheating
Because of their layers, reheating should be gentle. Allow bars to come to room temperature or enjoy them slightly chilled. If you want a soft, warm bite, pop them in a low oven for a few minutes, watching closely to avoid melting the chocolate too much.
FAQs
Can I use crunchy peanut butter instead of smooth?
Absolutely! Crunchy peanut butter will add a nice extra texture to your bars, especially in the caramel and topping layers. However, for the smoothest layers, smooth peanut butter is recommended for the caramel and topping to maintain that signature creaminess.
Is this recipe vegan-friendly?
Yes, the Peanut Butter Shortbread Bars Recipe is entirely vegan, using vegan butter and chocolate, making it a perfect plant-based treat without compromising on flavor and texture.
Can I substitute the coconut sugar with regular sugar?
Yes, regular light brown sugar works well as a substitute, giving similar sweetness and a slight molasses flavor that complements the peanut butter beautifully.
How long should I freeze the bars for the caramel to set?
At least 4 hours of freezing is ideal, but overnight works wonderfully too. This ensures the caramel layer is firm enough to hold the chocolate topping without mixing.
What’s the best way to cut the bars without cracking the chocolate layer?
Warm your knife in boiling water, dry it thoroughly, and then cut gently through the bars. The warm blade softens the chocolate just enough for smooth, clean slices every time.

Ingredients
Shortbread Crust
- 1 ½ cups all-purpose flour (or gluten-free all-purpose flour)
- 1 tablespoon milled flaxseed
- 4 tablespoons coconut sugar (or light brown sugar)
- ½ teaspoon sea salt
- ¼ cup smooth peanut butter (e.g., NutShed Original Peanut Butter)
- ½ cup vegan butter (room temperature)
- 2 tablespoons water
Caramel Layer
- 1 cup smooth peanut butter (e.g., NutShed Original Peanut Butter)
- ¾ cup pure maple syrup
- ¼ cup coconut oil (solid)
- 1 teaspoon vanilla extract
- 1 teaspoon sea salt
Topping
- 8.5 oz vegan chocolate
- 3 tablespoons smooth peanut butter (e.g., NutShed Original Peanut Butter)
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 175°C (350°F). Lightly grease the base and sides of an 8-inch square pan with oil or vegan butter and line with parchment paper for easy removal.
- Make Shortbread Dough: In a food processor, combine the flour, milled flaxseed, coconut sugar, sea salt, peanut butter, vegan butter, and water until the mixture forms a sticky dough. Press the dough evenly into the prepared pan and smooth the surface with a spatula or flat-bottom glass. Prick the dough gently several times with a fork to allow for even baking.
- Bake Shortbread: Bake the crust for 15-18 minutes until it turns slightly golden. Remove from the oven and allow it to cool completely to room temperature.
- Prepare Vegan Caramel: In a heat-resistant bowl, combine the peanut butter, maple syrup, solid coconut oil, vanilla extract, and sea salt. Heat this mixture over a double boiler (bain-marie), stirring continuously until it melts into a smooth caramel sauce.
- Assemble Caramel Layer: Pour the warm caramel evenly over the cooled shortbread crust. Place the pan in the freezer and let it set for at least 4 hours or overnight for best results.
- Make Chocolate-Peanut Butter Topping: Melt the vegan chocolate and peanut butter together over a double boiler until smooth and combined. Pour this mixture over the set caramel layer and refrigerate for 15-20 minutes until firm.
- Slice Bars: To cut the bars cleanly, heat a sharp knife by placing it in boiling water, then wipe it dry. Gently slice the bars, letting the warm knife glide through the chocolate and caramel layers.
- Storage: Store the bars in an airtight container in the fridge and consume within 3-5 days. Alternatively, freeze any leftovers and thaw as needed.
Notes
- Use gluten-free flour to keep the bars gluten-free.
- For a nut-free version, substitute peanut butter with sunflower seed butter (adjust caramel layer accordingly).
- Ensure the peanut butter and vegan butter are at room temperature for better mixing.
- Heating the knife before slicing prevents cracking of the chocolate topping.
- Bars can be stored in the freezer for up to 3 months; thaw in the fridge before serving.
