Cook Dark Chocolate Pistachio Bars Like This

Step 1: Prepare the Dates
Start by placing the 1 cup of packed pitted dates in your food processor. Blend until they form a sticky paste. If the dates are too dry, you can add a tablespoon of warm water to help them blend smoother.
Step 2: Mix the Base
In a mixing bowl, combine the blended date paste with 1/2 cup of creamy peanut butter, 1/4 cup of pure maple syrup, and 1 teaspoon of vanilla extract. Stir until well combined, creating a sticky mixture.
Step 3: Add the Dry Ingredients
To the wet mixture, add 1 cup of quick 1-minute oats, 1 cup of old-fashioned oats, 1/2 cup of shelled and chopped pistachios, and 1/2 cup of miniature dark chocolate chips. Stir everything together until evenly distributed.
Step 4: Press into the Pan
Line your 9×9-inch baking pan with parchment paper. Transfer the mixture into the pan and press it down firmly and evenly to create a solid base for your bars.
Step 5: Melt the Chocolate
In a double boiler or microwave, melt 1 cup of dark or milk chocolate chips along with 2 teaspoons of coconut oil. Stir until smooth and fully melted.
Step 6: Drizzle the Chocolate
Pour the melted chocolate over the pressed oat mixture in the pan, spreading it evenly with a spatula. You can use a knife or spatula to swirl the chocolate into the oat layer for a beautiful marbled effect.
Step 7: Chill and Set
Place the baking pan in the refrigerator for at least 2 hours to allow the bars to set completely. Once set, remove from the pan by lifting the parchment paper.
Step 8: Cut and Serve
Cut the bars into squares or rectangles, and serve! These Dark Chocolate Pistachio Bars keep well in an airtight container in the fridge for up to a week.
Make It Diet-Friendly

- Nut-Free: Substitute the peanut butter with sunflower seed butter for a nut-free option.
- Vegan: Ensure that the chocolate chips are dairy-free to maintain a vegan recipe.
- Lower Sugar: Reduce the amount of maple syrup to lower the sugar content, or use a sugar alternative.
- Gluten-Free: Use certified gluten-free oats to keep these bars gluten-free.
Little Things that Matter
When making Dark Chocolate Pistachio Bars, the quality of your ingredients can make a significant difference. Opt for fresh, high-quality dates and natural peanut butter without added sugar or oils for the best flavor. Additionally, be mindful of the chocolate you choose; dark chocolate with a high cocoa percentage can add depth to the bars while offering health benefits. Finally, don’t skip out on pressing the mixture firmly into the pan; this helps the bars hold together when you cut them.
Leftovers & Meal Prep
If you find yourself with leftover Dark Chocolate Pistachio Bars, store them in an airtight container in the refrigerator. They should stay fresh for about a week. For meal prep, you can make a double batch and freeze half for later. Just slice the bars and place them in a freezer-safe container, separating layers with parchment paper. Defrost overnight in the fridge before enjoying them again.
Your Top Questions
Can I substitute the dates with another sweetener?
While dates provide a unique texture and natural sweetness, you can substitute them with dried fruit like figs or prunes. However, the flavor and texture may change slightly.
How do I store these bars to keep them fresh?
Store the Dark Chocolate Pistachio Bars in an airtight container in the refrigerator. They will maintain their freshness for up to a week. For longer storage, consider freezing them.
Can I use different nuts instead of pistachios?
Absolutely! You can replace pistachios with any nuts of your choice, such as almonds, walnuts, or cashews. Just make sure to chop them before mixing into the bars.
What’s the best way to melt chocolate without burning it?
Using a double boiler is the best method to gently melt chocolate. If using a microwave, heat in short bursts of 20-30 seconds, stirring in between to prevent burning.
