Wholesome Ingredients for This Pistachio Oat Squares

Here’s a closer look at the key ingredients that make this recipe so special, along with a few tips and substitutions:

• Pistachios: The star of the recipe, providing protein, healthy fats, and a delightful crunch. Opt for raw, shelled pistachios for the best flavor and nutrition. For a nut-free option, swap pistachios with sunflower seeds.
• Rolled Oats: These provide hearty texture and slow-digesting carbs. Make sure to use certified gluten-free oats if needed. For a lower-carb version, use finely shredded coconut instead of oats.
• Maple Syrup: Adds natural sweetness along with minerals like zinc and manganese. You can substitute it with agave syrup or a sugar-free liquid sweetener for keto adaptations.
• Olive Oil: Enhances moisture and lends a subtle richness with its healthy fat profile. For a more neutral flavor, try avocado oil or melted coconut oil.

How to Make Pistachio Oat Squares

1. Preheat your oven to 350°F and line an 8-inch square pan with parchment paper.
2. In a food processor with the S blade attached, pulse pistachios, oats, and salt until a coarse meal forms—about 30 seconds.
3. With the processor running, drizzle in the maple syrup and olive oil until the mixture forms a crumbly, slightly wet dough.
4. Press the dough evenly into the prepared pan. Sprinkle the surface with coconut flakes and additional chopped pistachios.
5. Bake for 10–12 minutes, until the coconut is golden and the dough is set but still slightly soft. Avoid overbaking!
6. Cool completely in the pan, then use the parchment paper to lift the slab out gently.
7. Cut into squares with a sharp knife and drizzle with extra maple syrup for a touch of sweetness, if desired.
8. Store in an airtight container for up to one week.
