Save These Peanut Butter Flax Granola Squares are the sort of trusty recipe I rely on for busy mornings or packed lunchboxes. With a blend of creamy peanut butter, hearty oats, and crunchy flaxseed, they hit that sweet spot between wholesome snack and satisfying treat. There is something about the gentle toasty aroma in the kitchen that always reminds me of after-school snacks as a kid except now I get to eat the batter straight from the bowl.
I first made these on a Sunday afternoon for a week of grab-and-go breakfasts. The tray lasted exactly three days no one can resist sneaking a square every time they walk through the kitchen.
Ingredients
- Old-fashioned rolled oats: The hearty foundation of every great granola square They bake up chewy and keep you full
- Ground flaxseed: Adds wonderful nutty flavor plus a boost of fiber and omega-three fatty acids Go for freshly ground if possible
- Chopped roasted peanuts: For crunch and that classic peanut punch Salted or unsalted depends on your taste
- Unsweetened shredded coconut: Optional but brings extra toasted flavor and a subtle chew Look for unsweetened for best results
- Salt: Balances the sweetness and enhances all the nutty flavors Fine sea salt works beautifully
- Creamy peanut butter: This is what binds everything with rich flavor Grab a natural style with just peanuts if you can
- Honey or maple syrup: Offers sweetness and helps everything hold together Honey gives a floral note maple syrup delivers more depth
- Coconut oil or unsalted butter: Helps set the bars and brings extra richness Use refined coconut oil to avoid coconut flavor if desired
- Vanilla extract: Adds warmth and rounds out the flavors Pure vanilla makes all the difference
Instructions
- Prep the Pan:
- Line your eight-by-eight inch baking pan with parchment paper leaving two sides overhanging so you can lift the bars out easily later Trim the paper for a good fit and smooth it into the corners
- Mix the Dry Ingredients:
- Add your oats ground flaxseed chopped peanuts shredded coconut and salt to a large bowl Stir everything together until well combined so you have even flavor in every bite
- Warm the Wet Ingredients:
- In a small saucepan over low heat combine peanut butter honey and coconut oil Stir gently until fully melted and smooth Take the pan off the heat and stir in the vanilla extract This step makes sure all the flavors meld and mixing is easier
- Combine Wet and Dry:
- Pour the melted peanut butter mixture over the oat mixture in your bowl Stir really well to coat every bit of oats and flax This should look glossy and everything should stick together
- Press into the Pan:
- Scrape the mixture into your lined baking pan Use a spatula or your clean hands to press it down very firmly The more you compress the mix the chewier and less crumbly your squares will be
- Bake to Perfection:
- Slide the pan into your preheated three hundred fifty degree oven Bake for eighteen to twenty minutes You want the bars to take on a very light golden color around the edges Watch closely after fifteen minutes because they can brown fast
- Cool Completely:
- Remove the pan and let the bars cool entirely on a wire rack This prevents them from crumbling Give them at least thirty minutes then lift out with the parchment and cut into sixteen even squares For clean edges use a sharp knife and wipe it between cuts
Save My favorite part is the way toasted coconut scents the whole pan I remember my youngest carefully pressing the mixture into the corners with her little hands the first time she helped It has become our Sunday ritual
