  • Total Time: 10 Minutes + 2 Hours Chilling
  • Yield: 12 Bars

Ingredients

Scale

Main Ingredients

  • 2 cups (180g) old-fashioned rolled oats
  • 1 cup (250g) creamy peanut butter

Recommended for Best Results

  • 2 tablespoons honey or maple syrup
  • 1 teaspoon vanilla extract
  • ¼ teaspoon fine sea salt

Optional Add-ins

 

  • ¼ cup mini chocolate chips
  • 2 tablespoons chopped roasted peanuts
  • 1 tablespoon chia seeds
  • 1 tablespoon ground flaxseed
  • 2 tablespoons shredded coconut
  • ½ teaspoon ground cinnamon

Instructions

Step 1

Line an 8×8-inch (20×20 cm) baking pan with parchment paper, leaving extra paper hanging over two sides for easy removal.

Step 2

Place the peanut butter in a microwave-safe bowl and warm it for 20–30 seconds until smooth and easy to stir.

Step 3

Add the honey (or maple syrup), vanilla extract, and sea salt. Stir until fully combined.

Step 4

Add the rolled oats gradually, stirring continuously until every oat is evenly coated.

Step 5

Check the consistency.

If the mixture feels crumbly or dry, add 1–2 extra tablespoons of peanut butter until it holds together when squeezed.

Step 6

Transfer the mixture into the prepared pan.

Step 7

Press firmly using the bottom of a measuring cup or silicone spatula for about 2 minutes.

This is the key to bars that don’t crumble.

Step 8

Refrigerate for 1–2 hours until completely firm.

Step 9

Lift the slab from the pan using the parchment paper.

Step 10

Slice into

  • 12 bars
    or
  • 16 snack squares

Serve immediately.

Notes

✔ Use old-fashioned rolled oats, not steel-cut oats.

✔ Natural peanut butter should be stirred well before measuring.

✔ If the mixture seems dry, add more peanut butter.

✔ If the mixture is sticky, mix in a few extra oats.

✔ Chilling is essential before slicing.

✔ Pressing firmly creates compact bars with clean edges.

 

✔ Honey and vanilla are optional but highly recommended for better flavor.
