In a large mixing bowl, add 2 cups of rolled oats, 1 cup of nut butter, 1/2 cup of honey or maple syrup, 1 teaspoon of vanilla extract, and a pinch of salt. Mix until combined.

Once the base is prepared, fold in 1/2 cup of mini chocolate chips and any optional chopped nuts or seeds you'd like to include. Stir gently until evenly distributed.

Line an 8x8 inch baking dish with parchment paper. This helps prevent sticking and allows for easy removal.

Transfer the oat granola mixture into the lined baking dish and pack it down firmly using a spatula to ensure it’s compacted.

Place the baking dish in the refrigerator for at least 1 hour to let the mixture firm up.

After an hour, carefully lift the mixture out using the parchment paper. Transfer it to a cutting board and slice into bars.
