Line an 8×8-inch baking pan with parchment, leaving overhang for easy lifting. Lightly mist or rub with oil.

In a dry skillet over medium heat, toast oats and nuts for 3–4 minutes until fragrant. Cool slightly. This adds depth and helps the bars hold together.

In a small saucepan, combine peanut butter, honey, and coconut oil. Heat on low, stirring until smooth and glossy. Remove from heat; stir in vanilla and salt.

In a large bowl, mix oats, crisped rice, nuts, seeds, and dried fruit. If using protein powder or spices, whisk them in now.

Pour the warm mixture over the dry ingredients. Stir until every oat is coated and the mix looks sticky, not dusty.

Let the mixture cool 2–3 minutes, then fold in chocolate chips so they don't fully melt (unless you want chocolate swirls, which is also elite).

Transfer to the pan. Press firmly with a spatula or the bottom of a measuring cup. The firmer you press, the better the bars hold.

Refrigerate for 60–90 minutes, or freeze for 25–30. Lift out and slice into 10–12 bars with a sharp knife.

For thick, bakery-style bars, use a loaf pan. For more snack-sized bites, cut into 16 squares.
