Lightly toast rolled oats in a dry skillet for 2-3 minutes before combining with wet ingredients to deepen their nutty flavor and improve crunchiness in the final cups.

Warm maple syrup and olive oil together before mixing to create a cohesive emulsion that coats oats evenly, preventing dry patches and ensuring consistent sweetness throughout.

Use light, neutral olive oil or refined coconut oil instead of heavy-flavored varieties to let the maple and vanilla shine without competing flavor profiles.

Toast larger nuts separately and add them in two stages—half mixed into the granola base and half pressed firmly on top before baking—for better texture contrast and visual appeal.

Press the warm granola mixture into muffin cups immediately after removing from the oven while still pliable, then let cool completely before unmolding for clean, sturdy cups that hold their shape.
