Instructions
Preheat convection oven to 300°F (150°C). Line a baking sheet with parchment.
Spread Rice Krispies, oats, and nuts in separate thin layers. Toast for 6–8 minutes, stirring halfway, until lightly golden and fragrant. Watch closely—Rice Krispies brown quickly. Cool completely.
In a medium pot over medium heat, melt the butter. Add thyme sprigs and cook until the butter turns golden brown and smells nutty, 4–6 minutes.
Remove thyme sprigs (a few loose leaves are fine). Stir in a pinch of salt.
Reduce heat to medium-low. Add marshmallows, vanilla, maple syrup, and optional spices. Stir gently until smooth and glossy.
Remove from heat and gently fold in the toasted Rice Krispies, oats, and nuts until evenly coated.
Line a small pan with parchment. Transfer mixture and press lightly with a spatula or buttered hands—do not compact or bars will be dense.
Sprinkle with flaky sea salt, extra candied pecans, and a pinch of thyme leaves. Let cool for 30 minutes, then slice into bars.
