Instructions

  1. Step 1: Preheat oven to 350°F. Spread 1 cup chopped walnuts on a baking sheet and toast for 8-10 minutes until fragrant and lightly browned.

Frequently asked questions

How long does Cambridge-Inspired Maple Walnut Granola Bars take to make?

Total time is about 30 minutes (10 min prep + 20 min cook). Most home cooks find this fits comfortably into a busy morning; prep components the night before to save active time.

How do I store leftover Cambridge-Inspired Maple Walnut Granola Bars?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven; egg- or grain-based items may need a splash of milk or water to refresh texture. Cold-served items (overnight oats, smoothies) keep 2–3 days in the fridge.

Can I substitute ingredients in Cambridge-Inspired Maple Walnut Granola Bars?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Cambridge-Inspired Maple Walnut Granola Bars for a different number of people?

The recipe is written for 12 servings. Multiply each ingredient by (your serving target / 12). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
