I often make this granola recipe from one of my favorite baking books,
Baked: New Frontiers in Baking. While I wouldn't exactly call it healthy, I would definitely call it delicious (unlike much of that bird-seed-type granola you see out there). It is great by itself, with milk, or with yogurt, and the recipe can be easily altered depending on the kinds of nuts and fruits you like.
Easy Homemade Granola
adapted from Baked recipe
Ingredients:
2 cups rolled oats
1 teaspoon cinnamon
1 teaspoon salt
3 tablespoons plus 1 teaspoon vegetable oil
1/4 cup honey
1/4 cup firmly packed light brown sugar
1 teaspoon pure vanilla extract
1/3 cup whole almonds
1/3 cup whole pecans
1/3 cup raisins
1/3 cup dried cranberries
Preheat the oven to 325 degrees F. Line a baking sheet with parchment paper.
In a large bowl, toss the oats with the cinnamon and salt.
In a medium bowl, stir together the oil, honey, brown sugar, and vanilla. Whisk until completely combined.
Pour the honey mixture over the oats mixture and use your hands to combine them: Gather up some of the mixture in each hand and make a fist. Repeat until all of the oats are coated with the honey mixture.
Pour the mixture onto the prepared baking sheet. Spread it out evenly, but leave a few clumps here and there for texture.
Bake for 10 minutes, then remove from the oven and use a metal spatula to lift and flip the granola. Sprinkle the almonds over the granola and return the baking sheet to the oven.
Bake for 5 minutes, then remove from the oven and use a metal spatula to lift and flip the granola. Sprinkle the pecans over the granola and return the baking sheet to the oven.
Bake for 10 minutes, then remove from the oven. Let cool completely. Sprinkle the raisins and cranberries over the granola and store in an airtight container for up to 1 week.
