Make the Homemade Granola
Preheat oven to 325°F (165°C). Line a baking sheet with parchment paper.
In a bowl, combine rolled oats, melted butter, brown sugar, cinnamon, and salt. Stir until every oat is evenly coated. Add coconut flakes and nuts if using; stir to combine.
Spread the mixture in an even, single layer on the prepared baking sheet.
Bake 20–25 minutes, stirring halfway through, until golden brown and fragrant. Watch closely in the last few minutes — granola can go from golden to burnt quickly.
Remove from the oven; let cool completely on the baking sheet without stirring. It will crisp up as it cools. Once cool, stir in dried cranberries or raisins if using.
Store in an airtight container at room temperature up to 2 weeks.
Prep the Berries
Wash and dry all berries thoroughly. Hull and slice strawberries into bite-sized pieces. If desired, toss berries with 1 tsp honey or maple syrup for extra sweetness. Set aside.
Sweeten the Yogurt
In a bowl, stir Greek yogurt with honey or maple syrup and vanilla extract until smooth. Taste and adjust sweetness to your preference.
Assemble the Parfaits
Choose clear mason jars or stemless wine glasses for the best visual presentation.
Start with a layer of granola at the bottom of each jar.
Add a generous layer of Greek yogurt on top.
Add a layer of mixed fresh berries.
Repeat: another layer of yogurt, then another layer of berries.
Finish with a final sprinkle of granola, a drizzle of honey, and a fresh mint sprig.
Serve immediately for maximum crunch, or refrigerate (granola stored separately) for meal prep.
