Line a sheet pan with parchment paper. This will later be used to cool the homemade granola.
Melt the butter in a medium-sized skillet over medium heat. Add the pecans, coconut flakes, sunflower seeds, and brown sugar substitute. Stir to coat all the ingredients in the melted butter.
Cook, stirring occasionally, until fragrant and toasted. This will take from 3 to 5 minutes.
Spread the granola evenly on the sheet pan. Allow to cool completely.
In a Medium mixing bowl stir together the yogurt and protein powder until smooth and well combined.
Layer 3 tablespoons of yogurt in the bottoms of six 8-ounce wide-mouth jars or cups. Add a sprinkle of granola to each jar, followed by 2 tablespoons of sliced strawberries and a heaping tablespoon of blueberries. Repeat the layer once more.
