These homemade Mint Granola Bars are tastier than store-bought versions. They’re simple to make and have a soft, chewy texture that’s perfect for a quick breakfast or an on-the-go snack.

Granola bars are versatile — they can be a wholesome bite or a sweet treat. I often start with the same base used for caramel oatmeal bars to make baked granola bars that hold together well and stay chewy.
When my kids were younger they loved granola bars, so I experimented with flavors every week. After discovering an extra package of mint cookies in the pantry, I created these cookie-filled granola bars. They’re straightforward to prepare and bake in about 18–20 minutes.
Enjoy them plain for a simple snack or add a green and chocolate drizzle to dress them up for St. Patrick’s Day — both are delicious options.
