Preheat your oven to 345°F (175°C).
In a large mixing bowl, combine the rolled oats with the salt and your choice of spice (apple pie spice, pumpkin pie spice, or cinnamon).
1 cup old-fashioned rolled oats, 1/4 teaspoon salt, 1 teaspoon apple pie/pumpkin pie spice, 0.5 cup chopped nuts/seeds/more rolled oats
Then add the mashed banana, peanut butter, maple syrup, and vanilla extract (if using). Stir until everything is well combined.
1 medium banana, 3 Tablespoons peanut butter, 2 Tablespoons maple syrup, 1 teaspoon vanilla extract
Scoop about 2-3 tablespoons of the oat mixture into each silicone muffin cup. Use the back of a spoon or your fingers to press the mixture firmly into the bottom and up the sides of each cup, forming a well in the center. This will create the "cup" shape that will hold the yogurt.Note: If you don't have a silicone muffin tin, first grease your muffin tray with some oil. Bake the granola cups in the preheated oven for 12-15 minutes, or until they are golden brown and the sides get crispy. Allow them to cool in the muffin tin before removing them.
Once the granola cups are completely cooled, remove them from the muffin tin.
Just before serving, fill each cup with about 1 Tablespoon of your favorite yogurt. Then top with the fruits and the optional nuts and seeds. Enjoy!
1/2 cup yogurt, fresh berries or any other fresh fruits, nuts or seeds
