In a large bowl, stir together the oats, honey, and peanut butter until fully combined.
Use a silicone mini muffin tin or line a regular mini muffin tin with paper liners. Scoop a small amount of the oat mixture into each muffin cup. Press it down firmly with a spoon or your fingers to create a solid base. (You probably will not use all the oat mixture).
Spoon a small dollop of yogurt onto each granola base.
Top with sprinkles, fruit, granola, or mini chocolate chips for extra fun!
Place the muffin tin in the freezer for at least 1-2 hours, or until the bites are completely set.
Pop them out of the muffin tin and serve for a refreshing snack!
