Preheat the Oven: Preheat your oven to 350°F (175°C).
Make the Oat Cups: In a large bowl, combine the old-fashioned oats, peanut butter, and maple syrup. Mix until well combined. The mixture should be slightly sticky but not overly wet.
1 1/2 cups old-fashioned oats, 3/4 cup peanut butter, 3 Tablespoons maple syrup
Form the Oat Cups: Scoop the oat mixture evenly into 6 greased muffin cups. Press the mixture down gently using the bottom of a small glass or your fingers to form a little "cup" shape in each muffin cup.
Bake: Place the muffin tin in the preheated oven and bake for 12-15 minutes, or until the edges of the oat cups are golden and firm to the touch.
Cool: Let the oat cups cool completely in the muffin tin before removing them.
Assemble: Once the oat cups have cooled and are removed from the muffin tin, fill each cup with vanilla yogurt (about 1/4 cup per cup). Top the yogurt with fresh raspberries (or any berry of your choice) and a dollop of reserved peanut butter for extra flavor.
2 cups vanilla yogurt, Fresh raspberries
Serve: Serve immediately or refrigerate.
