In a blender, blend ½ cup oats, milk, 1 tablespoon maple syrup, vanilla, salt, and optional yogurt until mostly smooth.
Stir in remaining oats and chia seeds.
Spoon peanut butter decoratively inside two glasses or jars.
Divide oat mixture evenly between glasses.
Cover and refrigerate for at least 4 hours or overnight.
Combine remaining 2 tablespoons maple syrup and peanuts in a small skillet.
Cook over low heat, stirring often, until the maple syrup coats the peanuts and disappears from the pan.
Pour mixture onto a piece of parchment paper and set aside until crisp and cool. Store in an airtight container until ready to use.
When the oats are ready, top with candied peanuts, and sliced bananas, strawberries, an additional drizzle of peanut butter, and a sprinkling of chia seeds, if desired. Serve immediately.
