In a medium mixing bowl, combine 1 cup of creamy peanut butter and 1/4 cup of maple syrup. Mix until smooth and creamy.

Add 1 1/2 cups of old-fashioned rolled oats to the mixture and stir until well combined.

Scoop approximately 2 tablespoons of the oat mixture into each mold and press down firmly to create a compact layer.

Top each cup with a dollop of peanut butter or mix in protein powder to the remaining mixture.

Transfer the molds to the freezer and let them set for 20 minutes.

In a microwave-safe bowl, combine 1/2 cup of chocolate chips with a drizzle of neutral oil and heat until melted.

Drizzle the melted chocolate over each cup, covering generously.

Place the cups back in the freezer for another 20 minutes to harden the chocolate.

Gently remove the cups from the molds and sprinkle flaky sea salt on top if desired.
