Begin by melting the white chocolate chips along with the coconut oil in a microwave-safe bowl. Heat in short bursts of 10-15 seconds, stirring after each interval, until the mixture is smooth and glossy.

In a large mixing bowl, combine the protein powder, oats, cinnamon, and your choice of sweetener. Stir the mixture well until all ingredients are evenly dispersed.

Gradually pour the melted chocolate mixture into the dry ingredients, stirring continuously. Mix until the chocolate is fully incorporated and resembles a sticky dough.

Using your hands, scoop out portions of the mixture and roll them into bite-sized balls, about 1 inch in diameter. Place each ball on a baking sheet lined with parchment paper.

Transfer the baking sheet to the freezer. Chill them for 20-30 minutes until they are firm to the touch.

Melt a bit more white chocolate if desired, and drizzle it over the tops of the protein bites. Let the drizzled chocolate cool and harden before serving.
