In a medium mixing bowl, combine the Greek yogurt, honey, peanut butter, vanilla bean paste, mashed banana, and a pinch of salt. Stir until smooth and creamy. Fold in the lightly smashed strawberries.
Line a baking sheet or plate with parchment paper or silicone mat. Scoop the mixture into 15 portions, about 2 tablespoons each. Flatten slightly into discs about ½-inch thick.
Freeze for about 1 hour or until fully firm.
Melt the dark chocolate in the microwave at 50% power for 30-second intervals or using a double boiler, stirring until smooth. Stir in coconut oil if using.
Using forks or dipping tools, coat each frozen disc completely in chocolate. Let excess chocolate drip off before placing back onto the parchment or silicone lined tray.
Freeze an additional 5–10 minutes until the chocolate shell is fully set.
