Creating Frozen Yogurt Peanut Butter Cups is straightforward. Follow these steps to make your own delicious treats:

1. Prepare the Muffin Tin: Line a muffin tin with paper liners or silicone molds for easy removal.
2. Mix the Yogurt: In a mixing bowl, combine Greek yogurt, honey or maple syrup, vanilla extract, and salt. Stir until smooth and well combined.
3. Fill the Molds: Spoon a layer of the yogurt mixture into each muffin cup, filling them about halfway.
4. Add Peanut Butter: In a separate bowl, mix peanut butter with a little honey or syrup if you prefer it sweeter. Spoon a dollop of peanut butter on top of the yogurt layer in each cup.
5. Top with Yogurt: Add more yogurt on top of the peanut butter layer, filling each cup to the brim.
6. Sprinkle Optional Toppings: If using, sprinkle mini chocolate chips, chopped nuts, or fruit pieces on top of the final yogurt layer.
7. Freeze: Place the muffin tin in the freezer for at least 2 hours, or until the cups are completely set.
