Step 1: Prepare the Base

In a bowl, combine:

• Greek yogurt
• Sweetener
• Vanilla extract

Stir until completely smooth and evenly sweetened.

Step 2: Spread the Yogurt

• Line a baking sheet with parchment paper.
• Spread the yogurt mixture evenly into a rectangle about ½ inch thick.
• Smooth the surface using a spatula.

Thickness matters:

• Thicker bark = creamier center
• Thinner bark = firmer bite

Step 3: Warm the Peanut Butter

• Microwave peanut butter for 15–20 seconds.
• Stir until smooth and slightly runny.

Drizzle across the yogurt surface.

Step 4: Create Swirls

Use a toothpick or knife to gently swirl peanut butter into the yogurt.

Avoid overmixing — you want defined ribbons.

Step 5: Melt the Chocolate

• Melt chocolate in 20-second intervals.
• Stir between each interval.

Drizzle across the top and swirl lightly again.

Step 6: Freeze

• Freeze for 3–4 hours.
• Ensure bark is completely solid before removing.

Step 7: Break Into Pieces

• Remove from freezer.
• Lift parchment paper.
• Break into shards using your hands or a knife.
