Tips
Use natural peanut butter with minimal ingredients to avoid excess oil affecting texture; stir before measuring if separated.
Microwave chocolate in short intervals to prevent seizing; residual heat continues melting after removal from microwave.
Press the oat mixture firmly into corners for even thickness and cleaner cuts when chilled completely.

FAQ
Can I make these nut-free?
Substitute almond, sunflower, or tahini butter for peanut butter in equal amounts. Ensure all chocolate and candy are processed in nut-free facilities if needed for severe allergies.
How long do these keep in the refrigerator?
Store covered in an airtight container for up to 5 days. They firm slightly as they age but remain chewy. Freezer storage extends shelf life to 1 month when wrapped individually.
What if I don't have vanilla protein powder?
Use unflavored protein powder in equal amount, though flavor will be less sweet. Alternatively, omit protein powder and add 2 tablespoons extra oats for similar texture.
