FAQ

Can I make these without the chocolate drizzle?

Yes, these bars are delicious on their own. The chocolate drizzle is optional and adds sweetness and visual appeal but isn't necessary for structure or flavor.

What if I don't have a food processor?

You can mix by hand in a large bowl, but chop the oats slightly first. Mix dry ingredients, then add wet ingredients and stir until mixture holds together.

How long do these bars keep?

Store at room temperature in an airtight container for up to 1 week. Place parchment paper between layers to prevent sticking, especially with chocolate drizzle.
