FAQs

What if I don’t have quick oats?

Quick oats are ideal for the right texture, but you can pulse old-fashioned oats in a food processor for a similar effect.

Can I use natural peanut butter?

Yes, but make sure it’s well stirred and not too oily, as it may affect the consistency of the cookies.

Why didn’t my cookies set properly?

This usually happens if the mixture didn’t boil long enough. Make sure to boil for a full 1–2 minutes after it starts bubbling.

Can I make these cookies without cocoa powder?

You can, but they’ll lose their chocolate flavor. Try substituting with carob powder or skip it for a pure peanut butter version.

How long do these cookies last?

They last up to 5 days at room temperature or 3 months in the freezer.

Are these cookies gluten-free?

They can be if you use certified gluten-free oats.

Can I add toppings to these cookies?

Yes, press in mini chocolate chips, chopped nuts, or sprinkles before the cookies set.

Can I double the recipe?

Absolutely. Just make sure to work quickly when mixing and shaping to prevent the mixture from setting too early.

What’s the best way to portion these cookies?

A cookie scoop helps ensure even portions, but you can also use a tablespoon.

Can I make them vegan?

Yes, use plant-based butter and non-dairy milk to make a vegan version.
