FAQs: Ingredients in 3 Ingredient Peanut Butter Cookies

Q: Can I use natural peanut butter for this recipe?
A: Absolutely! Just make sure to stir it well before using. Natural peanut butter tends to be oilier, so your cookies might spread a bit more. If the dough seems too soft, you can chill it for 15 minutes before baking.

Q: Can I substitute the sugar with a healthier alternative?
A: Yes! You can use coconut sugar, maple syrup, or honey, but keep in mind this will change the texture slightly. For liquid sweeteners, you might need to reduce the peanut butter by a tablespoon to balance the moisture.

Q: Why did my cookies turn out crumbly?
A: This usually happens if the dough was undermixed or if you used natural peanut butter that separated. Make sure to mix thoroughly until the dough is completely smooth. Adding an extra egg yolk can also help bind them better.

Q: Can I make these cookies vegan?
A: Definitely! Replace the egg with a flax egg (1 tbsp ground flaxseed + 3 tbsp water, let sit for 5 minutes) or use 1/4 cup applesauce. The texture will be slightly different but still delicious.

Q: How do I store these cookies?
A: Store in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months. They actually taste great straight from the freezer!

Q: Can I add chocolate chips or other mix-ins?
A: Of course! Fold in 1/2 cup of chocolate chips, chopped nuts, or even a sprinkle of sea salt before baking for extra flavor and texture.
