Peanut Butter S’mores Sandwich Cookies Recipe FAQs
What type of peanut butter should I use?
You can use smooth or crunchy peanut butter, depending on your texture preference. If you’re looking for a different nutty flavor, almond butter works beautifully as a substitute. Just ensure it’s creamy enough to blend well with the sugars and egg!
How should I store Peanut Butter S’mores Sandwich Cookies?
To keep your cookies fresh, place them in an airtight container at room temperature for up to 5 days. For a firmer texture, refrigerate them in a sealed container for about a week. If you want to save them for later, freeze the cookies in a single layer for up to 2 months!
Can I freeze Peanut Butter S’mores Sandwich Cookies?
Absolutely! To freeze, let the cookies cool completely, then layer them in a zipper bag or airtight container with parchment paper between layers to prevent sticking. When you’re ready to enjoy them, simply thaw at room temperature or microwave for a few seconds to warm them and soften the marshmallow filling.
I’m having trouble with my cookies spreading too much. What should I do?
If your cookies are spreading too much, make sure your dough is well-chilled before scooping it onto the baking sheet, as this will help them hold their shape. Also, keep an eye on the mixing process; overmixing can cause the texture to change, resulting in flatter cookies.
Are there any allergy considerations for this recipe?
Since these Peanut Butter S’mores Sandwich Cookies contain peanut butter, they are not suitable for individuals with nut allergies. For an allergy-friendly option, replace the peanut butter with a sunflower seed butter to keep them nut-free. Be cautious about any chocolate or marshmallows you use, as they may contain allergens as well.
Can I substitute the egg in this recipe?
Yes! You can use a flax egg as a vegan alternative by mixing 1 tablespoon of flaxseed meal with 2.5 tablespoons of water. Let it sit for about 5 minutes to thicken before adding it to the cookie mixture. This allows the cookies to bind similarly to how an egg would!
