Variation tip: Try to whisk in a teaspoon or two of vanilla extract to the wet ingredients for even more flavor.
Alternate ingredient:Different Chips such as chocolate chips, peanut butter chips, or even mint chips.
Alternate cooking method tip: Try making this recipe in the air fryer. Especially if you only want a few fresh, hot cookies. The first batch should only take about 8 minutes.
Add Spice: Try using a little chili powder or chipotle to taste for some heat.
Use Cocoa Flavorings: Try a little chopped mint candies, a drizzle of caramel or some espresso powder.
