Recipe Tips
Use Room Temperature Ingredients: Let your eggs and coconut oil sit out for about 10 minutes before mixing. This helps everything blend smoothly and prevents the dough from being too dry.
Don’t Overmix the Cookie Dough: When adding the flour, fold it in gently until just combined. Overmixing can make the cookies dense instead of soft and chewy.
Alternate Scoops for a True Marble Effect: When assembling the brookies, use a 3-tablespoon cookie scoop to alternate between brownie and cookie dough in the pan. This creates a beautiful marbled effect and ensures you get both flavors in every bite.
Let Them Cool Before Cutting: Brookies continue to set as they cool. Let them sit for at least 10 minutes before slicing to get clean, even squares.
Ingredient Swaps: Coconut Oil ? Swap for melted butter or a neutral oil like avocado oil. Coconut Sugar ? Use brown sugar or maple sugar for a similar deep, caramel-like sweetness. M&Ms ? Try dark chocolate chunks, white chocolate chips, or Reese’s Pieces for a different twist. Gluten-Free Flour ? Use regular all-purpose flour if you don’t need them to be gluten-free.
Room Temperature: Store in an airtight container for up to 4 days.
Refrigerator: Keep in the fridge for up to 1 week for extra chewiness.
Freezer: Freeze in an airtight container for up to 3 months. Let thaw at room temperature or microwave for 10-15 seconds for a warm, gooey texture.
