Ingredients

Cookies

  • 1 cup (164 g) white chocolate chips
  • 2 tbsp (30 ml) lemon juice (strained, no pulp)
  • 2 tsp lemon zest (loosely measured, mostly dry)
  • 1/2 cup + 2 tbsp (57 g) quick oats

Instructions

  1. Prepare baking surface: Line a large cookie sheet with parchment paper to ensure easy removal of cookies after setting.
  2. Melt white chocolate: Place white chocolate chips in a large microwave-safe bowl. Heat in 15 to 30 second intervals, stirring in between, until the chocolate is fully melted and smooth. Alternatively, melt using a double boiler on the stovetop.
  3. Add lemon juice: Using a whisk, stir in the strained lemon juice until completely incorporated and the mixture becomes uniform and smooth.
  4. Combine zest and oats: Switch to a spatula and fold in lemon zest and quick oats thoroughly until evenly mixed, forming a thick batter.
  5. Scoop and shape cookies: Using a 1-tablespoon cookie scoop, portion the batter onto the prepared cookie sheet about 2 inches apart. Flatten each scoop with the back of a spoon or your fingers to about 1/4 inch thick and smooth edges as desired. Cookies will hold their shape without spreading.
  6. Garnish and chill: Optionally, sprinkle extra lemon zest on top of each cookie for added flavor and color. Place the cookie sheet in the refrigerator and chill for 30 minutes to 1 hour, until cookies are firm and peel easily off the parchment.
  7. Serve: Let cookies sit at room temperature for 10-15 minutes before eating for a softer texture, or enjoy them cold straight from the fridge. Store leftovers in an airtight container in the refrigerator or freezer.

Notes

  • One large lemon typically provides enough juice and zest for this recipe; you might have some leftover juice or zest.
  • To measure lemon zest, ensure it is dry and loosely packed into the measuring spoon without pressing down.
  • Strain lemon juice to exclude pulp for accurate measurement and smoother cookie batter.
