Tools You’ll Need
- Microwave-safe bowl – Melts the chocolate without a fuss.

- Parchment paper – Stops the cookies from sticking while they set.

Step-by-Step Instructions for 3-Ingredient No-Bake Lemon Oatmeal Cookies
Step 1: Prep Your Space
Line a baking sheet or large plate with parchment paper—keeps the cookies from sticking later. Set it aside where it’ll fit in your fridge.
Step 2: Measure the Chocolate
Dump the 1 cup white chocolate chips into a microwave-safe bowl—no need to be fancy, just get ‘em in there. This is your cookie glue.
Step 3: Melt the Chocolate
Microwave the chips on medium power for 30 seconds—stir with a spatula, then zap again in 15-second bursts ‘til it’s smooth and melted. Don’t overdo it—burnt chocolate’s a bummer.
Step 4: Add Lemon Zest and Juice
Stir in the 2 tsp lemon zest and 2 tbsp lemon juice—mix ‘til it’s all blended and smells zesty. It’ll thin out a bit, but that’s fine—keeps it workable.
Step 5: Mix in Vanilla (If Using)
If you’re going for it, add the 1/4 tsp vanilla extract—stir it in quick to give a little extra flavor. Totally optional, but it’s a nice touch.
Step 6: Stir in the Oats
Toss in the 2/3 cup quick oats (10 tbsp)—mix ‘til everything’s coated and you’ve got a thick, sticky dough. Make sure the oats are even—no dry clumps.
Step 7: Shape the Cookies
Scoop about 1 tbsp of the mix per cookie—roll into balls or flatten into discs with your hands or a spoon. Place ‘em on the parchment-lined sheet, spacing ‘em an inch apart—makes about 10-12 cookies.
Step 8: Chill and Serve
Pop the sheet into the fridge—let ‘em chill for 20-30 minutes ‘til they’re firm and set. Pull ‘em out, peel ‘em off the parchment, and enjoy—store extras in the fridge!
Storage and Serving
Store in an airtight container in the fridge for up to a week, or freeze for up to a month. Serve chilled or let ‘em sit out a minute for a softer bite—perfect with tea or as a quick snack.
Tips for Success
- Use quick oats—they soak up the mix better than old-fashioned.
- Melt chocolate slowly—high heat makes it seize up.
- Fresh lemon juice and zest beat bottled for flavor.
- Chill fully—warm cookies fall apart.
Substitutes and Variations
- Swap white chocolate for sugar-free chips if you’re cutting sweets.
- Try almond extract instead of vanilla for nuttiness.
- Add a few crushed nuts for crunch.
