How to Make No-Bake Chocolate Oatmeal Cookies

This simple recipe for no-bake chocolate oatmeal cookies is ready to enjoy in less than 30 minutes!
When my boys were toddlers, our neighbor Rebekah, who lives on a Mennonite dairy farm up the road from us, started helping me as a babysitter. Rebekah’s mom has a stand at our local farmers market, where she sells fresh vegetables from the garden, homemade jams and sauces, and a wide array of baked goods like cookies and breads. Needless to say, we have been the lucky recipients of many of Rebekah’s treats over the years—including these No-Bake Chocolate Oatmeal Cookies!
Her no-bake cookies quickly became my boys’ favorite dessert, so Rebekah would make them for special occasions (like the kids’ birthdays), as well as for fun afternoon snacks. Her original recipe included peanut butter, but I tweaked the recipe to create an equally delicious nut-free version.
No-Bake Chocolate Oatmeal Cookies Recipe
This recipe yields approximately 36 cookies.
Ingredients
- 1/2 cup (1 stick) butter
- 1/2 cup milk (I use 2% milk)
- 2 cups granulated sugar
- 1/3 cup unsweetened cocoa powder
- 1 teaspoon vanilla extract
- 1/2 teaspoon salt
- 4 cups quick-cooking oats
Directions
Step 1: Prepare baking sheet
Line a large baking sheet with parchment or a silicone mat and set aside. You’ll want the tray ready to go as soon as your cookie mixture is combined!
Step 2: Boil chocolate mixture
Combine butter, milk, sugar, cocoa powder, vanilla extract and salt in a large saucepan. Bring to a boil, whisking regularly. Continue whisking and allow the mixture to boil for about 2 minutes. Remove from the heat.
Step 3: Add oats
Stir the oats into the chocolate mixture until completely combined.
Step 4: Drop onto baking sheet
Use a spoon or dough scoop to drop the oat mixture onto the prepared baking sheet. Work quickly, because the chocolate will start to set right away.
Step 5: Chill
Place the baking sheet in the refrigerator and allow the cookies to chill for about 10-15 minutes, or until firm.
Once the cookies are cool and set, package them in an airtight container. The cookies will stay fresh at room temperature for up to 1 week, or in the refrigerator for up to 2 weeks.
Tips for Making No-Bake Chocolate Oatmeal Cookies
Don’t undercook the chocolate mixture
If you don’t cook it enough, the sugar hasn’t dissolved and won’t set. You’ll end up with gooey no-bake chocolate oatmeal cookies! Be careful, though—if you cook them too long, the sugar overcooks and the cookies will set hard as rocks. I find a low simmer for 2 minutes does the trick.
Use quick-cooking oats
I do not recommend substituting with old-fashioned rolled oats or steel cut oats.
Add coconut
Make No-Bake Chocolate Oatmeal Cookies with Coconut by reducing the quick oats to 3 cups and adding 1 cup of sweetened shredded coconut.
Stir in dried fruit
Add dried fruit to the cookies by reducing the quick oats to 3 cups and adding 1 cup of raisins, dried cranberries, dried apricot or other similar mix-ins.
Top with flaky sea salt
If you like a sweet-and-salty contrast, sprinkle the tops of the cookies with flakes of sea salt before the cookies set.
Freeze leftover cookies
To freeze, place the cookies on a baking sheet and chill in the freezer for 2 hours. Once frozen, transfer the cookies to an airtight container or a large resealable plastic freezer bag. The no-bake cookies will keep in the freezer for up to 3 months.
