How to Make No Bake Cornflake Cookies

I’ve made a quick video to show you all the steps in this recipe but if watching a video isn’t for you, keep scrolling for the written directions. 

These steps will take you from start to finish through this recipe. They are quick and easy to make in just 6 steps. 

1. Melt the Chips

Place the butterscotch chips into a large mixing bowl that is microwave safe. 

Microwave at one-minute intervals, stirring after each minute until the chips are melted. 

Be careful not to overheat the chips, they will turn grainy and be ruined if you overheat them. 

2. Add Peanut Butter

Once the butterscotch chips are melted, add the peanut butter to the bowl and mix the peanut butter into the chips. 

3. Add Cornflakes

Measure the cornflakes in a separate bowl. Once the peanut butter is mixed in well. Add the corn flakes and fold them in. You want each cornflake coated so the cookies will stick together. 

4. Drop Cookies onto Prepare Sheet Pan

Line a sheet tray with wax paper or with a silicone sheet pan liner. Then drop cookie dough by teaspoonful onto the wax paper in small clusters. 

5. Leave to Set

Let the cookie sheet sit at room temperature until the cookies are set. 

If you want to quickly set them up, you can move the baking sheet to the refrigerator to cool them more quickly. Great for those times when you need your cookies now!

6. Remove cookies from Lined Sheet Pan

Once the cookies are set, remove them from the sheet pan and place in an airtight container for storage.

If you love chocolate you can add a few mini chocolate chips to the dry ingredients before stirring them into the butterscotch mixture. This will add a bit of chocolate flavor to the cookies. Remove 1/2 cup of cornflakes and replace them with mini chocolate chips.

Don’t want to add chocolate chips but want to add chocolate flavor? After the cookies are set, you can melt 1/2 cup of chocolate chips and then drizzle it over your set up cookies. It adds even more flavor to them with a bit of chocolate on each cookie. 

If you love dried fruit, you can add dry fruit to the dry ingredients before mixing with butterscotch mixture. Use 4.5 cups of cornflakes and 1/2 cup of dried fruit instead. 

If you love marshmallows you can substitute 1 cup or cornflakes with 1 cup of mini marshmallows in the recipe. Just add them to the dry ingredients and stir to mix well. Before adding it to the butterscotch peanut butter mixture.
