What Pans to Use For Baking
There are a few different pans that we have tested this recipe with.
A square 8-inch cake pan is how we first made this recipe. We have been making them in that size pan for years.
We have also made these in a brownie pan. This way makes the cookie bars thinner and we can get more pieces out of a batch, which is perfect for larger families or gatherings.
Our newest and favourite way to make these is using silicone pans that are 11 inches by 5 inches. We get two pans with one batch, and we cut them into strips. The strips are also great for dipping in milk, melted chocolate or peanut butter.
Serving and Storing Reese’s Pieces Cookie Bars
These cookie bars make a great snack or dessert. We cut them into squares or strips before serving.
Cut Reese’s Pieces Cookie bars into squares and top with ice cream and a drizzle of chocolate syrup for a dessert that is perfect for a BBQ.
Any leftover cookie bars should be stored in an airtight container at room temperature. They will stay fresh this way for up to 3 days.
Can You Freeze Reese’s Pieces Cookie Bars?
Absolutely! These bars freeze well for up to three months when wrapped in parchment or plastic wrap, then placed in a freezer safe container.
Thaw the bars at room temperature before serving.
