- Combine wet and dry ingredients just until combined.

Hi i would love to make these but I dont have a mixer can I do this by hamd. Also what is all purpose flour?
Hi Mags! Yes, you can make these by hand, but you’ll need some arm strength to mix quite a bit so the peanut butter, butter and sugars are very well combined.
Delicious! I baked it exactly as is except left out the chocolate chips.ย
350 for 20 minutes is the perfect temp and time.ย
These Reeseโs Pieces bars are delicious! Iโm adding them to the menu for my Halloween party. Thanks!
How much is 1 cup of Reese’s Pieces in grams? In my country we don’t measure with US cups.
Hi Sara – 1 cup Reese’s Pieces is approximately 200 g. I’ll update the recipe card since I also prefer measuring by weight!
Way too dry
