Peanut Butter Playdough! At my house, this is in the regular rotation of fun activities requested. Easy to make. Delicious to eat. Fun for everyone.
All you need is: light corn syrup (dark works but requires more), creamy peanut butter, powdered sugar, and instant dry (powdered) milk. Mix equal parts of each ingredient (this batch was about a cup of each...).
It's really whatever texture you want it to be, so more peanut butter and/or corn syrup=a more moist dough. More powdered sugar and/or dry milk=drier, flakier dough. Moist is better for sculpting masterpieces like these lovely dinosaurs...:)
