These no-bake peanut butter squares are a must-try treat for peanut butter lovers. These are a perfect, easy addition to fill out your cookie trays and dessert tables.
In a saucepan over medium heat, combine the sugar, butter, and milk. Slowly bring the mixture up to a boil and continue boiling for one minute.
Remove the saucepan from heat and stir in the peanut butter and the vanilla. Continue stirring until you have a smooth, even mixture.
Add in the oatmeal and stir until everything is well-coated.
Transfer the mixture to a baking pan lined with parchment paper. A medium loaf pan will result in thicker squares. An 8x8 baking dish will result in thinner squares. Smooth the top of the bars with the back of a tablespoon to create an even surface.
Chill the squares in the refrigerator for at least an hour or overnight. When the bars have set, lift them out of the baking dish and slice them into even squares.
Prepare the glaze: Heat the peanut butter in the microwave for about 20-30 seconds, then add in the confectioner's sugar and the vanilla. Stir until you have a smooth glaze for drizzling and all the lumps are removed. If the glaze is too thick, add a few drops of milk. Drizzle the glaze over the squares, then transfer them to the fridge to chill until the glaze is set.
