Tips on how to make the perfect Reese’s Oreo Chocolate Beer Bars:

  • Using high quality cocoa in this recipe is key, as the chocolate flavor is front and center.
  • Make sure the ingredients are at room temperature before you start baking. Also, the oven should be pre-heated.
  • Make sure the cake is fully cooled before frosting it.
  • If the frosting is too thin, add more powdered sugar 1/4 cup at a time.
  • The firmness of the buttercream frosting depends on the amount of sugar to liquid ratio. If you want a firmer frosting, add more confectioner’s sugar. If you want a softer frosting, add more beer to it. Just do it gradually.
  • Use strong flavored beer for a more pronounced beer taste.

Do Oreo’s have eggs?

There are no eggs in Oreo. However, Oreo have milk as cross contact and therefore they are not suitable for vegans. Oreo products do not contain nut or nut traces.

How to freeze the Reese’s Oreo Chocolate Beer Bars?

If freezing a frosted cake, first place cake in the fridge, so the frosting isn’t too soft. Fully wrap cake in plastic wrap tightly. Next, wrap in aluminum foil or place it in freezer bags. Freeze for up to 3 months. Defrost before slicing.
