  • Press the Rice Krispie mixture into the prepared pan. Be careful not to heavily press or smash the Rice Krispie treats into the pan or else they will tough and dry.
  • Press the garnish/decorating candy over top. You may have to gently press the candy into the bars to get them to stay.

  • Melt the almond bark or melting wafers in the microwave according to the package directions. Place the melted chocolate into a sandwich Ziploc bag and snip the bottom corner off. Drizzle the melted chocolate over top the bars and immediately add the sprinkles and press the candy eyeballs into the chocolate lines.

  • Cut into squares and serve!

Notes

Almond Bark : Use 2-3 squares of vanilla almond bark for the chocolate drizzle OR about 1/2 cup white melting wafers (Ghiradelli brand) or 1/2 cup white candy melts. Any of those options will work just fine. You can use white chocolate chips in a pinch, however, I suggest adding about 2 teaspoons of coconut oil or shortening to help it melt smoother and not seize up in the microwave.
Tip : To make pressing the gooey and sticky Rice Krispie treat mixture into the pan easier, spray a piece of parchment paper or wax paper with nonstick cooking spray (only one side of it) and then use it to lightly press the mixture into the pan. The side that has the spray on it should be touching the krispie treat. Keep your hands on the clean side. You can also use the underside of the butter wrapper to press the treats into the pan.
Low & Slow : Leave the heat on low when melting the butter and marshmallows. Low and slow is the key to the best Rice Krispies. Be sure to stir it frequently to avoid the marshmallows from burning and to keep them smooth.
Don't Press Hard : When pressing the treats into the pan it's so important to press them very gently and lightly. You never want to firmly press and compact them into the pan. Pressing too hard or firmly can result in chewier, denser, and drier rice krispie treats.
