In a large bowl, mix together the oats and Rice Krispies, and set aside.

In a saucepan or double boiler, melt the honey, peanut butter, and brown sugar.

Bring the mixture to a very slight boil, stirring frequently to dissolve the sugar.

Once dissolved, remove from heat and add the vanilla extract.

Pour the liquid mixture over the oats and Rice Krispies, and mix until everything is evenly coated.

Let it cool slightly, then add the sprinkles and chocolate chips. Mix well.

Press the mixture into a prepared 9 x 13-inch baking dish and allow it to sit in the freezer for about 30 minutes.

Meanwhile, melt the white baking chocolate.

Drizzle the melted white chocolate over the top of the granola and let it dry.

Once set, cut into 15 bars.
