In a medium saucepan over low heat, melt the butter.

Remove from heat and scatter 1 c. white chocolate chips over the butter. Do not stir.

Allow to sit for 2 minutes, then gently stir the chips and butter together until mostly combined. Set aside to cool to lukewarm, about 10 minutes.

Meanwhile, in a large bowl, whisk together flour, brown sugar, baking powder, and salt.

Add the eggs, vanilla, and white chocolate mixture to the flour mixture. Mix until just combined.

Fold in the remaining 1 c. white chocolate chips.

Spread into a greased 9x13-inch pan.

Sprinkle the batter with the candy corn, and do not even press them into the batter. As it bakes, they will sink significantly!!

Bake at 325 degrees for 20-25 minutes, or until edges are golden brown and a toothpick inserted near the center comes out clean.

Remove to a wire rack to cool completely, and cut into bars.

Drizzle with melted orange and yellow chocolate wafer melts, or white chocolate, if desired.
