Preheat oven to 350°. Spray an 8 x 8" or 9 x 9" square pan with pan spray, then line with parchment paper. Set aside.

In large mixing bowl, combine first five ingredients. Add beaten eggs and melted butter, stir until dry ingredients are well incorporated and wet.

Spread batter into prepared pan(s), Bake for 30 – 35 minutes. Brownies are done when knife inserted into center comes out *almost* clean - don’t overbake them!

Let brownies cool to room temperature before removing from the pan and frosting with ganache:

Place half of the white chocolate in a heat safe bowl, set aside.

In a small saucepan, heat half of the heavy whipping cream to a boil, remove from heat.

Pour hot cream mixture into bowl of white chocolate chips. Let sit for 3-5 minutes.

Starting in the middle of the bowl, slowly start stirring the chocolate and cream until all of the chocolate is melted and the cream has disappeared into it – it should be smooth.

Allow to cool slightly, then spread over the brownies. Place in the fridge to chill while you prepare the next layer.

Place the remaining chips in the same bowl, measure remaining heavy cream into the same small pot.

Add enough yellow gel food colouring to BRIGHTLY colour the cream - remember, it’s being added to the white chocolate chips, which will dilute the colour a bit.

Bring to a boil, pour over the white chips, let it set, then stir, as you did with the first layer.

Spread yellow ganache over the set - or partially set - white layer, return to the fridge to fully set, before adding the milk chocolate layer.

Place the chocolate chips in a heat safe bowl, set aside.

In a small saucepan, heat the heavy whipping cream to a boil, remove from heat.

Pour hot cream mixture into bowl of milk chocolate chips. Let sit for 3-5 minutes.

Starting in the middle of the bowl, slowly start stirring the chocolate and cream until all of the chocolate is melted and the cream has disappeared into it – it should be smooth.

Allow to cool slightly, then spread over the yellow layer of the brownies. Place in the fridge to set completely before cutting.
