Melt chocolate chips in microwave for a minute, stirring after to see if chips have melted. If not, microwave in increments of 30 seconds until completely melted.
In a medium bowl, sift the flour, salt and baking soda until combined. Set aside.
In a separate bowl, add the eggs, sugar and oil and mix until combined for about 2 minutes. Add the water and the vanilla extract. Add to the dry mixture to the wet mixture and melted chocolate chips and stir for about 3 minutes until combined.
Stir in Nutella until well combined. Stir in the 1/2 cup of unmelted chocolate chips.
Pour into a parchment lined, or a greased foil-lined 8x8 square pan. This will help with taking the brownie dessert whole out of the pan. Bake for 35 minutes.
When finished, remove from oven and allow to cool completely in pan on a wire rack.
For Dipping Brownies into White Chocolate
Melt the white chocolate in a microwave safe bowl for 1 minute. Testing the chocolate to see if it is melted enough by swirling with a spoon. If not, microwave in increments of 10 seconds, not passing 30 seconds total.
Using a toothpick, add a bit of food colouring on the tip and swirl into the white chocolate.
Putting it Together
When brownies have cooled, remove the entire dessert from the pan and unto a parchment paper, or a covered surface.
Using a heart shaped cookie cutter, cut out heart brownies as close as possible to one another to maximise the amount of heart shaped brownies you can get.
Dip half of the brownie into the pink mixture and place on a wire rack to dry.
You can serve them as, or package in cellophane as a gift. Enjoy!
