Preheat oven to 350
Grease 13 x 9 x 2 glass baking dish
Melt chocolate. I use my microwave on 50% power, 1 min at a time, to melt chocolate. Be sure to use a reduced power or you may burn your chocolate. You can use a double boiler if you wish, I just find that method takes more time.
Add vegetable oil, sugar and eggs to your melted chocolate chips. Mix well with spoon or mixer.
Stir flour, baking soda, cocoa powder, and salt to separate bowl and add in OR use a sifter or fine strainer and add directly to chocolate mix. Mix well until all ingredients are combined.
Add chocolate chips and stir well.
Pour mixture into baking dish and spread evenly.
Bake in preheated oven for 30-35min
Serve warm!
