Preheat the oven to 350°F. Line an 8x8 baking pan with parchment paper.
In a large bowl, whisk together the oil and sugar until the sugar dissolves. Beat the eggs and vanilla until well combined.
Add the cocoa powder, flour and salt and stir until thoroughly combined. Fold in the chocolate chips.
Pour the batter into the prepared pan and use a spatula to smooth the top. Bake for 20 to 25 minutes, or until a toothpick comes out with only a few crumbs. It’s better to under bake the brownies than to overbake them.
Allow to cool completely for at least 30 minutes on a wire rack.
Use a heart shaped stencil to cut the brownies into heart shapes. Add sprinkles if desired. Store the rest of the pieces for snacking.
