Preheat the oven to 350 degrees Fahrenheit.
Line an 8 inch baking pan with parchment paper and set aside.
Cream together the sugar and room temperature eggs with an electric mixer for 1 minute.
In a small bowl, combine the coconut oil and chocolate. Melt in the microwave using 30 second increments, stirring between each until melted.
Once done, beat in with the eggs, sugar and vanilla.
Beat in the peanut butter.
Sift in the almond flour, cocoa powder and salt.
Fold together until combined. Fold in the chocolate chips if using.
Add to the prepared pan and spread evenly. Add a few dollops of peanut butter on top and swirl with a knife or chopstick.
Add to the oven and bake for 20-25 minutes or until a toothpick comes out clean.
Let cool before slicing, then enjoy!
