Step 1

Place chocolate chips, evaporated milk, and coconut oil in a medium-sized, microwave-safe bowl.

Step 2

Microwave on high for approximately 1 1/2 minutes (the exact timing can vary slightly depending on the power and wattage of your microwave).

Step 3

Stir until completely smooth and well-incorporated. (Do not microwave again; just use the heat from the chocolate to continue to melt the other chips.)

Step 4

Once the chocolate mixture is smooth, stir in any optional mix-ins that you'd like.

Step 5

Pour mixture into an ungreased 8x8" pan (or an 11x7" pan for thinner fudge that's easier to cut into shapes with cookie cutters). Smooth the top and tap or gently shake pan to level the mixture.

Step 6

Refrigerate until solid.
