Mix in JUST Egg: Add the JUST Egg and vanilla gradually, allowing the liquid to fully incorporate. Mix on medium-speed until light, fluffy, and even in texture.
Fold in flour, oats, and chocolate: Add flour and oats. Mix until just until incorporated. Fold in the chocolate chips.
Scoop and bake: Scoop 2 oz (~¼ cup) portions of dough onto a baking sheet and bake for 10-13 minutes at 325°F (convection) or 350°F (conventional). Let cool on the baking sheet for about 5 minutes, then transfer to a cooling rack.
