Preheat oven to 375°F. Line 2 baking sheets with parchment paper.
Beat butter and sugar until light and fluffy. Add the egg replacer mixture and vanilla. Beat for a minute.
In a small bowl, combine flour, baking powder, salt and baking soda.
Stir in the flour mixture into the butter mixture and beat until it comes together as a dough.
Fold the oats, cranberries, orange zest and chocolate chips. Mix well to evenly combine everything.
Using a small scoop, drop the dough onto the prepared baking sheet about 2" apart. Flatten them lightly.
Bake for 14~18 minutes or until the cookies are set and golden brown on the bottom. Remove onto a wire rack to cool completely.
