Cream the vegan butter, peanut butter and brown sugar until well blended, no need for light and fluffy here~ about 1 minute on high speed.
Add the vanilla extract to the plant milk and then add only half of it slowly to the creaming mixture scraping the bottom and sides of the bowl often for an even mix. Reserve the other half for last
Sift the flour, egg replacer, baking soda and salt and then add it to the creaming mixture while blending on low until all incorporated.
With a #100 Scoop drop rounded scoops into each cavity.
Press the dough with your fingers so it spreads to the sides of each cavity
Bake for 12 minutes or when they are light golden brown
Allow to cool in the tins slightly then unmold onto a cooling rack, flip them over and then I like to press them slightly to make a bigger indent to fit more chocolate in the centers!
Once the cookies are cooled~ fill the sunken centers with vegan ganache and sprinkle with chopped peanuts
