Had to add more goat milk powder as it was too runny and wouldn’t hold with original amount? 3 eggs wasn’t enough to split into 1/2 cup, likely why they flattened out. Definitely need to whisk the eggs more. Took 16 min to bake, took out and added butter and baked for 1-2 min more. Not a fan of goat milk powder taste, will try again with whole milk powder.
