The recipe is "Chewy PB Cookies"
1/2 cup Splenda, 2 Tbsps. Splenda, 1/2 cup oat flour, 1 tsp. baking soda, 1/2 tsp. baking powder, 1/2 cup butter, 1 cup natural creamy peanut butter, 3 eggs, 1/2 cup heavy cream, 1 1/2 tsps. vanilla extract, 2 Tbsps. liquid lecithin.
Given the vivid descriptions of how messy liquid lecithin is, I may eliminate this ingredient, or add a few teaspoons of the granules. The cookies may not be as chewy, but if they're pb, I'm sure I'll survive. :-) Thanks for all your advice.
