Ok so they aren't chocolate-covered, but they taste amazingly decadent even though they have less sugar than most cookies. The cocoa powder adds an amazing difference to your grandmother's oatmeal raisin cookie. You'll never look at them the same again.
In a heavy saucepan, add butter, cocoa powder, and 1/2 cup of the chocolate chips, reserving the rest for later. Melt them together over low heat, stirring occasionally. When mostly melted, remove from the heat.
In a bowl, mix together the eggs and sugars. Beat for one minute once they're combined. Turn the mixer down and slowly pour in the chocolate mixture. Add vanilla and mix to combine.
3 eggs, 1/4 cup sugar, 1/4 cup brown sugar, 2 teaspoons vanilla extract
Add baking powder and salt and mix again. Add oats in two batches, stirring between additions.
Add the flour and stir until just combined. Add the remaining 3/4 cups of chocolate chips and the raisins and stir gently to distribute.
1 cup flour, 2 1/2 cups raisins
Use a cookie scoop or tablespoon to drop cookies onto sil pat covered (or greased) baking sheet.
Bake 14-16 minutes until cookies are just set and cracks start to appear in the tops of the cookies.
Let cool on the baking sheet for 10 minutes before removing to a cooling rack to complete the cooling process. Store in an airtight container on counter for 3-5 days.
