Grease the inside of the slow cooker.

In a blender, combine the eggs, butter, applesauce, sugars, Bisquick mix, vanilla and cocoa powder. Cover and blend on high until smooth, about 1 to 2 minutes. Scrape down sides of blender occasionally if necessary. (If you prefer, beat all the ingredients with a mixer until smooth.)

Pour batter into the slow cooker. Sprinkle with chopped nuts.

Place 3 to 4 layers of paper towels over the cooker and Cover. (This will prevent condensation the accumulates in the lid from dripping back into your impossible chocolate brownie pie.)

Place the Cover over the paper towels. Cook on HIGH for 3 to 4 hours or until a knife inserted in the center comes out clean.

Turn off the slow cooker and remove the cover.

Serve warm or cool.

Cut into 8 wedges.
