Prepare butter topping. In a bowl, beat the butter until creamy. Add the powdered sugar, and pumpkin spice and beat again. Set aside for serving.
In a large bowl, whisk together all the ingredients for the egg/milk mixture. Transfer to a casserole dish (easier to dredge the bread).
Submerge the bread slices into the egg mixture, covering both sides. Place bread on a platter. Continue with remaining bread slices.
Add butter and oil to a large skillet for frying. Amounts will vary depending on the size of the pan. Place about 2-3 bread slices in the skillet at a time.
Cook over med/high heat for about 2-3 minutes on per side, until bread is golden and crispy.
