1/2 baked pumpkin pie (can be crust-less, you only use the filling)
Place oil in 12-inch nonstick skillet and heat over low heat for at least 10 minutes.
While skillet is heating, whisk together flour, sugar, salt and cinnamon in medium bowl;set aside.
In a separate medium bowl, whisk together milk and eggs. Add half of milk mixture to dry ingredients and whisk until smooth. Add butter and whisk until combined. Whisk in remaining milk mixture until smooth.
To make pumpkin pie filling, scoop the pie filling out of the crust and place in the bowl of a stand mixer fitted with the paddle attachment. Beat on medium speed until smooth, about 30 seconds; set aside. (Heat it in the microwave if desired)
Wipe out skillet using paper towel, leaving thin film of oil on bottom and sides. Increase heat to medium and let skillet heat for 1 minute. After 1 minute, test heat of skillet by placing 1 teaspoon batter in center and cook for 20 seconds. If mini crêpe is golden brown on bottom, skillet is properly heated; if it is too light or too dark, adjust heat accordingly and retest.
Pour ¼ cup batter into far side of pan and tilt and shake gently until batter evenly covers the bottom of pan. Cook crêpe without moving it until top surface is dry and crêpe starts to brown at edges, loosening crêpe from side of pan with rubber spatula, about 25 seconds. Gently slide spatula underneath edge of crêpe, grasp edge with fingertips, and flip crêpe. Cook until second side is lightly spotted, about 20 seconds. Transfer cooked crêpe to wire rack, spotted side is facing up. Return pan to heat and heat for 10 seconds before repeating with remaining batter. As crêpes are done, stack on wire rack.
Transfer stack of crêpes to large microwave-safe plate and invert second plate over crêpes. Microwave on high power until crêpes are warm, 30 to 45 seconds (45 to 60 seconds if crêpes have cooled completely). Remove top plate and wipe dry with paper towel. Spread 1/4 cup pumpkin pie filling in each crêpe and roll up. Sprinkle with confectioner’s sugar and serve immediately.
