In a small bowl, combine the cinnamon and sugar for the topping. Set aside. Line a plate with paper towels and place a wire rack over a sheet pan. Set both aside.

Combine the flour, sugar, baking powder, and salt in a large bowl. Add the melted butter and warm milk and stir until a slightly sticky dough forms. Cover the bowl with a piece of plastic wrap and let rest for 10 minutes.

While the dough is resting, pour 2-3 inches of neutral oil (canola, vegetable, peanut, etc.) into a dutch oven or other heavy bottomed pot. Add an oil/candy thermometer to the side of the pot to monitor the temperature. Once it reaches 350 F, you're ready to fry the dough!

After the 10 minute rest, transfer the dough to a lightly floured work surface. Divide the dough into 4 portions and roll it in the flour so that it's lightly covered and easier to handle. Shape each dough piece into a oval/rounded rectangle, reminiscent of a beaver tail. Flatten it to about 1/4 inch thickness. It doesn't have to be perfect!

When the oil is at 350 F, place one beaver tail into the oil and fry for 1-2 minutes per side. Place the freshly fried dough on the paper towel lined plate. Once the excess oil has been absorbed, transfer the dough to the wire rack and sprinkle a few spoonfuls of the cinnamon sugar mixture on top of it. Repeat with remaining dough pieces.

You can either enjoy the beaver tails as is, or you can top with a drizzle of Nutella and/or slices of banana!
