Sift or whisk the flour, baking powder, and salt together in a large mixing bowl. Whisk in the warm water, and four tablespoons of oil, then switch to a rubber spatula to mix until a soft dough forms.

Tip the dough out onto a clean counter and knead for 8-10 minutes until it becomes smooth and elastic. Form the dough into a ball, then place it into a large bowl. Cover with a clean kitchen towel and leave to rest in a warm place for 30 minutes.

Place the sugar and cinnamon in a medium bowl and stir to combine.

When the 30 minutes is up, divide the dough into 8 parts and roll each one into a ball. Flour your work surface and a rolling pin, and roll each dough ball into an 8-inch circle. Stack between pieces of parchment paper.

Fill a large, high-sided saute/frying pan with 3 cups of oil. Heat the oil to 350°F/180°C (use a food/candy thermometer to check). Prepare a plate or tray with some paper towels to remove excess oil.

When the oil has reached temperature, remove a dough circle from the parchment paper and carefully place it into the hot oil.
Fry on both sides for 45-60 seconds or until it is a light golden color. Remove from the oil and place onto the prepared paper towels to remove excess oil.

Place a fried buñuelo into the cinnamon sugar and lightly toss to coat. Serve and enjoy!
