In a separate bowl, add the flours and baking powder and whisk gently to sift them together.
Cut the cylinder into 4-inch sections and connect the end of each section to create a circle. This always brings me back to memories of helping my grandma in the kitchen... it was my job to roll the dough and make each donut :) If you have kids, this is a fun place to have them help! Place each doughnut on parchment paper and set aside.
Once the temperature is achieved, add one doughnut at a time (TIP: do not overfill the pot and stay very attentive as they cook extremely fast... in under 30 seconds), and as soon as the sides start to brown turn it over with tongs or a fork. Remove from the oil and place on a baking sheet lined with paper towels to let the excess oil drip off.
