Mix the oat flour, baking powder, salt, honey, egg, oat milk and 2 tablespoons of oil. Mix well until you obtain a homogeneous and thick dough.
Insert a skewer stick into each sausage and dry them with kitchen paper so that the mixture adheres better.
Coat the sausages in the oat mixture, making sure they are completely covered.
Fry the banderillas in the hot oil, turning occasionally, until golden brown and crispy, about 3-4 minutes.
Remove the banderillas from the oil and place them on absorbent paper to remove excess fat.
Serve the oatmeal banderillas hot, accompanied by mustard, ketchup or your favorite sauce.
