Slice the pears into long pieces. Preheat a medium size pan and put a piece of butter in it. Add the pear pieces to the pen, add sugar and the ground cinnamon. Cook over medium heat for about 5 minutes stirring occasionally until the pears are softened but not mushed.
In a stand mixer bowl combine the eggs, sugar, salt and vanilla extract. Beat them together for about 5 minutes.
Reduce the speed of your mixer and slowly add the milk. Then slowly add the vegetable oil and mix for another 20 seconds. Next, sift in the flour and the baking powder. Using a whisk attachment, mix the cake batter for 10-15 seconds on low speed. Then using a spatula, mix it again to make sure no dry flour is left.
Sprinkle with almonds and bake at 350°F degrees (180°C) for 40-45 minutes. Check the readiness of the cake with a wooden skewer or toothpick. The skewer inserted into the cake should come out dry.
Cover the cake with the plate and turn it upside down. Remove the baking dish and the parchment paper. Cover the cake with a plate again and turn it upside down one more time.
