In a regular mixing bowl, or your standing mixer, mix together on medium-low speed the 5 eggs, 250g pumpkin puree, and ¼ cup (55g) brown sugar , until well combined and turn off the mixer.
Once it's all combined, turn your mixer to low speed and slowly add the 2 ½ cups (750g) milk .
Next you will add the 5 cups (600g) einkorn flour , 2 tsp baking powder , 1 tsp baking soda , and 1 Tbsp pumpkin pie spice . Mix on medium-low speed. This will create a thick batter.
Using a large frying pan, set your heat to medium heat. You can use any non-stick substance, however I recommend butter for greasing the pan . Place about a ½ tablespoon of butter into the pan before adding the einkorn pumpkin pancake batter. I like to use a ¼ cup measuring cup and scoop them onto the pan.
Once bubbles begin to appear on the dough side (and before those cute little bubbles pop), flip the pancake and let it cook for 30-40 seconds on the other side before removing it from the pan.
Refresh the pan with butter regularly to prevent sticking while finishing up the batch.
Remove from heat and onto a serving plate!
