Start by cooking your chicken. I cut my chicken into chunks and then place in a pot with water before bringing to a boil. Check the chicken after 30 minutes and cook until fully cooked. Once cooked cut/shred up your chicken and set aside.
Cut up all your veggies and set them aside.
In a large pot (you can use a dutch oven, I didn't) melt butter over medium-high heat.
Add onion, carrots and celery. Cook for 5 minutes, until the veggies become soft. Then add garlic and cook for 1 minute.
Add flour and stir to combine. Cook for another minute.
Add in chicken stock and slowly add the evaporated milk while stirring the pot. Bring to a boil and then add chicken, thyme, pepper and salt. Let it all simmer, uncovered, while making the dumplings.
In a large bowl, whisk together flour and baking powder. Make a hole in the center of the flour mixture and pour the milk and butter into the center of it.
Stir together until the dough ball forms. If your dough is too dry, add an extra tablespoon of milk.
Using a tablespoon, make 1 inch balls to drop into your simmering pot. Place them away from each other and try to avoid placing the dumplings on top of one another.
Once all the dumplings have been added, gently press them down so the soup runs over just the tops of them.
Cover the pot with your lid and lower the heat to a low simmer.
Cook for 15-18 minutes. At 15 minutes gently stir the dumplings and then cut one dumpling in half to make sure they're cooked through. If they need the extra 2-3 minutes then leave them on.
