Start by making the dumplings. Combine 1 ¾ cup flour, ¾ tbsp baking powder, 1 tsp salt, 1 tsp garlic powder. Add in 1 and ¼ cup heavy cream and work through until a dough forms. Roll into 1 inch balls and allow to settle to room temperature while you begin your soup.
Cut chicken into 1 ½ inch slices. Heat dutch oven to medium-high heat. Drizzle with vegetable oil and add in the chicken. Cook for 3-4 minutes per side. Remove to cool on a plate lined with paper towels.
While the chicken is cooling, cook the chopped carrots and onions in the dutch oven until softened (use more oil if needed - just enough to coat the bottom). Add the garlic for the last minute of cooking.
Reduce heat to medium and add 7 tbsp butter. Once melted, whisk in the flour stirring constantly to prevent burning until it turns into a thick paste.
Add in 4 cups chicken broth, 4 cups beef broth, 1 ½ cups heavy cream, 2 bay leaves, thyme, 2 tsp garlic powder and 2 tsp onion powder. Bring to a simmer.
Add the frozen peas and cover for 10 minutes.
Remove lid and add in the dumplings one at a time to avoid splashing. Add lid and allow to cook for an additional 15 minutes.
Remove lid and allow to cool at least 10 minutes. The dumplings should be floating. Be sure to extract the bay leaves before serving! Enjoy!
