In a large bowl, whisk together flour, brown sugar, baking powder, salt, and ground cinnamon.
Whisk in milk, applesauce, egg, vanilla, and maple syrup together in a separate bowl and then pour wet ingredients into the dry.
Stir together without overmixing
Once the apple is peeled and chopped into small pieces, gently fold them into the batter.
Prepare a large dutch oven for frying by adding avocado oil and heating the dutch oven to 350°F or medium heat. You’ll know the oil is hot enough when it starts to shimmer.
Scoop 1/4 cup of applesauce fritter batter into the hot oil. Use a large spoon to spread out the batter. Shape doesn’t really matter but i like to flatten mine out so that they fry evenly.
Fry for about 2 minutes and then carefully flip the fritters using a slotted spoon and fry for another 2 minutes or until the fritters are golden brown.
Remove fritters from the oil and place them onto a wire rack with a cookie sheet underneath to drain. You can also use paper towels to absorb the extra oil.
Prepare the glaze by whisking together powdered sugar, milk, and vanilla until smooth.
Once the fritters have cooled enough to touch, dip them into the glaze and place them on the cooling rack until the glaze is set.
