In a small skillet over medium heat, melt 1 tbsp butter. Add diced apple, brown sugar, and 1/2 tsp cinnamon. Cook 5–7 minutes until tender and caramelized. Set aside to cool. 🍎
2️⃣ Make the Batter
In a mixing bowl, whisk together flour, sugar, baking powder, baking soda, cinnamon, and salt. 🥣
In a separate bowl, mix buttermilk, egg, melted butter, and vanilla. Pour the wet mixture into the dry ingredients and stir until just combined. 🥄
Gently fold in the cooled apple mixture. 🍏
3️⃣ Cook the Waffle Donuts
Preheat and lightly grease a waffle iron. Spoon batter into the center of each mold. Close and cook 3–4 minutes until golden brown and cooked through. Remove and cool on a wire rack. 🔥
Alternative: If you don’t have a waffle iron, heat a nonstick skillet over medium heat. Spoon batter into small rounds, press down gently, and cook 2–3 minutes per side until golden.
4️⃣ Prepare the Glaze
Whisk together powdered sugar, milk, and vanilla until smooth. Adjust thickness with more milk or powdered sugar if needed. 🍶
