Healthy donuts with spiced apple topping

Combine all donut dough ingredients (flour, greek yogurt, baking powder, cinnamon) and mix until completely combined. Using a rolling pin, flatten dough until it’s 1.5 inches thick. Using a cup, make a donut shape and poke a hole in the center. Repeat until all dough is used and place on a lined baking tray. For your crumble, place all ingredients (flour, brown sugar, sugar) in a bowl. Using your hands, mash together until a sand-like texture forms. Top the donuts with the crumble and bake at 375°F (190°C) for 25 minutes or until golden brown. In a medium skillet, heat your butter, diced apple, maple syrup, and an additional amount of cinnamon until apples are soft. Top your cooked donuts with the spiced apple mixture. Enjoy!
