In a mixing bowl, whisk together the whole-grain flour, baking powder, salt, and cinnamon. In a separate bowl, beat the egg with milk and honey until smooth. Combine wet and dry mixtures, stirring until just blended.

Preheat your griddle over medium heat for about 5 minutes. Lightly grease with butter or oil and pour 1/4 cup of batter per pancake. Cook for 2-3 minutes, then flip and cook another 2-3 minutes until golden brown.

In a larger skillet, melt butter over medium heat. Add sliced apples, cinnamon, and lemon juice. Sauté for about 5-7 minutes until apples are tender and caramelized.

Stack pancakes on a plate and top with warm, caramelized apples. Optional: add Greek yogurt or nuts for serving.
