In a medium bowl, mix the flour, baking powder, cinnamon, salt, and brown sugar.
In a separate bowl, whisk together the melted butter, egg yolk, milk, and vanilla.
Add the wet ingredients to the dry and stir until just combined.
Fold in the diced apple and chopped pecans.
Spoon the batter into a lightly buttered 10-ounce ramekin.
Make the Topping
In a small bowl, mix the streusel ingredients—flour, brown sugar, cinnamon, pecans, and softened butter—until crumbly. Sprinkle evenly over the batter.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Cool for 5 minutes before serving.
Notes
Read Through the Recipe: Review the full recipe and Ingredient Notes before starting. Everything you need is in the post, including helpful photos.
Use the Right Dish: A 10-ounce ramekin (4 inches wide, 1¾ inches tall) works best. A larger dish may bake too quickly; a smaller one may take longer.
Bake on a Rimmed Sheet: Place the ramekin on a rimmed baking sheet to catch any spills.
Don’t Overmix: Mix the batter just until combined to keep the muffin tender.
Measure Flour Correctly: Spoon flour into your measuring cup and level it off with a knife for accuracy.
If doubling the recipe, use two 10-ounce ramekins or one 5x5-inch baking dish.
