Instructions
Streusel Topping
You'll want to make the streusel topping first so the butter can firm up while you make the muffins.
Combine everything but the butter in a small bowl and mix together.
Melt the butter then slowly drizzle it into the bowl with the dry ingredients while mixing very gently with a fork and breaking up any large chunks. (Tip: you just want to use the tip of the fork and do more of a fluffing motion. You're just looking to make lumps and not a paste.)
Once you've mixed in the butter, you'll still see a bit of white flour and that's ok. Don't over-mix. Place the streusel topping in the freezer while you prepare the muffin batter or at least 15 minutes.
Muffins
Pre-heat the oven to 425° and spray a muffin tin with non-stick spray or use muffin tin liners.
Add your butter to a large bowl and melt it in the microwave. Usually about 50-60 seconds then just stir to melt any solid bits.
Add the cold milk to the melted butter. (This also will help cool down the butter)
Add the vanilla, white sugar, brown sugar, and lastly, beat in 2 eggs.
Evenly sprinkle the flour over the top of the wet mixture. Then sprinkle in the baking powder, salt, cinnamon, and nutmeg.
Mix everything together just until you see no more white flour.
Peel your apples and throw away the core. Then dice into small cubes that are about ¼ to ½ inch. Add these to the muffin batter and fold in gently.
Scoop the batter into the muffin tin and fill each cup about ¾ of the way up.
Take the streusel topping from the freezer and use your hands to break up the butter pieces or any large chunks. Top each muffin with streusel.
Bake at 425° for 5 minutes. Then lower the temperature to 350° and bake for 13-15 minutes or until a toothpick comes out mostly clean with just a few crumbs on it.
Allow the muffins to cool for about 15 minutes then enjoy!
