Mini JUICI Apple Cake Loaves:
In a large bowl, whisk together flour, baking soda, baking powder, salt, and pumpkin pie spice. Next add your softened butter and mix with a hand mixer until well-combined and granulated. Turning the mixer on low, add one egg at a time, followed by vanilla. Gently toss in diced apples and stir together with a wooden spoon or spatula (or even your hands if you’re ok with getting a little messy!) Make sure the apples are spread through out the dough evenly. The batter will be very thick.
Preheat the oven to 425 degrees and spray your mini loaf pan evenly. Scoop your mixture into each opening so that it is about 2/3 of the way filled. Leaving a little room to top with the crumble. These will slightly rise, but not too much.
Cinnamon Spiced Streusel Crumble:
In a small bowl, combine flour, brown sugar, pumpkin pie spice, and butter and mix together with a spoon until small crumbles begin to form. Top your batter with crumbles so that it covers the entire mixture well, and pack it in gently. Place in oven for about 6 minutes on 425 degrees, then decrease temperatures to 350 degrees for another 18-20 minutes. A fork or tooth pick should easily come out of your cake loaves without any sticky residue.
Cinnamon Vanilla Glaze:
Whisk together confectioners sugar, vanilla, whole milk and cinnamon and drizzle over mini loaves once they have cooled for about 15-20 minutes.
