Preheat oven to 350 degrees. Grease a 8” square pan and set aside.
Combine millet flour (or brown rice flour), Bob’s Gluten Free 1 to 1 Flour, almond flour or finely ground almond meal, tapioca starch, baking powder, baking soda, salt, cinnamon, nutmeg, and pumpkin pie spice in a medium size bowl.
In another bowl or stand mixer bowl, add honey, brown sugar, cane sugar, and oil. Combine on low speed for 30 seconds. Add the eggs and vanilla and mix on medium for three minutes more. Add the dry ingredients into the stand mixer bowl. Mix on medium until well combined.
Add the chopped apples and stir either by hand or in the mixer, with the setting on low speed for 20 seconds, or just until combined. Scrape the batter into the greased pan.
To make the topping, in a small bowl, stir together the almond flour, brown sugar, chopped pecans, and ½ teaspoon of cinnamon.
Sprinkle the topping gently on the top of the cake batter, topping evenly. Then add the butter pieces spread evenly across the cake top.
Bake at 350 degrees for 40-45 minutes. Check at 38 or 40 minutes with a toothpick poked into the center. Continue baking until toothpick comes out clean.
