mix the chopped nuts in a small bowl with the cinnamon and honey, until well-coated.
in a skillet over medium-low heat, add your butter or coconut oil, and place your chopped nuts, cooking until fragrant. remove from pan and set aside and add the sliced apples to the pan.
cook the apples until soft, feel free to sprinkle with a bit of extra cinnamon as well. once softened, remove from pan and set aside to place on the cake.
once the cake is out of the oven, warm up the remaining 1 tbsp of honey in the microwave for 10 seconds, until liquid-y.
using a spatula, spread the liquid honey gently across the cake to allow the apples and nuts to stick better to the top of the cake.
now, place the apples in even rows across the cake (i was able to do four rows, six columns of apple slices). sprinkle the nuts atop everything.
allow the cake to cool completely before slicing, using the apple slices as a guide of where to slice (i.e., every two apple slices = one piece of cake!). serve warm or cold.
