Preheat oven to 350℉
Step 1: Make the streusel. In a medium mixing bowl, add melted butter, brown and white sugar, salt, and flour. Mix until combined and a crumbly texture is formed. Spread the mixture over the silicone molds leaving about 1/2 cup for later. Freeze molds for about 10 minutes.
Step 2: Make the cinnamon layer. In a small bowl, add brown sugar and cinnamon and stir to combine. Set aside.
Step 3: Make coffee cake. In a medium mixing bowl, add flour, baking soda, baking powder and salt and whisk together. In another bowl, add wet ingredients, apple sauce, vanilla, non-dairy milk and brown sugar and stir. Slowly mix the dry ingredients into the bowl of wet ingredients to combine. Careful not to over-mix.
Step 4: Pour 1/2 the cake mixture into the loaf pan lined with parchment paper. Then add the cinnamon layer, sprinkling it evenly over the cake. Next add your other 1/2 of the cake mixture.
Step 5: Add the streusel: Pour the extra streusel leftover from the molds onto the cake and add a touch of cinnamon sprinkled over top. Remove your silicone molds from the freezer and carefully pop out your graveyard decorations. Add them on top of the cake.
Step 6: Place the coffee cake in the oven and bake for 40-45 minutes. Remove from oven and let sit for 15 minutes.
