1. Preheat the oven to 350°F and line an 8-inch round cake pan with parchment paper.
2. While the oven heats up, prepare the coffee cake: whisk together the eggs in a large bowl then add in the remaining wet ingredients and mix well. Next add in all of the dry ingredients and mix until the batter is smooth. Set aside.
3. While the batter rests, prepare the streusel: add all of the streusel ingredients (except for the chocolate chips) to a medium sized bowl and mix well.
4. Add half of the coffee cake batter to the bottom of the lined cake pan and smooth it out. Top the batter with half of the streusel and half of the chocolate chips. Repeat with the remaining batter, streusel, and chocolate chips.
5. Place the coffee cake in the oven and bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean. Once baked, remove from the oven and let it cool in the pan.

Glaze

1. While cake cools, heat 1 tbsp coconut butter in the microwave or on the stovetop until warm and runny. Remove from the heat and stir in 1 tsp water and 1 tsp pure maple syrup. Mix until smooth, adding additional water and maple syrup as needed to reach the right consistency.
2. Once the coffee cake has cooled, remove from the pan and drizzle with the glaze then slice and serve!
3. Optional: Substitute glaze with drizzled melted chocolate
