Instructions
- Make your chai spice blend by mixing together cinnamon, cardamom, cloves, ginger, and coriander. Set aside.
- Prepare a round or square 8-inch pan with baking spray and/or parchment paper. Preheat your oven to 350 degrees F.
- Make your cake batter. Using a mixer, cream together room temp butter and granulated sugar for 3-5 minutes until lightened in color and fluffy. Add egg, egg yolk, and vanilla, and continue to beat on medium-high until emulsified–lightened in color and smooth in texture, about 5 minutes.
- In a separate mixing bowl, whisk together flour, baking powder, baking soda, and salt.
- With your mixer on low speed, add dry ingredient mix alternating with buttermilk (1/3 dry, 1/2 buttermilk, 1/3 dry, 1/2 buttermilk, 1/3 dry) mixing just until combined.
- Spread 1/2 of the cake batter into your prepared cake pan.
- Make your chai filling. Add melted butter, chai spice blend, brown sugar, flour, and salt in a mixing bowl and stir until combined. Pour/spread this mixture on top of your cake batter in the cake pan.
- Carefully spoon your remaining 1/2 cake batter on top of the chai spice filling, covering the filling completely. Even the top with an offset spatula.
- Make your chai crumb. In a medium mixing bowl, add flour, brown sugar, chai spice blend, and salt. Add cubed butter and massage with your hands until the butter is distributed in almond-sized crumbs. Add your tsp of water and mix with hands until the mixture resembles a crumble.
- Spoon your crumble evenly all over your cake batter.
- Bake at 350 degrees F for 50-55 minutes. Cake is finished when the crumble is golden brown and a toothpick inserted comes out clean with crumbs. Allow the cake to cool for at least 20 minutes before slicing and enjoying.
Notes
- If you prefer a more classic coffee cake flavor profile, you may sub 1 tbsp cinnamon for the chai spice blend.
- This coffee cake is best enjoyed the day of making. However, it will stay fresh for 2-3 days at room temperature in an airtight container.
