• In a small saucepan, reduce 1 ½ cups of apple cider over medium heat, mixing occasionally until it starts to boil (about 10 minutes). Once boiling, reduce the heat to low and allow the cider to cook for another 10 minutes. Once reduced, you will have a little more than ½ cup of apple cider. Place the reduced cider in the refrigerator until later.
• Preheat the oven to 350 degrees and line an 8x8-inch baking pan with parchment paper, creating a "handle" over the sides, and then non-stick spray.

Apple Spice Filling

• In a small bowl, whisk together the flour, brown sugar, apple pie spice, and salt. Set aside.

Apple Cider Cake

• In a medium-sized bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt. Set aside.
• In the bowl of an electric stand mixer using the paddle attachment, beat together the butter and brown sugar on med-high speed until combined and creamy (1-2 minutes). Add the egg on med-speed and mix until incorporated. Then mix in the yogurt, vanilla extract, and ½ cup of the reduced apple cider. Scrape down the sides of the bowl as needed.
• Add the flour mixture into the wet ingredients and mix on low speed just until combined (do not over mix). Scrape about half of the batter into the baking pan. Sprinkle the apple spice filling over the top and then scrape on the rest of the cake batter.

  The cake batter will be thick. Use a silicone spatula to spread out the batter in the pan.

Streusel Topping

• In a medium bowl (you can use the same bowl that you mixed the flour in) use a fork to combine the brown sugar, apple pie spice, and salt. Add the melted butter and mix until combined. Then mix in the flour. Top the cake batter with your streusel topping (use your fingers because the topping will be slightly wet).
• Bake for 25-30 minutes, or just until the cake is set. Use a toothpick to check the center of the cake. If it comes out clean, the cake is done. Cool on the counter for 10 minutes, then move the baking pan over to a wire rack to finish cooling.

Apple Cider Glaze

• In a small bowl, whisk together the powdered sugar and 1 tablespoon of apple cider. Once the cake has cooled for 30 minutes, drizzle the glaze over the top or use a sandwhich bag with a hole cut in one of the corners.
• Keep any leftover cake slices in an airtight container in the refrigerator for up to 5 days. Feel free to reheat a slice of cake in the microwave for about 25 seconds.
