Preheat oven to 350 degrees F. Spray a 9x13" cake pan with nonstick cooking spray.
In a large mixing bowl, add in cake flour, sugar, baking soda, baking powder, salt, cinnamon, ginger, nutmeg, and cloves. Whisk until combined.
In a microwave-safe medium bowl, add in the butter. Microwave for 30 seconds to 1 minute.
Add in the Oregon Chai Tea Latte Concentrate, vegetable oil, sour cream, vanilla extract, and eggs. Whisk until smooth.
Pour the chai latte mixture in with the dry ingredients. Whisk until everything is combined. Try to whisk out most of the lumps.
Pour the batter into the prepared cake pan.
Bake for 40 to 45 minutes or until it's done. Place a toothpick in the center of the cake and if it comes out clean or with moist crumbs it's done.
While the cake is baking, prepare the pudding.
Let the cake cool completely before doing the next step.
Using the round handle of a wooden spoon, begin poking holes into the cake. Do 6 - 7 holes in each row and 8 to 10 rows.
Pudding
In a bowl, add in the lightly beaten yolks, whole milk, and Oregon Chai Tea Latte Concentrate. Whisk to combine. Set aside.
In a medium saucepan, add the sugar, cornstarch, and salt. Whisk until combined. This will help prevent the cornstarch from clumping when liquid is added.
Add about ½ - ¾ cup of the milk/chai latte mixture into the saucepan and whisk until smooth.
Add in the remaining milk/chai latte mixture and whisk.
Place over medium heat and whisk pretty constant to prevent the pudding from sticking/ burning on the bottom of the pan and clumps forming.
Once the pudding comes up to a boil, let it boil for 1 minute while whisking constantly. The pudding should hold the lines from the whisk.
Place a fine mesh strainer on top of a bowl. Pour the pudding into the strainer and tap out the pudding. Avoid pushing the pudding through the strainer because the bits of eggs will push through too.
Place the plastic wrap on the surface of the pudding. Place in the fridge until it cools down.
Add the cooled pudding into a storage bag or a disposable piping bag. Cut the corner or tip out of the bag. Make sure it isn't too big of a hole, you'll want to have control of the pudding coming out.
Fill the holes in the cake with the pudding. Squeeze any remaining pudding on top of the cake and spread out with an offset spatula.
Whipped Cream
In a mixing bowl, add in the heavy cream and cinnamon. Beat on medium with a hand mixer until soft peaks form.
Add in the powdered sugar and continue to beat on medium until the whipped cream becomes stiff.
Add dollops of whipped cream on the top of the pudding layer. Using an offset spatula, begin spreading out the whipped cream until it's evenly distributed and completely to the edges and corners.
Cover and chill in the fridge to let the pudding firm up.
