DIRECTIONS
For the Cake
- Preheat the oven to 350° 
- Spray three 8 inch cake pans with nonstick spray and line with parchment paper. 
- Heat milk in microwave safe container for about 15 seconds. 
- Pour the milk in a cup or bowl and add the instant coffee mix. (This is one packet from a box of instant coffee.) Stir and set aside. 
- Combine flour, baking soda, baking powder, and pumpkin pie spice in a bowl and whisk to combine. 
- In large bowl, beat butter on medium speed until smooth and creamy. 
- Add granulated and light brown sugar and mix until fluffy. 
- Add the can of pumpkin puree and mix well. Then add the eggs and vanilla extract, mixing until incorporated. 
- Add half of the flour mixture and half of the milk mixture. (The coffee should be completely dissolved at this point.) Mix until just combined. 
- Repeat with the second half of the flour and milk. Mix for one more minute. 
- Divide the cake batter evenly between the three prepared pans and bake for 15–17 minutes, or until a toothpick inserted into the center of each cake comes out clean. 
- Let the cakes cool in the pans for 10 minutes. 
- Transfer to a wire rack to cool completely. 
For the Spiced Buttercream
- In the bowl of a stand mixer, beat butter on medium speed until smooth and creamy. 
- Add pumpkin pie spice, vanilla extract, and milk. 
- Add half of the powdered sugar. Mix on low speed until just combined, then medium speed until fully combined. 
- Repeat with the second half of the powdered sugar. 
- Beat on medium speed for another minute. Spread frosting between the cooled cake layers. 
For the Kahlua Caramel Sauce
- In a saucepan over medium high heat, cook sugar until it starts to melt on the bottom. 
- Stir pretty continuously so it doesn't burn. 
- While stirring, the sugar will stick together and form hard clumps/shards. 
- At this point, you don't have to stir AS much because you want the sugar to get hot enough to melt and turn a golden brown color. So stir the sugar, give it a moment, and then stir again. 
- Stir again, repeating this process until all the clumps are melted and the sugar has turned golden brown. Reduce heat to medium. 
- Stirring continuously with one hand, add the butter with the other. 
- Once all butter has completely melted, still continuously stirring, slowly pour in the Kahlua. 
- After you've added the Kahlua, let the mixture simmer for 1 minute. It will bubble up and double in height. 
- Remove pot from heat and stir in salt. 
- Let the caramel sauce cool before using. Store in a jar or sealed container in your fridge. Warm up caramel in microwave in 30 second increments before future use. 
- Once it's mostly cool (it can still be a tad warm), drizzle over cake. 
- Top with whipped cream. 
For the Whipped Cream
- Combine all ingredients in a bowl (or the bowl of a stand mixer) and mix on medium-high speed until stiff peaks form. 
- Transfer whipped cream to a piping bag and pipe all over the top of the cake.
