Step 8
Preheat the oven to 350 degrees and spray and parchment line three 6-inch round cake pans.
Step 9
In a small mixing bowl combine ⅓ cup of milk and the vegetable oil. Set aside.
Step 10
In the other small mixing bowl gently whisk together the remaining milk (½ cup), eggs, and vanilla extract. Set aside.
Step 11
In the bowl of a stand mixer and with the flat beater attachment, combine the flour, sugar, baking powder, baking soda, and salt and give it a quick whisk together.
Step 12
Add in the butter and peanut butter to the dry ingredients and mix on low until it looks like sand.
Step 13
Slowly pour in the milk and oil mixture and mix on low for 2 minutes.
Step 14
Slowly pour the milk, egg, and extract mixture in and mix on low for another 2 minutes. Scrap the sides of the bowl when necessary.
Step 15
Divide the cake batter into the three prepared cake pans and bake for approximately 25-28 minutes or until a toothpick inserted in the center comes out with a few moist crumbs.
Step 16
Allow the cake layers to cool for 10 minutes and then invert them on a cooling rack to fully cool.
Step 17
In the bowl of a stand mixer with the paddle attachment cream the butter and shortening on high speed until light and fluffy. Approximately 10 minutes.
Step 18
Add the icing sugar, vanilla extract, salt, and liquid smoke and mix on low until combined.
Step 19
In a microwave-safe bowl, melt the chocolate chips in 30-second intervals until fully melted and smooth. Stir between each interval.
Step 20
Add the melted chocolate to the buttercream and mix on low until fully incorporated.
Step 21
Turn the mixer up to high and let mix for 5 minutes until smooth and creamy. Scrape the sides of the bowl when necessary.
Step 22
In a microwave-safe bowl, heat the chocolate chips and milk in 30-second intervals, stirring after each interval, until fully melted and smooth.
Step 23
Depending on the kind of milk, the drip may require a touch more milk to thin or a bit more chocolate chips to thicken. *I always test my ganache drips over the edge of the kitchen sink before applying to a cake to check the consistency.
Step 24
Level each cooled peanut butter cake layer and then with the cake leveler cut each layer into half creating 6 total cake layers.
Step 25
Place one leveled layer of peanut butter on a cake board, plate, and/or cake turntable and top with approximately ¾ cup of smoked chocolate buttercream.
Step 26
Repeat with the remaining layers and apply a thin coat of buttercream all over the cake. Refrigerate for 20 minutes.
Step 27
Cover the cake with another layer of buttercream and smooth the sides with a cake smoother.
Step 28
Decorate the cake as you please. I carefully spooned the warm chocolate ganache drip over the edges of the cake and while it was still warm used my offset spatula and, with the tip, dragged it gently around the drip and cake starting from the top and going down to create the textured marbled chocolate look. I topped the cake with a border of chopped up Reeses Peanut Butter Cups, chocolate squares, peanut butter chips, and chopped peanuts. Enjoy!
