Preparation

Step 1

Preheat oven to 325F.

Grease three 9 x 1 1/2 inch pans.(I personally used just one 9 x 13 pan). Line your bottoms with parchment. Set aside.

Combine flour, baking powder, baking soda, and salt.

Mix together brown sugar, peanut butter and butter for two minutes. Add egg and egg yolk and mix for another 2 minutes. Scrape down the sides and mix for another minute.
Add half of the flour mixture and mix until incorporated about 20 seconds. Then add the sour cream, mixing again for 20 seconds. Gradually add the remaining flour mixture. Add the hot water in a slow, steady stream and mix on low to combine, about 30 seconds. Add the vanilla and mix for another 10 seconds. Add the peanut butter chips and use a rubber spatula to finish mixing the ingredients until thoroughly combined.
Divide the cake batter into the prepared pans, spreading it evenly. Bake for about 22 minutes. If you have 4 inch diameter tart pans like I used, it takes the same amount of time to bake the cake, if not a few more minutes. Use a knife to see if it is done.


Chocolate Glaze
6 ounces semisweet chocolate
4 TBSP unsalted butter

Break chocolate into small pieces and place in a small stainless steel bowl over a pot of hot(not boiling)water. Melt the 4 TBSP butter in a small saucepan, and skim off the white foam that rises to the top. When chocolate is just melted, stir in the clarified butter(discard the white solids left behind). Set aside until chocolate is 86F.

To Assemble: Place cakes on a wire rack. Place rack on top of a cookie sheet so that the extra chocolate has a place to drip onto.Pour chocolate glaze over cake and using a narrow metal spatula, quickly pared it evenly over the top and sides of the cake. Allow chocolate to set to firm consistency before serving. Garnish with chopped peanut butter cup.
