Preheat oven to 390 degrees and prepare your Ramekins ceramic bowls by greasing generously and placing a tablespoon of cocoa in the first Ramekins bowl, and moving the ceramic bowl in a circular motion to make sure the sides and bottom are covered well. Once the first bowl is covered, dump the remaining cocoa powder into the next greased Ramekin bowl and continue until all cookware is coated.
If you’re using a chocolate bar, break it up into little pieces and let the pieces fall into a medium-sized pan and add the butter.
Over low heat, slowly melt the chocolate and butter together. Continuously stir until everything is melted.
In a large bowl whisk together the two eggs, two egg yolks ONLY and sugar until the sugar is dissolved and is well mixed.
Add flour and melted chocolate and mix thoroughly.
Fill baking cups a little less than halfway full and put a heaping spoonful of peanut butter right in the middle. You want to keep the peanut butter in the middle.
Fill up the baking cups about ¾ of the way full. Make sure you completely cover the peanut butter and get the chocolate batter around the sides. You want to keep the peanut butter in the center so the cake holds it in until you're prepared to eat it.
Place the cakes on a cookie sheet in the baking cups and bake for 15 to 17 minutes. Allow them to cool for a few minutes, but keep in mind the Lava Cakes are typically better when they are warm because the Jif Brand peanut butter is melted.
Flip the baking cup upside down on a plate. The cake should slide out; sprinkle cocoa powder or powder sugar and enjoy. Oh, before I forget, you can even put some ice cream on top too.
Sprinkle powder sugar on top
