Instructions

In two separate bowls, combine the butter and peanut butter and then the chocolate chips and butter. Melt both (one at a time) at 30 second intervals until smooth. Make sure to stir after every 30 seconds! Set aside.

Combine eggs, sugar, and vanilla in a mixer bowl. Beat on high for 10 minutes. It should be very light and fluffy, and double in size.

Slowly stir in the flour.

Spoon half of the batter into the peanut butter mixture and then the other half of the batter into the chocolate mixture. Gently fold the batter into both mixtures until thoroughly combined.

Now, spoon half the peanut butter batter into a greased 9 inch cake pan and spread it so it’s level. Add the entire chocolate batter on top of the peanut butter layer, spreading it until it’s level. Dollop the rest of the peanut butter batter onto the chocolate layer. Swirl using a dull knife or something similar.

Bake at 350 for an hour and ten minutes, or until puffy and tests done.
