Add contents of bowl #1 to bowl #2. Do NOT use a mixer. Gently fold until just combined.
Place cake pans on a baking sheet and bake for 30 minutes. Take the cakes out and let them rest for 10 minutes.
Before returning the cakes to the oven, gently tap the bottom of the baking sheet to remove remaining bubbles and rotate the pan so the opposite side of the cake is towards the front. Bake for an additional 30 min.
Let the cakes cool completely. Frost with Buttercream frosting. Sprinkle with additional pecans for decoration.
Notes
This cake was made with a natural gas oven, other types of ovens might differ on time.
