Step 1

Preheat the oven to 350º F. In a large mixing bowl, beat together the peanut butter, sugar and brown sugar with an electric mixer until combined, 1-2 minutes.

Step 2

Beat in the eggs, buttermilk and vanilla extract, mix briefly. Gradually add the flour, baking powder, and salt, mixing on low to prevent over mixing. Be sure to mix just until combined.

Step 3

Spray a loaf pan (either 9×5 or 8.5×4.5 - it’s important to know what size pan you have) with non-stick cooking spray. Transfer the batter to the pan and spread even with a spatula.

Step 4

Place the pan in the center of the oven and bake for 45 minutes. After 45 minutes check to see if the bread is browning too much. If so, tent the bread with aluminum foil and bake for 10-20 more minutes. **If you didn’t tent at 45 minutes, check again at 55 minutes, then tent, and bake for 10 additional minutes or until a toothpick inserted in the center comes out clean.

Step 5

The total suggested bake time for a 8.5×4.5 inch pan is 55-65 minutes and 9×5 inch pan is 45-60 minutes. Be sure to know what size your pan is.

Step 6

Allow the loaf to cool completely before slicing or removing it from the pan.
