One day, I had some special guest but not too much time to bake a cake so I wanted to make some special muffins. Looking through my cooking books I find this Peanut butter swirl muffins and I could not move farther: I had to try them !!!  … and I decided to share them with you because they are really amazing !

I simply love this muffins and I find them different with a nutty flavor  and very moist  … in a simple word: delicious !!!

Ingredients ( 12 muffins )

1/2 cup grape seeds oil or canola oil
2 cups all purpose or whole wheat flour (used 1 cup all purpose and 1 cup whole wheat)
2/3 cup brown sugar
1/3 cup unsweetened cocoa powder
1 tbsp baking powder
1/2 tsp baking soda
1/2 tsp salt
1 cup sour cream or Greek yogurt
2 large eggs
2 tsp vanilla extract

For peanut butter swirl
1/2  cup natural crunchy peanut butter (you can use creamy if you like so)
2 tbsp butter, softened
1 tbsp milk (used low fat)
1/2 cup powdered sugar

Let`s do it

Preheat the oven to 375 F.

Line a 12 muffin cups tin with paper liners.

Sift the flour, cocoa, baking powder, baking soda, and salt, together into a large bowl.

In a separate bowl, whisk eggs with oil and sugar until creamy. Add sour cream and vanilla . Gradually stir the flour mixture into the egg mixture, mixing just until combined.

Divide the batter evenly among the prepared pans.

In a small  bowl, beat the butter and peanut butter together until smooth. Add the milk and powdered sugar and beat until smooth. Drop a spoonful of peanut butter mixture on top of each muffin and swirl it in with a paring knife.

Bake for about 20 minutes, or until a toothpick comes out clean. Cool for 5 minutes in the pan before removing each muffin to a wire rack to cool completely. (If you resist not to try one right away :)).
