Look at the yummy muffin! :) You can bake them with any berries you want: blubbery, cranberry, raisins... they are all will be good!
For the recipe, we will need:
2 cups (1 up is 240 ml) of all purpose flour
2/3 cup of sugar
2 tea spoon of backing powder
1 cup of fat reduced sour cream (I used fat free Greek style yogurt)
1/4 cup of canola oil (or any other oil with no scent)
1 tea spoon of vanilla extract
2 cups of butter milk or kefir
Resins, walnuts, cranberries... 1/2 cup of each. You can use or just resins, or nuts, etc. I like to mix all of them. Also, 1 cup of blueberries will be fine. Well... any your favorite berries :) Around 1 - 1 1/2 cups...
Preheat oven to 390 F (200 C)
Mix in a bowl flour, sugar, and backing powder
In separate bowl, mix sour cream, oil, egg,and vanilla. Mix them until smooth.
Add dry ingredients to the batter and mix well. The mixture will be dry. So mix in butter milk or kefir little by little. The finish mixture should be thick but liquid. If it's too thick, just add more butter milk. Add berries and nuts.
Spray or brush muffins caps with oil and place them in muffin pan.
Spoon the batter in the caps. Fill around 2/3 of a cap.
Put the muffin pan in the oven and bake the muffins until golden brown. Try them with wooden tooth pic. Depends on oven, it may take 20-30 minutes.
Enjoy your muffins! :)
