Instructions
- Preheat oven to 350 degrees F and line muffin pans with paper liners (or grease well).
- In a large bowl, whisk together sour cream, oil, eggs and vanilla. Add in sugar until combined completely.
- Add flours, baking powder, baking soda, and salt and stir until combined. Carefully stir in berries.
- Spoon 1 tablespoon of batter into the bottom of each liner, spreading it out to cover the bottom completely. Top with 1 teaspoon of jam and cover with remaining batter (about one heaping tablespoon per muffin cup), covering the jam with the batter.
- Bake for 23-25 minutes, until light golden brown, toothpick comes out clean and batter around berries appears cooked. Cool to room temperature and serve.
- Muffins can be stored at room temperature for 2-3 days or frozen for 3-4 months.
