Pre-heat oven to 350 degrees & line a medium sized muffin pan with 12 paper or silicone muffin cups.

Pour the contents of the ball jar into a medium sized bowl.

The brown sugar will be clumpy. Use a spoon to break the clumps into small bits. The tiny bits will dissolve once the wet ingredients are added.

Combine all wet ingredients into a separate bowl and then slowly add the wet to the dry.

Pour the mixture between the 12 muffin cups and bake for 30-35 minutes. Start checking at 25 minutes.

Check with a knife or toothpick, and when it can cleanly be removed, the muffins are done.

Let cool for 10 minutes.
