I found a recipe for basic muffins, and adapted from there. I've posted the recipe I used below, however, I didn't think they were sweet enough. Next time I make them, I'll either add a little more sugar, or possibly just more vanilla. They would also be great with a sugar/cinnamon topping of some sort.
The source where I got the recipe also suggested some savory fillings/toppings. I'm definitely going to try some cheesy herb muffins this weekend. Also, I looked around the other recipes on Diana's Desserts - they look amazing! If you're looking for a dessert idea, go check this site out. I made a list of all the things I want to try.
adapted from Basic Muffin Recipe with Variations
1 cup all-purpose flour
3/4 cup white whole wheat flour
1/4 cup granulated sugar
2 Tbsp baking powder (that looked like a lot, but they were fine)
1/2 tsp salt
1/8 tsp cinnamon, optional
3/4 cup milk
1 large egg
1/3 cup unsweetened applesauce
1/2 tsp vanilla
approx 1/3 cup each blueberries and strawberries
Preheat oven to 400 degrees and prepare a muffin tin.
In a medium mixing bowl, combine flours, sugar, baking powder, salt, and cinnamon. To this, add the milk, egg, applesauce, and vanilla. Stir just until combined (don't want to overmix muffins). Gently fold in berries. (I wanted blueberry muffins and strawberry muffins separately, so I just split my batter in half, and did blueberries in one and strawberries in the other.) Transfer to prepared muffin tins.
Bake at 400 degrees for 20-25 minutes, or until toothpick inserted in center comes out clean. Let cool, and enjoy!
