Raspberry Chocolate Chip Muffins

Source: Sally's Baking Addiction

Ingredients:
3 cups (375 grams) all-purpose flour (very careful not to overmeasure)
4 teaspoons baking powder
1/2 teaspoon salt
1 teaspoon ground cinnamon
2 large eggs, at room temperature
¾ cup (150 grams) granulated sugar
¼ cup (50 grams) light brown sugar
1 cup (240 ml) milk, at room temperature (she prefers buttermilk, so I used my handy-dandy buttermilk substitution with 1 Tablespoon lemon jucie + milk to 1 cup and let it sit for 5 minutes)
½ cup (120 ml) canola/vegetable oil (or melted coconut oil)
1 teaspoon vanilla extract
2/3 cup (120 grams) dark chocolate chips, (or semi-sweet)
1 and ¼ cup (215 grams) fresh raspberries (I used frozen with great results)
coarse sugar (optional)

Directions:
Preheat oven to 425F degrees. Spray muffin pan with non-stick spray. Set aside.

In a large bowl, gently toss together flour, baking powder, salt, and cinnamon. Mix until all dry ingredients are combined - a 20 second toss to disburse everything together. Set aside.

In a medium bowl, whisk together eggs, granulated sugar, and brown sugar until combined. Mix in milk, oil, and vanilla extract. Mixture will be pale and yellow. Fold wet ingredients into dry ingredients and mix everything together by hand. Avoid over-mixing, which will produce tough, dry muffins. Gently mix until all the flour is off the bottom of the bowl and no big pockets of flour remain. The batter will be extremely thick and somewhat lumpy. Fold in the chocolate chips, then very gently to avoid them from leaking their color, fold in the raspberries.

Spoon batter into prepared muffin tins, filling all the way to the top. Sprinkle with coarse sugar if desired (I didn't have any so I left it off, and the muffins were great). Bake at 425F degrees for 5 minutes. Keeping the muffins in the oven, reduce oven temperature to 375F and continue to bake for 13-14 minutes until tops are lightly golden. A toothpick inserted in the center should come out clean. Allow to cool for 10 minutes. Muffins taste best fresh the same day. Store muffins at room temperature in an airtight container for up to 5 days.

Notes:
I had a goal last year to make a new muffin recipe each month.  I'm proud to say I was successful in that goal!  What a delicious resolution, let me tell you!  Well, for December I decided to make these little beauties since I had some frozen raspberries in my freezer.  Oh my!  So delicious!
