Can I use regular whole wheat flour instead of pastry flour?

Yes, but your muffins will be slightly denser. Pastry flour is milled finer and results in a lighter crumb.

How should I store these to keep them moist?

Store them in an airtight container at room temperature for up to three days, or freeze them in a freezer bag for up to two months.

Healthy Whole Wheat Chocolate Chip Muffins

Name: Healthy Whole Wheat Chocolate Chip Muffins
Prep time: 15 min
Cook time: 20 min
Total time: 35 min
Yield: 12 servings
Cuisine: american
Ingredients: 2 cups whole wheat pastry flour; 1 tsp baking powder; 0.5 tsp baking soda; 0.25 tsp salt; 0.5 cup plain Greek yogurt; 0.5 cup honey; 2 large eggs; 0.25 cup melted butter; 1 tsp vanilla extract; 0.75 cup mini semi-sweet chocolate chips

I remember the first time I tried baking with whole wheat flour; it resulted in something that tasted more like a dense brick than a breakfast treat. It took quite a few kitchen disasters to realize that the trick isn't just swapping out the flour, but balancing the moisture to keep the texture light and airy. These muffins have become a staple in my house because they actually taste good, not just healthy.

What makes these work is the combination of Greek yogurt and a little bit of melted butter. The yogurt adds a slight tang that cuts through the sweetness of the chocolate, while the honey provides a deeper, more rounded flavor than plain white sugar. I prefer using mini chocolate chips here because they distribute more evenly throughout the batter, meaning you get a little bit of chocolate in every single bite. These keep beautifully on the counter for three days, or you can toss them in the freezer for a grab-and-go morning boost.
