Let’s walk through the steps to your sweet success.

You want your oven to be at the right temperature for an even bake. Preheat it to 350°F (175°C). It’s always a good idea to do this first, so the oven is ready when you are.

Line a muffin pan with muffin liners or grease it lightly. This will prevent sticking and make clean-up a breeze. Additionally, it helps keep those muffins nice and moist.

In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. This step ensures that all the leavening agents are evenly distributed throughout the flour, giving your muffins a nice rise.

In a large mixing bowl, beat the butter with the granulated sugar until it’s light and fluffy. This typically takes about 3-4 minutes. Incorporating air into the mixture at this stage is vital for that fluffy texture.

Break the eggs and add them, along with the sour cream and vanilla extract, to the butter-sugar mixture. Mix until everything combines smoothly.

Now it’s time to slowly add the dry ingredients to the wet ones. Mix just until incorporated. Overmixing can create dense muffins, and that’s not what we want!

Gently fold in the Dunkin’ Donuts Extra Extra Creamer. This will enrich the muffins and add that signature Dunkin’ taste.

In a separate bowl, combine the flour, sugar, brown sugar, and cinnamon. Add cold, cubed butter and use a pastry cutter or your fingers to mix it until it resembles coarse crumbs.

Scoop the muffin batter into your prepared tin, filling each cup about two-thirds full. Sprinkle a generous amount of crumb topping over each muffin.

Place the muffin tin in the oven and bake for about 18-20 minutes, or until a toothpick inserted comes out clean. The muffins should be golden brown on top.

While the muffins bake, whisk together the powdered sugar and Dunkin’ Donuts Vanilla Creamer to create a simple glaze. Add the fresh nutmeg if you’re feeling fancy.

Let the muffins cool in the pan for about 5 minutes before transferring them to a wire rack. Drizzle the glaze over the warm muffins. This adds extra sweetness and a lovely finish.
