It’s time to warm things up! Preheat your oven to 375°F (190°C). A hot oven awaits your muffins, ready to turn that fluffy batter into golden brown delights.

Grab your muffin tin and line it with paper liners. This helps in easy removal and adds a chic touch. If you want to get adventurous, lightly spray the liners with non-stick spray. Nobody wants to wrestle a muffin from its liner.

In a bowl, whisk together the flour, baking powder, salt, and cinnamon. Set this aside. Mixing together the dry ingredients before adding liquid helps evenly distribute the leavening agents. A must for fluffy muffins!

In a large mixing bowl, cream together the softened butter and granulated sugar. You want this mixture to be light and fluffy, so don't rush through. A couple of minutes with a hand mixer will do the trick.

Now, drop in the eggs and vanilla extract. Beat this until well incorporated. The eggs will help bind everything, while the vanilla adds that rich flavor we all adore.

Gradually add the dry mixture to the creamed butter and sugar, alternating with the milk. Start with your dry mixture, add some milk, and keep alternating until all ingredients have combined. Be gentle here; overmixing can deflate those muffins.

With every blueberry, you're adding a burst of juicy goodness. Fold them gently into the batter to avoid breaking them apart. Remember, it’s about the joy of those surprises in every bite!

Using a spoon or an ice cream scoop, fill each muffin liner about 2/3 full. This gives them room to rise without spilling over.

Sprinkle a bit of sugar on top of each muffin before baking. This caramelizes beautifully, turning your muffins into a sweet treat that makes for great aesthetics.

Place your muffin tin in the preheated oven. Bake for about 20 to 25 minutes, or until a toothpick inserted in the center comes out clean. The aroma wafting in your kitchen will be irresistible!

Once baked, remove the muffins from the oven and let them cool in the pan for a few minutes. Then, transfer them to a wire rack. Patience is key—they’ll be hot!
