Start your baking journey by gathering all your ingredients and softening the unsalted butter at room temperature for about 30 minutes. Preheat your oven to 350°F (175°C), allowing it to reach the perfect temperature for baking those fluffy Valentine Themed Cupcakes. Position your cupcake liners in a muffin tin, ready for the delicious batter to come.

In a large mixing bowl, cream the softened butter and granulated sugar together using an electric mixer on medium speed for 3-5 minutes until the mixture is light and fluffy. Beat in the large eggs one at a time, ensuring each is fully incorporated before adding the next. Finish by stirring in the fragrant vanilla extract, combining the wet ingredients beautifully.

In another bowl, whisk together the all-purpose flour, baking powder, and salt until they are well mixed. This will help ensure that your dry ingredients are evenly distributed throughout the batter, avoiding any clumps and contributing to the perfect rise in your Valentine Themed Cupcakes.

Gradually add the dry ingredients to the wet mixture, alternating with the milk for optimal texture. Start and end with the dry ingredients, mixing at low speed just until you achieve a smooth batter. Avoid overmixing to keep your cupcakes light and airy, a crucial step for the irresistible results you’re aiming for.

Fill each cupcake liner about two-thirds full with the batter, using a measuring cup or ice cream scoop for even portions. Pop the muffin tin into the preheated oven and bake for 20-25 minutes. You’ll know they’re done when the tops are golden and springy, and a toothpick inserted into the center comes out clean.

After baking your Valentine Themed Cupcakes, allow them to cool in the muffin tin for 5-10 minutes. Once slightly cooled, gently transfer them to a wire rack to cool completely. This step is essential, as it prevents the frosting from melting and ensures that you have the perfect texture for decoration.
