Let’s bake these delicious Coffee Cupcakes with Condensed Milk Frosting!

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Line two muffin tins with cupcake liners.

Step 2: Combine Dry Ingredients

In a large bowl, whisk together the flour, instant espresso, salt, baking powder, and baking soda.

Step 3: Cream Butter and Sugars

In another large bowl, using a hand mixer (or a stand mixer fitted with the paddle attachment), beat the softened butter, granulated sugar, and brown sugar together until light and fluffy.

Step 4: Add Sour Cream and Eggs

Add the room-temperature sour cream and beat until incorporated. Scrape down the sides of the bowl.

Add the eggs one at a time, beating well after each addition. Then, add the vanilla extract.

Step 5: Alternate Adding Dry Ingredients and Coffee

Add the dry ingredients to the wet ingredients in two additions, alternating with the freshly brewed coffee. Begin and end with the dry ingredients. Beat until just combined after each addition. Be careful not to overmix.

Step 6: Fill Cupcake Liners

Using a large cookie scoop (or a spoon), fill the cupcake liners about ¾ full with batter.

Step 7: Bake

Bake the cupcakes until a toothpick inserted into the center comes out clean, about 20 minutes.

Step 8: Cool

Let the cupcakes cool in the muffin tins for a few minutes before transferring them to a wire rack to cool completely.

Step 9: Make the Frosting

While the cupcakes are cooling, make the frosting. In a large bowl, using a hand mixer (or a stand mixer fitted with the whisk attachment), beat the softened butter until it’s light and fluffy and pale in color, about 3 minutes.

With the mixer running on medium speed, slowly and gradually add the cold sweetened condensed milk.

Add the vanilla extract and salt and beat until the frosting is stiff and holds its shape.

Step 10: Frost and Serve

Transfer the frosting to a piping bag fitted with a tip of your choice (or you can simply spread it onto the cupcakes with a knife or spatula).

Pipe the frosting onto the cooled cupcakes. Serve and enjoy!
