Strawberry Lemonade Cupcakes
My strawberry lemonade cupcakes are made easy using a box of cake mix. They have a soft and fluffy lemonade base and a sweet strawberry buttercream frosting on top!
These strawberry lemonade cupcakes are summer in cupcake form. They start with a box of lemon cake mix that I doctor up a bit. Then I top them with the best homemade strawberry frosting and garnish with a cute straw and a lemon wedge.
They take around an hour to make (maybe a little more depending on your speed in the kitchen). You’ll get about 20 soft, flavorful cupcakes that are perfect for sharing!
Kim’s Cupcake Making Tips
- Don’t overmix the batter. Overmixing whips in extra air and overdevelops gluten, causing the cupcakes to get tough, sink in the center, or dome.
- Let the cupcakes cool completely before frosting. If you frost warm cupcakes, that buttercream is going to melt and slide right off.
- About the strawberry purée. Some people report using too much puréemakes the buttercream runny. I’ve never had that issue personally. My recommendation is to start with less and add only enough to get the frosting to the desired consistency.
- Ingredients on the box: Use the ingredients listed on your box of cake. Then add these extra ingredients: vanilla pudding, sour cream, lemonade mix (like Country Time), and vanilla extract. The ingredients listed on the box are usually eggs, water, and oil but the amounts vary by brand.
