Key lime is one of my favorite flavors. I adore key lime pie. I could eat it every single day. The only thing standing in my way is the fact that key limes are hard to find in New Jersey.
Oh, wow, were they delicious, even without the blackberry filling. I was too lazy for that part.
This recipe made 35 cupcakes. I think I ate about 10 of them before I had managed to see enough people to give them away! I could’ve easily ate them all.
Key Lime Cupcakes with Lemon-Blackberry Buttercream
1 Cup Butter, Softened
2 Cups Sugar
2 tsp Vanilla Extract
4 Tbsp Key Lime Juice
Zest of Two Limes
3 ½ Cups Flour
1 tsp Baking Soda
½ tsp Baking Powder
½ tsp Salt
2 Cups Sour Cream
4-5 Drops Green Food Coloring, Optional
2 Sticks Butter, Softened
1 Tsp Lemon Extract
1/3 Cup Seedless Blackberry Jam
Pinch of Salt
6 Cups Powdered Sugar
2-3 Tbsp Milk
Preheat oven to 350F.
Combine flour, baking soda, baking powder, and salt.
In separate bowl, cream the butter and sugar. Beat in the eggs, followed by the vanilla, lime juice, and zest. Mix well.
Slowly add the flour mixture, alternating with the sour cream. Mix in the food coloring if you’re using it.
Fill cups 2/3 full and bake for 20-25 minutes.
Let cool completely before decorating.
When ready for frosting, beat butter and lemon extract together until creamy. Then, mix in blackberry jam and salt.
Add the powdered sugar and beat until combined. Add the milk 1 tablespoon at a time until you reach the desired consistency. I used three tablespoons. You may need more or less.
Ice the cupcakes and enjoy!
I added the food coloring to the batter because I wanted them to be pretty. My icing didn’t come out as bright as Baked Perfection’s did, but it was still delicious. You could always add some red coloring to that if you wanted.
I should also say that I used 1 ½ cups whole wheat flour and 2 cups all purpose flour, and they were still amazingly moist and delicious. No one had any idea, nor did they believe me when I told them.
I won’t disclose the calorie count of these bad boys. Trust me. You don’t want to know.
