How to Make the Perfect Key Lime Cupcakes

Ingredients

• 1 1/2 cups all-purpose flour – provides structure and texture.
• 1 cup granulated sugar – adds sweetness and moisture.
• 1/2 cup unsalted butter, softened – contributes richness and flavor.
• 2 large eggs – binds ingredients and adds moisture.
• 1/2 cup buttermilk – keeps the cupcakes tender and adds tang.
• 1/4 cup fresh key lime juice – delivers the signature tangy flavor.
• 1 tablespoon key lime zest – enhances the lime flavor and aroma.
• 1 teaspoon baking powder – helps the cupcakes rise.
• 1/2 teaspoon baking soda – adds leavening for a light texture.
• 1/4 teaspoon salt – balances sweetness and enhances flavor.

Step-by-Step Instructions

1. Preheat the oven: Set your oven to 350°F (175°C) and line a cupcake pan with liners.
2. Cream the butter and sugar: In a large bowl, beat the softened butter and granulated sugar together until light and fluffy, about 3-4 minutes.
3. Add the eggs: Incorporate the eggs one at a time, mixing well after each addition until fully combined.
4. Mix in wet ingredients: Stir in the buttermilk, fresh key lime juice, and zest until well blended.
5. Combine dry ingredients: In another bowl, whisk together the flour, baking powder, baking soda, and salt.
6. Combine wet and dry mixtures: Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix.
7. Fill the cupcake liners: Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
8. Bake: Place the pan in the oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Allow the cupcakes to cool completely in the pan before transferring them to a wire rack for frosting.

For People with Dietary Restrictions: Sugar Substitutes

• Stevia: A natural sweetener that can replace sugar in a 1:1 ratio.
• Monk fruit: Another natural option, often used in a 1:1 ratio for sugar.
• Allulose: A low-calorie sugar substitute that mimics sugar’s taste and texture.
• Note: Avoid using honey or maple syrup as substitutes, as they can alter the texture and moisture of the cupcakes.

Tools You’ll Need

• Cupcake pan
• Cupcake liners
• Mixing bowls
• Electric mixer or whisk
• Measuring cups and spoons
• Rubber spatula
• Cooling rack
• Toothpick for testing doneness

Top Tips from Well-Known Bakers

• Use Room Temperature Ingredients: Ensure your butter, eggs, and buttermilk are at room temperature for a smoother batter and better rise.
• Don’t Overmix: Mix the batter until just combined to keep your cupcakes light and fluffy. Overmixing can lead to dense cupcakes.
• Test for Doneness: Insert a toothpick into the center of a cupcake; it should come out clean or with a few moist crumbs, not wet batter.
• Cool Completely: Allow cupcakes to cool completely before frosting to prevent the frosting from melting.
• Experiment with Flavors: Add a hint of coconut or vanilla extract to the batter for an extra layer of flavor that complements the lime.

Storing and Reheating Tips

• Room Temperature: Store cupcakes in an airtight container at room temperature for up to 2 days.
• Refrigerator: For longer freshness, keep them in the fridge for up to 5 days in an airtight container.
• Freezer: Freeze unfrosted cupcakes for up to 3 months. Wrap each cupcake tightly in plastic wrap and place in a freezer-safe bag.
• Thawing: To thaw, leave cupcakes at room temperature for about 1-2 hours before frosting.
• Reheating: If you prefer warm cupcakes, microwave for 10-15 seconds, but avoid overheating to maintain texture.
