Step-by-Step Instructions
To start off, preheat your oven to 350°F (175°C) and prepare your cake pans by lining the bottoms with parchment paper and greasing the sides. In a mixing bowl, whisk together the flour, baking powder, baking soda, and salt. In another large bowl, blend your softened butter and granulated sugar until it’s light and fluffy—this should take about 3 minutes. Then, add in the eggs one at a time, beating well after each addition. Don’t forget to mix in the buttermilk, key lime juice, and lime zest until everything is well combined. Your kitchen will soon fill with a beautiful, citrusy aroma! (See the next page below to continue steps…)
