Swap: Try coconut sugar for a caramel note. - 1/2 cup (115g) unsalted butter, softened
Swap: Use olive oil for a Mediterranean twist, or vegan butter for dairy-free. - 2 large eggs, room temperature
Swap: 1/2 cup unsweetened applesauce or flaxseed “eggs” (2 tbsp flaxseed + 6 tbsp water) for vegan. - 2/3 cup (160ml) whole milk
Swap: Almond, oat, or soy milk for dairy-free. - 1 1/2 tsp vanilla extract

Step-by-Step Instructions
Step 1: Prep Your Pan and Oven
Preheat your oven to 350°F (175°C). Grease an 8- or 9-inch round cake pan and line the bottom with parchment paper for easy release a simple step that boosts your cake’s photo-worthy outcome.
Step 2: Cream Butter & Sugar
With a stand mixer (or by hand), cream the softened butter with sugar for 2–3 minutes until it’s pale, fluffy, and doubles in volume. This incorporates air for a lighter crumb a key trick backed by professional bakers.
Step 3: Add Eggs
Beat in the eggs one at a time, mixing well after each. Scrape down the bowl to ensure even mixing uneven batter is a top cause of dense cakes.
Step 4: Combine Dry Ingredients
In another bowl, whisk together the flour, baking powder, and sea salt. Sift for best results; sifting prevents clumps and ensures a pillowy crumb.
Step 5: Add Alternately with Milk
With your mixer running on low, add half the dry ingredients to the wet, then pour in half the milk, followed by the rest of the dry, then the milk. Finish with vanilla extract. Don’t overmix stop once combined to prevent toughness.
Step 6: Bake
Pour batter evenly into your prepared pan. Tap gently to release air bubbles for a flat, even rise. Bake for 28–32 minutes, or until a toothpick emerges clean from the center. For extra moistness, check at 27 minutes and cover loosely with foil if browning too quickly.
Step 7: Cool & Frost
Let the cake cool in the pan for 10 minutes, then transfer to a rack. Once cool, frost as desired cream cheese, whipped ganache, or a fruity glaze are all perfect.
Pro Tip: For ultra-tender cake, brush with simple syrup before frosting.
