Essentials for Cupcakes

• 1⅓ cups cake flour – For a soft and airy texture
• 1 tsp baking powder – Helps the cupcakes rise
• ½ tsp salt – Enhances the overall flavor
• ⅓ cup whole milk – Adds moisture and richness

• 2 tbsp sour cream – Adds tang and extra moisture
• 1 tsp vanilla extract – Brings out sweet flavors
• ½ cup unsalted butter, room temperature – Provides richness
• 1 cup granulated sugar – For sweetness and structure

Peach Puree Filling

• 3 cups peaches, peeled and sliced – Fresh, ripe peaches for the filling and frosting
• ¼ cup sugar – To sweeten the puree
• 1 tsp lemon zest – Adds brightness
• 2 tsp lemon juice – Balances the sweetness
• 2 tsp cornstarch – Thickens the peach filling
• ¼ tsp cardamom – Warm spice that complements the peach
• ¼ tsp cinnamon – Adds depth and warmth

Peach Buttercream Frosting
