Makes Two Tall 6-inch Layers
Ingredients
2 cups all-purpose flour
1½ tsp baking powder
½ tsp baking soda
½ tsp fine sea salt
¾ cup (1½ sticks) salted butter, softened
1 cup maple sugar
3 large eggs
¼ cup fresh lemon juice
1 tsp vanilla extract
¾ cup milk
2 tbsp sour cream or plain yogurt
Instructions
Preheat oven to 350°F. Grease and line two deep 6-inch pans with parchment .
Whisk flour, baking powder, baking soda, and salt in a bowl.
In another bowl, beat butter and maple sugar until light and fluffy (2–3 minutes). Add eggs one at a time, beating well after each. Mix in lemon juice and vanilla.
Add half the dry ingredients, then milk + sour cream, then remaining dry ingredients. Mix just until smooth then stop. You don’t want to over mix.
Divide evenly between pans and bake 38–45 minutes, until tops spring back and a toothpick comes out clean.
Cool completely. Chill layers 20–30 minutes before assembling for easiest stacking.
