In a medium bowl, sift together the all-purpose flour, baking powder, baking soda, and salt until well combined.

Using a stand mixer or hand mixer on medium speed, beat the softened butter and granulated sugar until pale and fluffy, about 3 to 4 minutes.

Add eggs one at a time, mixing well after each addition. Scrape down the sides and bottom of the bowl to ensure even mixing.
05 -
Add half of the dry ingredients to the batter and mix until just combined. Add strawberry jam and mix until incorporated. Add the remaining dry ingredients and mix just until combined.

Scrape down the bowl, then add sour cream, vanilla extract, and red food coloring if using. Mix until no streaks of flour remain, avoiding overmixing.

Evenly divide batter between prepared pans and smooth the tops. Bake for 35 to 45 minutes or until a toothpick inserted in the center comes out clean. Remove pans to a cooling rack and cool for 10 minutes.

Beat cream cheese and softened butter on medium speed until pale and fluffy, about 2 minutes.

On low speed, blend in powdered sugar, strawberry powder, and salt. Increase speed to medium and beat until creamy. Add milk a teaspoon at a time if the frosting is too thick, mixing until spreadable consistency is achieved.

If cakes are domed, level them by trimming the tops with a serrated knife to ensure flat layers.
13 -
Place one cake layer on a serving plate. Spread just under one-third of the frosting evenly to the edges. Place the second layer on top and repeat with another third of the frosting. Use remaining frosting to cover the sides.

Garnish the cake with sliced fresh strawberries. Serve or refrigerate as needed.
