1-First Step: Prepare your workspace and oven. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line with parchment. Chop 2 cups cranberries into halves or quarters. Toss in 2 tablespoons cake flour to coat evenly. This stops sinking and color bleed. Set aside. Room-temperature ingredients mix better, so let butter and egg whites sit out 30 minutes.

2-Second Step: Mix dry ingredients. In a medium bowl, whisk 3 cups cake flour, 1 tablespoon baking powder, and 1/2 teaspoon salt. Sifting prevents lumps for finer texture. This base ensures your white cake recipe stays light and airy, key for holiday appeal.

3-Third Step: Cream butter and sugar. In a large bowl, beat 1 cup softened butter with 2 cups sugar using a hand mixer on medium speed for 3-4 minutes. Mixture turns pale and fluffy, trapping air for rise. Scrape sides often. Add 4 egg whites one at a time, beating well after each. Beat in 1 teaspoon vanilla until smooth. This creates the batter’s structure.

4-Fourth Step: Combine wet and dry. Add dry mix and 1 cup milk alternately to butter mixture, starting and ending with dry. Mix on low just until combined, about 1 minute per addition. Overmixing toughens the cake. Batter looks thick and smooth now. Gently fold in floured cranberries with a spatula. Streaks of red add festive pops.

5-Fifth Step: Bake the layers. Divide batter evenly between pans, about 3 cups each. Smooth tops. Bake 25-30 minutes until toothpick inserted in center comes out clean or with moist crumbs. Edges pull from pan sides. Rotate pans halfway for even browning. Cool in pans 10 minutes, then turn onto wire racks to cool fully, 1 hour. Layers firm up as they cool.

6-Sixth Step: Make the frosting. Beat 1/2 cup softened butter until creamy. Gradually add 2 cups powdered sugar, 4 ounces melted and cooled white chocolate, and 1 teaspoon vanilla. Whip on medium-high 2-3 minutes for light frosting. Taste and adjust sweetness. If too thick, add 1 tablespoon milk.

7-Seventh Step: Assemble the cake. Place one layer on serving plate. Spread 1 cup frosting on top. Add second layer. Frost top and sides smoothly. Use offset spatula for clean edges. Chill 15 minutes to set.

8-Final Step: Garnish and serve. Top with sugared cranberries: roll fresh ones in sugar. Add rosemary sprigs for pine look. Slice into 10-12 pieces. Serve at room temp with coffee or hot cocoa. Total time: 1.5 hours. Store as noted below. This cranberry cake for Christmas impresses guests every time.
