A no-bake icebox cake with layers of graham crackers, creamy filling, and fresh strawberries and blueberries. Perfect for summer gatherings and requires only 20 minutes of prep.
Make the cake the day before for best texture. Pat berries dry to prevent sogginess. Chill the mixing bowl and whisk attachment for 15 minutes before whipping cream for best results. Use a sharp knife run under hot water for clean slices.
