This dessert combines the buttery richness of classic pound cake with dramatic blue velvet swirls, created with cocoa and butterfly pea powder. Smooth heavy cream adds incredible moisture, while pure vanilla lends warmth and depth to each bite. The marbling technique, where a blue-tinted cocoa batter is layered and gently swirled, ensures stunning presentation. A creamy glaze or store-bought frosting adds a sweet finishing touch. Perfectly balanced between beauty and flavor, this cake is ideal for gatherings or special occasions, offering a memorable combination of color and taste.

Blue Velvet Swirl Vanilla Pound Cake is the kind of dessert you bring out for the showstopper moment at gatherings. It looks dramatic with its vibrant swirls and tastes even better than it looks. The buttery vanilla-rich batter bakes up into a dense yet tender crumb, and the butterfly pea powder creates that deep blue marbling. Every time I serve this, someone always asks for the recipe and I love watching my friends’ faces light up with curiosity at the first blue slice.

Ingredients
cake flour: three cups gives the pound cake structure while keeping the crumb ultra tender you want a superfine flour for the lightest texture
eggs: five at room temperature contribute to richness and ensure the cake rises fully they should never be cold for the best volume
granulated sugar: two and one half cups sweetens the cake and helps form a crisp exterior crust choose organic or extra fine for a smoother batter
salted butter: three sticks at room temperature give this pound cake that signature flavor and melt in your mouth crumb use a high quality European butter if possible
vanilla extract: two teaspoons bring out all the flavors and give depth always use pure extract not imitation
heavy cream: one cup at room temperature makes the pound cake extra moist and helps develop a lush texture look for a cream with at least thirty six percent fat
cocoa powder unsweetened: one teaspoon just a hint to deepen the blue swirl with warmth pick a dutch process for best color and richness
butterfly pea powder: two teaspoons for that distinctive blue color plus subtle earthiness choose a high quality powder with deep blue color avoid brands with dull gray hue
cream cheese frosting: I love the tang here but you can do classic vanilla glaze see tip for homemade glaze below
vanilla glaze: confectioner’s sugar whole milk vanilla and almond extracts this glaze pours over the cooled cake for a simple finish
Step-by-Step Instructions
Cream the Butter:
Cream the room temperature butter for two minutes in a stand mixer until it is light and fluffy. This aerates the batter and makes the pound cake rise. Be sure to scrape down the sides of the mixing bowl with a spatula to ensure even mixing.
Add Sugar and Eggs:
With the mixer on medium speed continue creaming the butter and slowly add the sugar over thirty seconds. Let it beat until the mixture is pale and fluffy. Then add the eggs one at a time mixing well after each addition to fully incorporate and prevent curdling. Pour in the vanilla extract and blend just until combined.
Incorporate the Dry and Wet Ingredients:
On low speed add the cake flour in three additions. Mix only until just combined you do not want to overwork the batter or the cake will be tough. Gently fold in the heavy cream using a spatula. Folding helps keep the batter airy and avoids overmixing. The batter should be thick but spreadable.
Make the Blue Velvet Swirl:
Scoop out one cup of batter into a separate bowl. Add the cocoa powder and butterfly pea powder mixing until the color is uniform and vivid blue. This will be your swirl.
Layer and Swirl the Batter:
Grease a bundt pan thoroughly with baking spray so every detail releases cleanly. Pour in half of the main batter and smooth the top. Use an ice cream scoop or spoon to create pockets of blue batter across the surface then cover with the remaining vanilla batter. Use a knife to gently swirl once or twice through the batter not too much or you will lose the ribbon effect.
Bake and Cool:
Bake in a preheated oven at three hundred and fifteen degrees Fahrenheit for about one hour and fifteen minutes. The cake should rise and crack on top and a tester inserted in the thickest part will come out clean. Let the cake cool in the pan for fifteen to twenty minutes then turn out onto a wire rack to cool completely before glazing.
Frost or Glaze the Cake:
For full celebration effect use a generous pour of cream cheese frosting or drizzle the simple vanilla glaze over a completely cooled cake. Garnish with sprinkles or edible flowers if you like.

You Must Know
dessert keeps well for up to four days covered at room temperature
can be made ahead and frozen tightly wrapped for up to two months
butterfly pea powder is loaded with natural antioxidants for a pop of color and a superfood boost
Butterfly pea powder is my secret weapon for this cake and always gets everyone talking. I first tried it after spotting a blue latte at a café and was hooked by the color. The kids in my family now call this the magic cake.
Storage Tips
Let your pound cake cool completely before wrapping. I like to wrap it twice in plastic and store it in a lidded cake keeper at room temperature which keeps it from drying out. You can slice and freeze extra cake pieces wrapped in parchment or foil for up to two months. Just thaw at room temperature before serving.
Ingredient Substitutions
If you cannot find butterfly pea powder swap in blue spirulina for a similar effect though the flavor will differ. For a dairy free cake use plant based butter and substitute coconut cream for the heavy cream but expect a more tender crumb. You can use all purpose flour in place of cake flour in a pinch just remove two tablespoons per cup and replace with cornstarch for lighter texture.
Serving Suggestions
Blue velvet pound cake looks even more stunning with a sprinkle of edible dried petals or fresh berries on the cake stand. Serve with extra glaze for guests who like more sweetness or alongside an ice cold glass of milk. It also makes a show stopping brunch option sliced with tea or coffee.
