Turn your oven to 315 degrees and let it preheat.

Beat the room temperature butter in a large bowl for about 2 minutes until it's light and fluffy. Scrape down the sides of the bowl with a spatula if needed.

Add the sugar and cream together with the butter for about 30 seconds. Then add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Add the cake flour and mix just until combined. Be careful not to overmix - stop as soon as you don't see any more dry flour.
05 -
Add the heavy cream and gently fold it into the batter with a spatula. This keeps you from overmixing and makes the cake tender.

Scoop out 1 cup of the batter into a separate bowl. Add the cocoa powder and butterfly pea powder to this portion and mix until the color is even and well combined.
07 -
Spray your bundt pan really well with baking spray. Pour in about half of the plain batter. Use an ice cream scoop to drop scoops of the blue batter strategically over the plain layer. Add the rest of the plain batter on top. Take a knife and swirl it through the layers to create a marbled effect.

Bake for 1 hour and 15 minutes, or until a toothpick inserted in the center comes out clean.

Let the cake cool in the pan for 15 to 20 minutes before turning it out onto a serving plate. If making the glaze, whisk together the confectioner's sugar, vanilla, almond extract, and milk until smooth. Pour it over the cooled cake and enjoy.
