Step 1

In a medium bowl combine the flour, baking powder, and salt. Set aside.

Mix the Dry Ingredients

In  a large bowl with a handheld electric mixer on medium speed combine the butter and sugar for 4-5 minutes, so it's nice and fluffy.

Beat the Butter and Sugar

Step 2

Add in the vanilla extract then eggs one at a time, making sure to scrape the sides of the bowl.

Add the Eggs and Vanilla

Step 3

To the butter mixture add ⅓ of the dry ingredients, mixing until just combined, then ½ of the wet ingredients, then repeat with the remaining ingredients ending with the dry ingredients.

Mix the batters

Step 4

Scoop two cups of cake batter into another medium bowl and add in the cocoa powder, melted chocolate and milk then mix until just combined.

Make the Chocolate Batter

Step 5

I used a large ice cream scoop to add one scoop of vanilla cake batter, then a scoop of chocolate, and alternating until full. You can then use a butter knife to gently swirl the cake, sometimes

Scoop the Batter

Step 6

Let the marble cake cool on a wire rack for 30 minutes then I use a small angled spatula to gently release the cake from the pan then place a wire rack on top of the cake and flip over to invert the cake onto the cooling rack.

Make the Glaze

Step 7

When ready to use I like to pour it into a measuring cup with a pour spout to easily drizzle it on the cake.

Decorate
