While I certainly don't make cakes often, I jump at the chance when I can.

There's just something about being covered in buttercream and delivering someone a delicious confection. While most of my treats err on the healthier side, a birthday treat is just that- a treat, so full dairy, sugar, and gluten are welcome. (Except for my birthday, that would result in some serious inflammation that's just not worth it.)

I'll keep this post short- since you'll get enough sweet from this cake. If looking for a delicious birthday treat for a chocolate, coffee, beer-lover, try this combo out.

It's worth the effort.

Dulce De Leche

  • 1 can of sweetened condensed milk, label removed


  1. Fill a large pot with water and place the can in- making sure the water covers the can. Bring to a boil then lower heat to a simmer.
  2. Simmer for 2 hours and 30 minutes, then flip the can and simmer for another 30 minutes.

  • 1 teaspoon vanilla extract 
  • 1-3 tablespoons milk


  1. Cream together the butter and powdered sugar. Then add in the vanilla and espresso.
  2. Add milk if needed to get a smoother consistency. 

Cake Assembly

  1. Once the cake has cooled, cut off any domes to ensure an even surface.
  2. Then add a layer of frosting, topped by a drizzle of dulce de leche.
  3. Repeat with remaining layers.
  4. With remaining frosting cover the top and outside of the cake.
  5. Use the remaining dulce de leche to create a glaze on top of the cake and drip over the sides.
  6. Chill to allow layers to set.
  7. Enjoy!
