Recipe: Blueberry Bublanina | Bubbly Cake

From early springtime all the way into the deep heart of fall, Slovakia’s mountains and hills burst with nature’s bounty. For those who search, a perpetual harvest reveals herself. Here, trees swoon with the weight of delightfully sour cherries, juicy, grapes, apricots, and apples. There, bushes bloom with blueberries, woodsy and sweet.

This land, surely, is magic.

When there is more fruit than can be gathered in an apron, Slovakia makes Bublanina, a.k.a. Bubbly Cake.

Just one secret makes this slightly sweet cake light and fluffy: whipped egg whites. Fruit, sliced, chunked, or left whole, is scattered across the foamy surface and, as the cake puffs up in the oven, it bubbles around the fruit.

Some fruit sinks down. Some fruit does not.

Once out of the oven, the whole thing is covered with a cloud of powdered sugar, until even the air around it tastes sweet.

It’s all kinds of whimsical and the perfect way to ring in the hope of spring (I promise it’s coming – I even witnessed a few daffodil leaves peeking through the hard earth last weekend).

Since Bublanina is an airy cake, it’s important to have all your prep done ahead of time, so it doesn’t deflate.

So … first things first:

Preheat oven to 375F degrees.

Grease an 11×9 pan.

Toss the fruit with a spoonful of flour and set aside.

Now for some mixing bowl fun.


In a small bowl, whisk together the dry ingredients: flour, powdered sugar, baking powder, lemon zest, and salt.

Breathe in that lemon love! Happy Valentine’s Day, friends.


Next, in a large bowl, whisk together wet ingredients (milk, egg yolks, and vegetable oil) until a smooth batter forms.


Whip the egg whites in a clean, dry bowl until glossy, stiff peaks form.


Add the dry ingredients to the wet and stir until a smooth batter forms.

Using a spatula, fold the egg whites into the batter.. do it in thirds, until the mixture is airy and

Pour this voluptuous batter into your baking dish and cover randomly with fruit. Be gentle, so as to not overly deflate the cake. Some fruit will sink immediately and that’s okay. In this photo, I only needed 1 3/4 cups fruit.


Bake for about 30 minutes, or until a toothpick inserted comes out cleanly.


Cool, cut into squares, and cover with a snowfall of powdered sugar. boy.

  1. Looks like a perfect Valentines cake to me!

  2. I want spring, I want to be in those pictures, and I want some of that cake!

      We keep getting teases of spring – a 60 degree day right after a night of snow. Tulsa’s weather is very confusing but always exciting :)

  3. Oh, this cake of cake is my favorite! Packing the whole business full of fruit really makes it. I think I could also manage a slice or two for breakfast… :)

  4. Is Bublanina a more cake-like kissing cousin of the French Clafouti? The French dish does not call for separated eggs, and is most commonly served while warm, but the general assembly is about the same. And both words are fun to say!

    • Sasha Martin says:

      It’s similar, but the texture is very light and spongey. If you don’t whip the whites (which I tried), it’ comes out very dense but not quite as delicate as clafouti… so definitely whip those whites ;)

  5. Kebby Jones says:
