Oat Bundt Cake

Although the Bundt cake (Kuglóf) is the pride of the Austro-Hungarian Monarchy, this version breaks with the traditional yeasted dough school. Here, oatmeal is not just a 'healthy' additive but a structure-modifying element: during baking, it absorbs moisture, so the dough stays juicy for days, unlike sponges which dry out quickly.

Instructions

1

Preheat the oven to 180 °C (conventional oven). Grease the bundt tin thoroughly with butter, then dust with flour, tapping out the excess.

Tip: Preparing the tin creates a physical barrier between the dough and the metal. If you skip this, the sugar content of the dough may caramelise and stick to the tin [non-sticking].
2

Prepare the dry ingredients: in a bowl, mix the oats, the sifted flour, the baking powder, and the salt.

Tip: Sifting the flour and mixing the dry substances ensures that the baking powder can raise the dough evenly everywhere [homogenisation].
3

Beat the soft butter and sugar with a robot mixer until pale (approx. 4-5 mins), until the volume increases and it has a foamy consistency.

Tip: This step introduces the most air into the dough. The sugar crystals cut tiny holes into the butter, which grow during baking [physical leavening/aeration].
4

Add the eggs one by one: always wait until the buttery cream has fully absorbed the previous one before cracking in the next.

Tip: If you add the eggs all at once, the fat and water may separate, making the cream 'curdled'. Adding them one by one helps create a stable cream [stabilising emulsion].
5

Turn the machine down to a low setting. Alternately, in 2-3 batches, add the flour mixture and the milk, mixing only just until uniform. Finally, fold in the vanilla and lemon zest.

Tip: Here it is forbidden to mix for long! If you overwork it, the proteins in the flour will make the dough 'rubbery', and the cake will be tough [minimising gluten development].
6

Pour the batter into the tin, smooth the top, and bake for 40-45 minutes. Perform a skewer test at 40 minutes: if the skewer inserted into the centre comes out clean, it is done.

Tip: During baking, the water content of the dough turns into steam; this and the gases from the baking powder raise the cake [volume increase].
7

Take it out of the oven and leave it to rest in the tin for exactly 10 minutes before turning it out onto a rack.

Tip: The hot dough structure is still too weak. During the 10-minute rest, the fats and proteins re-solidify enough for the cake to hold its shape [structural stabilisation].

Recipe FAQ

Why did the Bundt cake collapse?
You probably opened the oven door too early, and the structure forming the frame of the dough hadn't solidified yet, and the sudden temperature drop 'shocked' the dough.
Can I use fine oats?
Yes, in fact, the texture of the dough will be even more uniform with them, as they soften faster.
