Bursting Blueberry Crumb Cake

I’ve finished my fair proportion of blueberry desserts however I’ve all the time wished to do a cake with an outrageous quantity of blueberries in it. As in, BURSTING with blueberries. Not simply studded. I dreamed of a blueberry crumble, besides in cake kind. (Sure, these are the ideas that occupy my thoughts at night time).

The query actually was simply how a lot blueberries I might bake right into a cake with out weighing down the sponge a lot it grew to become dense.

I peaked out at 500g (1lb). That’s nearly double the standard quantity utilized in most Blueberry Crumb Truffles.

And with additional blueberries comes additional streusel, that crumbly crunchy caramel high. I suppose generally goals can come true!!

Substances in Bursting Blueberry Crumb Cake

Right here’s what it’s essential to make this.

The blueberries are tossed in a bit flour and sugar so it kinds a jam-like layer that largely suspends on the floor of the cake. The lemon is used to supply wetness to make a number of the flour stick with the blueberries.

You can find that not all of the flour sticks to the blueberries. You’ll want to scatter all of it throughout the blueberry layer. We’d like the total 3 tablespoons of flour to make sure the blueberries don’t sink. Preliminary variations of the cake solely used 1 tablespoon and the blueberries dispersed a bit an excessive amount of for my liking.

Frozen blueberries will work too! Use frozen as a result of they bleed rather a lot when thawed.

The Crumb Topping

That is known as a streusel in baking. It’s a mix made with flour, sugar and butter mixed to make a lumpy combination that’s used so as to add a terrific crunchy topping on the floor of truffles, muffins, bars and many others.

No uncommon gamers right here. The one one price noting is sugar. I desire utilizing caster sugar (superfine sugar) as a result of the grains are finer so I may be assured that I received’t find yourself with sugar grains within the streusel. Nevertheless, when you don’t have it, simply substitute with common sugar.

Lemon Cake

The Lemon Cake is customized from the batter I take advantage of for my traditional blueberry yogurt cake. Nevertheless, the batter is a bit sturdier constructed to face up to the mixed 700g / 1.4lb of blueberries and streusel that we pile on high and nonetheless come out pretty and springy on the finish.

PS I do know that 700g/1.4 lb seems like an insane quantity of blueberries and streusel, however we do shed weight in liquid evaporation because it bakes.

  • Bitter cream – This helps make the sponge pretty and moist as a result of it provides wetness into the batter nevertheless it’s thicker than milk. So we will use much less flour for a similar quantity of batter.

Yup, been there, finished that!).

  • Milk – Full fats is greatest although low fats will work superb too. As with the bitter cream, guarantee it’s not fridge chilly. Take it out half-hour prior, or microwave for 10 seconds.

  • Lemon zest – Zest the lemon earlier than you squeeze out juice to coat the blueberries! It’s unimaginable to correctly zest a lemon as soon as it’s been squeeze of juice. We solely use the zest as a result of it provides pretty lemon flavour. The juice, however, primarily simply provides sourness.

  • Vanilla extract – Higher flavour than imitation vanilla essence. I personally don’t use vanilla bean or vanilla bean paste in truffles as a result of I believe it’s wasted. Reserve it for issues like Crème Brûlée and Flan Pâtissier!

  • Salt – Only a contact, to convey out the opposite flavours within the cake. Normal baking follow today.

In the event you begin within the center, the load of the blueberries pushes the batter out and up the partitions of the pan. However, don’t get too hung up on this step!

    Notice on oven temperature: it’s a bit greater than the same old temperature for baking truffles as a result of the blueberries and streusel add a thick safety layer so we’d like an additional blast of warmth to cook dinner the cake via. On the typical 180°C/350°F (160°C fan), the cake was taking 75 – 80 minutes and the sponge rose a smidge much less.

  2. Cool for 10 minutes within the pan to present it an opportunity to stabilise. Then unclip the edges and use a spatula to slip the cake onto a cooling rack. Cool for an extra 10 minutes earlier than slicing to serve heat (so the ice cream melts!), or totally cool and serve at room temperature.

Heat vs room temperature serving

If you wish to be a standard, this cake may be served at room temperature, with optionally available ice cream or whipped cream on the aspect. That’s the traditional method Crumb Truffles are served. It’s scrumptious and the way in which this cake was initially supposed to be.

However, for the final word Blueberry Crumb Cake expertise, serve it heat with a scoop of melty vanilla ice cream on high. It’s simply such a comforting mixture – the nice and cozy blueberries that burst in your mouth mingling with the cool creamy ice cream, the crunchy bits of caramel-y streusel topping and the delicate cake (which will get softer when heat!) with the trace of recent lemon flavour.

I’m firmly planted on the warm-serving aspect. Attempt it as soon as, and I believe you can be too! – Nagi x
