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.

Substances in Bursting Blueberry Crumb Cake

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

The blueberries

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.

Bursting Blueberry Crumb Cake ingredients

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.

Flour – simply plain / all goal flour. It’s greatest to make use of plain flour and add baking powder fairly than self elevating flour. Truffles simply by no means rise as effectively.
Baking powder – That is what makes the cake rise. If yours is previous, it’s greatest to verify it’s nonetheless energetic!
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. Make sure the bitter cream is at room temperature, ie not fridge chilly, else it is not going to incorporate correctly into the batter (eg it might probably make the melted butter solidfy. 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.
Eggs – Use massive eggs that are ~55 – 60g / 2 oz every (they arrive in cartons labelled “massive eggs”) at room temperature. See right here for what this implies, and a fast method to de-chill fridge chilly eggs!
Melted butter – As soon as melted, let it cool for a bit. It could possibly nonetheless be heat, we simply don’t need it to be tremendous sizzling.
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.

Tips on how to make Blueberry Crumb Cake

Streusel first (it’s a fast combine), then toss the blueberries, then make the batter final.

1. Tips on how to make Streusel

How to make Bursting Blueberry Crumb Cake

Combine the dry substances (flour, sugar, cinnamon and salt). Then add the melted butter and vanilla, and blend utilizing a fork simply till all of the flour is moist however the combination remains to be clumpy.
That is what you’re after. Tons and many lumps!

2. zest lemon fiRst, then toss the blueberries

Zest the lemon then hold it for the batter. Do that earlier than juicing the lemon for the blueberries as a result of it’s unimaginable to zest a lemon that’s been squeezed of juice!
Toss the blueberries in lemon juice first to moist the floor. Then toss with the flour and sugar. Then put aside till required.

3. The lemon cake batter

Line a 20cm / 8” springform cake pan with baking / parchment paper. See right here for my simple method of doing it – no pencil required!

It must be a springform pan so the cake may be eliminated with out inverting (which might trigger the crumbly topping to fall off!)
Whisk dry – Whisk the dry ingredient in a bowl (flour, baking powder and salt).
Whisk moist – Then in a bigger bowl, give the sugar, vanilla, zest and eggs whisk for about 15 seconds till the floor is a bit foamy. Add the melted warm-not-hot butter and bitter cream, then whisk till easy.
Add flour in 3 batches – Add one third of the flour then use a rubber spatula to fold it via. As soon as largely integrated, add half the remaining flour, fold via, then the remaining flour and fold via.

Milk final – When you possibly can now not see flour, add the milk and blend till integrated. In the event you see tiny bits within the batter, it is going to be the zest not flour lumps!
Batter thickness – That is what your batter ought to appear to be. Pourable however not tremendous skinny like my Chocolate Cake and never tremendous thick like a muffin batter.

4. ASSEMBLING AND BAKING

Pour the batter into the cake pan and easy the floor.
Prime with blueberries. For probably the most even unfold, begin from the periphery then work your method in. 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! It is a rustic cake, and the blueberry layer is all the time a little bit of a pot-luck state of affairs when it comes to spottiness / jammy patches / how neat the road is (it isn’t, ever!).
Use residual flour – Ensure you tip the residual flour and sugar on the backside of the blueberry bowl over the blueberries. We’d like all of the flour to make sure the blueberries don’t sink (I had issues once I used barely much less flour).
Streusel – Then cowl the highest with the streusel, utilizing your fingers to make good huge lumps throughout the floor. Intention for round 85% protection – it’s good to have some jammy blueberries peeking via the golden brown crumbly topping!

TIP: You probably have powdery streusel on the backside of the bowl, simply clench a pile of it in your fist to make it clump collectively. Then break up into clumps and scatter!

Bake for 65 minutes at 200°C/400°F (180°C fan-forced), rotating midway to make sure the streusel browns evenly.

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.
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
