Gooseberry custard crumble cake is a vanilla butter sponge topped with thick stovetop custard, tart green gooseberries and a buttery crumble. It bakes in a 23 cm / 9-inch springform pan in 55 minutes and serves 10.
There’s something about a gooseberry in late June. Sharp first, then sweet. The custard softens that edge, and the crumble gives you something to bite into.
I bake this every summer when the farm stand puts out the first pints. The season is short, so I don’t wait.
One thing matters more than the rest. The custard has to be thick enough to hold a ribbon on the whisk. If it’s loose, it sinks into the sponge and the middle turns gummy. Cook it a minute longer than you think you need.
Why You’ll Love This Recipe
- Tart gooseberries cut through the sweet custard and sponge
- Stovetop custard sets reliably, so the layers stay put
- Bakes in one springform pan and slices cleanly
- Tastes good warm, room temperature or cold the next day
Ingredient Notes
- Gooseberries: Use firm green berries, topped and tailed with kitchen scissors. Frozen berries work straight from the freezer with no thawing, but the cake may need up to 5 extra minutes.
- Cornstarch: It thickens the custard and soaks up gooseberry juice so the layers stay separate. Don’t swap in more flour in the custard, it turns pasty.
- Whole milk: I use whole milk for both the custard and the batter. Oat milk works but gives a thinner custard, so cook it a minute longer.
- Unsalted butter: Use unsalted so you control the salt. Keep the crumble butter cold and the sponge butter soft, about 20 minutes out of the fridge.
Gooseberry Custard Cake with Crumble Topping
Ingredients
Method
- Warm 250 ml milk in a 2-quart / 1.9 L saucepan over medium heat until steaming, about 3 minutes. Whisk the 2 egg yolks, 40 g sugar and 2 tbsp cornstarch in a bowl until smooth, then pour in the hot milk in a slow stream while whisking.
- Pour the mixture back into the saucepan and cook over medium heat, whisking constantly, for 2 to 3 minutes until it bubbles. Keep whisking for 1 more minute until it holds a ribbon on the whisk. Off the heat, stir in 1 tsp vanilla and 15 g butter. Press plastic wrap onto the surface and cool until lukewarm, about 20 minutes, while you make the cake.
- Heat the oven to 175 C / 350 F. Grease a 23 cm / 9-inch springform pan and line the base with parchment. For the crumble, mix 100 g flour, 50 g brown sugar and a pinch of salt, then rub in 60 g cold butter with your fingertips until you have pea-sized clumps. Chill it in the fridge.
- Beat 115 g softened butter with 130 g sugar for 3 minutes until pale and fluffy. Beat in the eggs one at a time, then 1 tsp vanilla. Fold in the flour, baking powder and salt in two additions, alternating with the milk, until no dry streaks remain. Scrape the thick batter into the pan and smooth the top.
- Spread the lukewarm custard over the batter, leaving a 1 cm border at the edge. Toss the gooseberries with 30 g sugar and 1 tsp cornstarch, then scatter them over the custard in a single layer.
- Squeeze the crumble into clumps and scatter it over the fruit. Bake on the middle rack for 55 minutes, until the crumble is deep golden and the center barely moves when you nudge the pan.
- Cool the cake in the pan for 15 minutes. Run a knife around the edge, release the ring, and move the cake to a wire rack for 30 minutes more before slicing. The custard sets as it cools.
Notes
- Cook the custard until it holds a ribbon, then cool it under plastic wrap.
- Keep the crumble butter cold and chill the crumble while you make the batter.
- Don't skip the 45 minute cool, because the custard layer sets as it cools.
- Weigh the flour with a scale for an even sponge crumb.
Tips for Success
- Snip both ends off each gooseberry with kitchen scissors, which takes about 5 minutes for 300 g and keeps stems out of the cake.
- Whisk the custard constantly and keep cooking 1 minute after the first bubble, until it holds a ribbon on the whisk.
- Press plastic wrap directly onto the custard while it cools, so no skin forms and nothing needs sieving later.
- Spread the lukewarm custard to within 1 cm of the pan edge, so it doesn’t creep up the sides as the sponge rises.
- Squeeze the crumble into clumps with your fingers before scattering, which gives you chunky pieces instead of sandy dust.
Variations
- Swap half the gooseberries for rhubarb pieces cut to 1 cm, and add 1 tbsp extra sugar to the fruit.
- Stir 30 g rolled oats into the crumble for a chewier topping, and add a pinch of cinnamon.
- Add the zest of 1 lemon to the sponge batter to push the citrus note forward.
Storage and Reheating
Gooseberry custard crumble cake keeps for 3 to 4 days in the fridge, covered, once it has cooled completely. Because of the egg custard, don’t leave slices out for more than 2 hours.
The crumble softens in the fridge. To bring it back, warm a slice on a baking tray at 160 C / 325 F for 10 minutes. Or skip reheating and let a cold slice sit at room temperature for 30 minutes.
I don’t freeze this one. The custard turns grainy when it thaws. For make-ahead, prepare the custard a day early with plastic wrap on the surface, and keep the crumble in a jar in the fridge for up to 3 days.
Serving Suggestions
Serve gooseberry custard crumble cake warm with a pour of cold single cream or a scoop of vanilla ice cream. The cold dairy balances the sharp fruit.
For an afternoon table, cut thinner slices and serve them at room temperature with black tea or strong coffee.
A few raspberries on the side add color, and a light dusting of powdered sugar hides any cracks in the crumble.
FAQ
Why is the custard layer in my gooseberry crumble cake runny?
A runny custard layer means the custard wasn’t cooked long enough on the stovetop. Keep whisking until it bubbles, then cook one more minute, so it holds a ribbon on the whisk. Cool it under plastic wrap until lukewarm before spreading, because hot custard thins out and sinks into the batter.
Can I use frozen gooseberries instead of fresh in this cake?
Yes, use frozen gooseberries straight from the freezer without thawing them. Toss them with the sugar and cornstarch as written and scatter them over the custard. The cake may need up to 5 extra minutes in the oven, so wait until the center barely moves when you nudge the pan.
Can I bake gooseberry custard crumble cake the day before?
Yes, bake it a day ahead. Cool the cake fully, cover it, and refrigerate for 3 to 4 days. The crumble softens in the fridge, so warm a slice at 160 C / 325 F for 10 minutes to crisp it again. You can also make the custard one day ahead, with plastic wrap pressed on the surface.
What goes with gooseberry custard crumble cake?
Pouring cream or vanilla ice cream suits the tart gooseberries best, since cold dairy balances the sharp fruit. A cup of black tea or strong coffee works for the afternoon version. If the cake has been in the fridge, leave it out for 30 minutes so the custard loosens before serving.
Can I make gooseberry custard crumble cake gluten free?
Yes, swap in a 1:1 gluten-free baking flour that contains xanthan gum, for both the sponge and the crumble. The custard already uses cornstarch, so it needs no change. Expect a slightly denser sponge, and let the cake cool the full 45 minutes before slicing because gluten-free crumb is fragile when warm.
What’s the difference between gooseberry crumble and gooseberry custard crumble cake?
Gooseberry crumble is stewed or raw fruit under a crumble topping, served with a spoon. Gooseberry custard crumble cake adds a butter sponge base and a set custard layer, so it holds together and slices like a cake. It also bakes longer, 55 minutes, against the 35 to 40 minutes a fruit crumble usually takes.
