Fifteen items and an hour and fifteen minutes, in one 8x4 loaf pan.
Three separate mixtures go into this: a batter, a rubbed crumble and a thin icing. Only the first two see the oven.
Why This Recipe Works
- Zest and juice together give lemon both aroma and tartness.
- Milk keeps a butter loaf batter loose enough to hold whole fruit.
- Folding raspberries in last leaves them whole rather than crushed to purée.
- Cold butter rubbed into flour and sugar makes a coarse crumble, not a paste.
- A thin icing over the crumb top drizzles between the streusel rather than hiding it.
Ingredient Notes
- Fresh raspberries
- One cup, whole. Folded in at the end so they stay whole in the crumb rather than breaking down into streaks.
- Lemon zest and juice
- A tablespoon of zest and two of juice in the batter, plus another tablespoon of juice in the icing.
- Flour, brown sugar and cold butter
- A third of a cup, a quarter cup and three tablespoons. Rubbed together they make the coarse streusel top.
- Powdered sugar
- Half a cup, whisked thin with lemon juice. Drizzled so the crumb underneath stays visible.

Three Mixtures, One Pan, and a Loaf Rather Than a Cake
The name says cake and it is baked as a loaf - thick slices with a rubbled top, no layers and no frosting. What follows is three separate mixtures made in sequence, two of which bake together and one of which arrives an hour later.
Stage 1 of 5
The batter - lemon TWICE, and MILK to loosen it
Steps 2–2 of 6
1 3/4 cups FLOUR, 1 tsp baking powder, 1/2 tsp salt, 1/2 cup softened BUTTER, 3/4 cup SUGAR, 2 EGGS, 1 tbsp LEMON ZEST, 2 tbsp LEMON JUICE and 1/2 cup MILK. The zest and the juice are not redundant: lemon oil lives in the peel and carries almost all of the aroma, while the juice brings the acidity. The milk matters structurally - a stiff butter batter crushes whole fruit as it is folded, and this one stays loose enough to take the berries without breaking them.
- Batter made with lemon zest, juice and milk, raspberries folded inMake cake batter with flour, baking powder, salt, butter, sugar, eggs, lemon zest, lemon juice, and milk; fold in raspberries.
Stage 2 of 5
1 cup of WHOLE raspberries, FOLDED in last
Steps 2–2 of 6
Whole matters: you want intact red berries suspended in a pale yellow crumb, not a swirled purée. Folded gently and last is how they stay that way - stirred in early, or beaten, they collapse and bleed streaks through the batter. A few will break regardless and that is fine; the intention is that most do not.

Stage 3 of 5
The crumble - COLD butter, RUBBED
Steps 3–3 of 6
1/3 cup FLOUR, 1/4 cup BROWN SUGAR and 3 tbsp of COLD BUTTER RUBBED TOGETHER and scattered over the loaf. Cold is the entire technique. Rubbed cold, the butter stays in small solid pieces coated in flour and bakes into a COARSE GOLDEN STREUSEL; softened or melted, it binds everything into a paste that spreads into a flat sweet layer. This streusel is a defining component the title never names.
- Crumble rubbed together and scattered over the loafRub the crumble ingredients together and scatter over the loaf.
Stage 4 of 5
50 to 55 minutes - a long bake for a deep pan
Steps 4–4 of 6
At 350°F UNTIL SET, then COOLED COMPLETELY. An 8x4 loaf is a deep, narrow shape and it takes far longer than a round tin of the same batter - the middle is a long way from every surface. Cooling completely is required by what comes next rather than being a courtesy: a thin icing hitting a warm crumb top soaks straight through and leaves nothing visible.
- Baked fifty to fifty-five minutes until set, cooled completelyBake 50 to 55 minutes until set; cool completely.
Stage 5 of 5
The icing - thin, and OVER the crumb
Steps 5–6 of 6
1/2 cup POWDERED SUGAR whisked with 1 tbsp LEMON JUICE - the third and last appearance of lemon in this recipe - and DRIZZLED OVER THE CRUMB TOP. Thin and drizzled rather than spread, so it runs into the gaps between the streusel and leaves the rubbled texture showing. Then SLICED AS A LOAF CAKE. FRESH RASPBERRIES and a LEMON WEDGE alongside, as part of the serving.
- Thin lemon icing whisked and drizzled over the crumb topWhisk powdered sugar and lemon juice into a thin icing and drizzle over the crumb top.

Success Tips
- Fold the raspberries in gently at the very end so they stay intact.
- Keep the crumble butter cold; warm butter makes a paste rather than crumbs.
- Cool completely before icing, or a thin drizzle disappears into the crumb.
Serving Ideas
Ten thick slices of a loaf with a pale yellow crumb holding whole raspberries, a coarse golden streusel top drizzled with thin white icing, with fresh raspberries and a lemon wedge alongside.
Frequently Asked Questions
Is this a layer cake?
No. It is a loaf-shaped cake baked in an 8x4 pan and cut into thick slices — crumb-topped rather than layered or frosted.
Should the raspberries be crushed in?
No. They go in whole and are folded gently at the very end, so the finished slice shows whole berries rather than a pink swirl.
Why does my crumble come out as a paste?
Almost always warm butter. It needs to be cold when it is rubbed into the flour and brown sugar, or it binds into dough instead of crumbs.
