About the ingredients
Method
Cake Preparation
- Heat the oven to 345°F instead of 350 to avoid crust overbrowning. Grease either a glass 10x15-inch pan or a deep-sided 9x13-inch metal one. The glass will slow baking; adjust times accordingly.
- Cream butter and 8 ounces softened cream cheese together for 2-3 minutes until very creamy—this step crucial for smooth batter. Then add brown and white sugar; beat till fluffy but not grainy, about 2-3 minutes more. Use a paddle attachment or hand mixer at medium speed to avoid overworking.
- Incorporate the two eggs one at a time, beating until just combined. Add vanilla extract; mix gently.
- Whisk flour, baking soda, powder, cornstarch, and salt in a separate bowl. Dry blend ensures even rise and tenderness from cornstarch. Add a third of this dry mix to wet batter, beat lightly, then half the buttermilk. Repeat with another third of dry and remaining buttermilk, then fold in the last dry portion carefully. Overmixing toughens cake—stop as soon as no flour pockets remain.
Layering Cake and Fillings
- Spoon half the thick batter into the pan. Use an offset spatula to get flat, even layer. Spread lemon filling over it but leave roughly 3/4-inch from the edges—important. If lemon seeps out, it chars during baking, turning bitter and unsightly.
- Top lemon filling with remaining batter, scooping from outer sides inward to contain lemon layer and prevent mixing. If batter resists smoothing on top, gently tap pan on counter to level.
Cream Cheese Filling Layer
- Whip together softened cream cheese, sugar, egg, lemon zest, and juice until uniform and soft but not runny. Spread this over top batter evenly. Should form distinct creamy topping.
Crumble Topping
- Combine flour, both sugars, and cinnamon. Pour in melted butter; stir with fork until mixture looks crumbly with no flour patches. If topping feels too dry, add a teaspoon more melted butter. Scatter generously over cream cheese layer.
Baking and Doneness
- Bake 60-75 minutes. After first 25 minutes, tent foil loosely atop cake to prevent too-dark crust. Glass pans hold heat differently; look for light golden edges and center that no longer jiggles if you give pan a gentle shake. Insert toothpick for moist crumbs, but not wet batter. Dense batter takes time; resist opening oven too often or it will sink.
- Let cake cool completely before glazing—warm glaze will slide off.
Glaze
- Mix powdered sugar with milk until drizzling consistency not too runny; drizzle in thin ribbons. Use less milk if glaze spreads too fast or disappears into cake.
- Chill glaze slightly but serve cake room temp. Keeps well covered in fridge for 2-3 days.
Pro Tips/Variations
- Substitute Greek yogurt for buttermilk (same volume) if out—adds tang and moisture, but batter thickens, adjust with splash water.
- Cream cheese in cake can be swapped for mascarpone for richer taste and less tang.
- If lemon filling too runny (store-bought curd varies), mix with 1 tsp cornstarch and heat to thicken before using.
- Overbeating eggs makes cake rubbery; add slowly and fold last flour carefully.
- For crunch, add chopped toasted pecans or almonds into crumble topping.
- Use glass thermometer probe if worried about doneness; internal temp should reach ~205°F for custardy center.
- If edges brown too fast, lower oven temp by 10-15 degrees and extend bake. Avoid opening door often; steam loss dries out crumb.
- To fix cracked top, sprinkle moisture with tiny splash water and cover loosely with foil after 40 minutes baking.
Cooking tips
Chef's notes
- 💡 Butter and cream cheese must be softened really well. Cold chunks wreck batter texture—clumps, uneven rise. Mix sugars gradually. Brown sugar keeps moisture; white sugar adds sweetness. Beat eggs slow, one at a time, or batter gets rubbery. Dry ingredients folded gently to not overdevelop gluten; stop when no flour pockets visible—no more. Use glass or metal pan adjusts bake times; glass slows heat, watch edges often. Temperature 345°F works better than 350°. Tent foil after 25 minutes to avoid crust burn but allow rise. Batter thick, won’t spread itself; offset spatula and tapping needed for smooth layers.
- 💡 Layer carefully. Lemon filling is acid and burns on edges if it seeps out. Leave 3/4-inch gap to sides—important detail I overlooked before. Pour half batter, spread gently, then spoon lemon filling. Top with remaining batter scooped from outer sides inward to seal lemon in. Cream cheese topping spread last, make sure ingredients room temp to avoid lumps or curdling. Crumble needs melted butter incorporated evenly; dry spots mean crumbly mixture falls apart baked. If crumble looks dry, add a teaspoon melted butter. Top cake generously but not packed tight; texture contrast is key here.
- 💡 Use jiggle test over timer. Center should have slight wobble but no liquid batter when shaken gently. Toothpick must come out with moist crumbs, not raw batter. Oven temps vary, environment changes; hot kitchen softens batter fast—work quickly. Wait for cake to cool fully before glazing or glaze will slide off—warm cake and glaze don’t combine well about runny mess. Powdered sugar glaze mixed to drizzling consistency; too much milk ruins it. Vanilla or almond milk work fine if dairy not handy. Chill glaze in fridge briefly, but serve cake at room temp to keep topping crisp and glaze stable.
- 💡 Try switching out buttermilk for Greek yogurt same volume; batter thickens so add splash water to loosen if needed. Mascarpone can replace cream cheese in cake layers if richer, less tang preferred. Lemon filling thickness varies wildly store-bought; if runny, stir in 1 teaspoon cornstarch and gently heat to thicken, cool before layering. Overbeating eggs ruins texture causing rubberiness; fold dry carefully last. Adding nuts toasted pecans or almonds in crumble adds crunch but mix dry for even baking. If edges brown too fast, lower oven 10-15 degrees and extend bake time—no shortcuts. Use probe for internal temp near 205°F for custard-like center but rely mostly on visual cues.
- 💡 If cake top cracks open—common issue—mist surface lightly with water and cover loosely with foil after 40 minutes baking. Keeps humidity and prevents further cracking. Glass pans require adjustment; monitor edges closely, they brown first. Learn batter feel—thick, creamy, not runny or stiff. Watch color changes, not clock alone. Let glaze drip in thin ribbons, never pour. Try vanilla milk in glaze for subtle aroma tweak. Store leftovers well sealed to keep crumble crunchy. Crumble topping and glaze need care, flour fully coated and glaze thin enough to hold on but not saturate.
Common questions
How soft should butter and cream cheese be?
Room temp but not melted. Too cold causes lumps, uneven mixing. If too warm, it gets greasy. Soft means soft to finger press, no chunks. Helps smooth buttery batter. Chill fixes if too soft—pop in fridge shortly.
Why add baking soda and powder?
Balance acidic lemon and buttermilk. Soda reacts quickly, powder gives extra lift slow. If only one used, cake falls or tastes off. Both improve rise and crumb. Skip or swap at your own risk.
What if lemon filling runs out edges?
Burns and chars, bitter taste. Leave 3/4 inch gap at edges, gentle scoop not to smash lemon in sides. If too runny, thicken with cornstarch before layering. Experiment with thickness.
Best way to store leftovers?
Cool completely first. Cover tightly to avoid drying crumb. Fridge keep crumble crunchy 2-3 days but can soften glaze. Freeze NOT great; crumble texture suffers. Warm before serving for softness.
