Some pairs just work: Peanut butter and banana, chocolate and caramel, raspberry and white chocolate. We can’t deny it, we certainly love all these combinations! But then, of course, there are also combinations that aren’t baked as often but can be just as good. You know, those odd couples, where after the first bite, you ask: “Why did I never think of this?” One such example is chocolate and lemon. It’s super delicious, as our chocolate lemon sheet cake proves. Check out our recipe to get to know the magic of this unlikely duo.
Our Chocolate Lemon Sheet Cake Recipe
Are you baking for a lot of hungry mouths but still want to try something new? That works out well because our chocolate lemon sheet cake exactly meets those requirements. With its three layers, it not only looks great but is guaranteed to please everyone at the table, both young and old dessert lovers won’t be able to get enough.
Making our chocolate lemon sheet cake isn’t as complicated as it may appear. So let’s go layer by layer, quite literally. The base is a simple chocolate shortbread dough, which you knead together from flour, butter, sugar, cocoa, and some melted dark chocolate. Press this into a pan and let it chill it for a while. Meanwhile, you can start on the lemon batter. This is a simple batter that you will flavor with lemon juice and zest. It’s important that you use organic fruit here, as these are not sprayed with pesticides.
Spread the batter over the chocolate base and top everything with a wonderfully fresh cream cheese layer. This will melt during baking and fuse with the cake, making it just as creamy as it is chocolatey and lemony. Once the cake as fully cooked, take it out of the oven, let it cool, and spread grated chocolate on top. Doesn’t it look great? And even better: It tastes as good as it looks! With the first bite, you’ll already be looking forward to the next one. And the next. And the next.
If, against all expectations, there are any leftovers, our chocolate lemon sheet cake will easily stay fresh for two to three days. It even tastes, dare we say, better on the second day. If you want to freeze leftovers, cut the cake into pieces and wrap them individually. It will stay nice and moist even after thawing.
