Vi laver et sødt fyld til tærten, fordi min mor ikke vil have den helt tør.

In Danish, lave is the usual verb for making or preparing something, especially food.

So: Vi laver et sødt fyld = We are making/preparing a sweet filling

By contrast, gøre is more like do in many other contexts, not usually for cooking or preparing a dish.

For example: lave mad = cook / make food
lave en kage = make a cake

Because fyld is a neuter noun in Danish.

With an indefinite singular neuter noun, you use:

• et as the article
• -t on the adjective

So: et sødt fyld

Compare:

• en sød tærte = a sweet pie
• et sødt fyld = a sweet filling

This is a very common Danish pattern.

Because tærten means the pie, while tærte by itself is just pie as a dictionary form.

For common-gender nouns, Danish usually adds -en to make them definite:

• en tærte = a pie
• tærten = the pie

So the sentence is talking about a specific pie, not just any pie.

Here til means something like for or meant for.

So: et fyld til tærten = a filling for the pie

This is the natural Danish way to express the idea that the filling belongs with the pie.

If you said i tærten, that would focus more on something being inside the pie. That can make sense in some contexts, but with fyld the usual phrase is fyld til noget.

Because fordi introduces a subordinate clause.

In the sentence: Vi laver et sødt fyld til tærten, fordi min mor ikke vil have den helt tør.

the part after fordi gives the reason.

A useful detail: in modern Danish, this comma is often seen, but depending on comma style, it can also be omitted. So the comma before fordi is very common and completely normal, but you may sometimes see sentences without it.

Because after fordi, Danish normally uses subordinate clause word order.

In a main clause, you would usually say: Min mor vil ikke have den helt tør.

But after fordi, the sentence adverb ikke normally comes before the finite verb: fordi min mor ikke vil have den helt tør

So this is a classic contrast:

• Main clause: Hun vil ikke...
• Subordinate clause: ... fordi hun ikke vil...

Not really. In this sentence, vil have means want.

So: min mor ikke vil have den helt tør
means: my mother doesn’t want it completely dry

This is a very common Danish structure:

• Jeg vil have kaffe = I want coffee
• Han vil have den blå = He wants the blue one

So ville + have often expresses wanting, not future tense.

Den refers to tærten.

Since tærte is a common-gender noun, the pronoun is den:

• en tærte → den

If it referred to a neuter noun, you would use det:

• et fyld → det

So here: min mor ikke vil have den helt tør
means that she does not want the pie completely dry.

Because tør describes den, which refers to tærten, and tærte is a common-gender singular noun.

So the adjective stays in its basic form:

• den er tør = it is dry

If it referred to a neuter noun, you would get -t:

• det er tørt

That means:

• tærten er tør
• fyldet er tørt

Also, helt just means completely or entirely here. It does not change the adjective ending.

Yes. You can say:

Fordi min mor ikke vil have den helt tør, laver vi et sødt fyld til tærten.

That is perfectly natural.

But when the fordi clause comes first, the main clause changes word order:

• Vi laver ... becomes
• ... laver vi ...

This is the normal Danish verb-second pattern in main clauses. Once something else comes first, the verb comes before the subject in the main clause.
