Bake me a cake!

Question

This is a cake:

_========_
|        |
+________+
|        |
+________+
|        |
+________+

It is 8 wide, 3 tall, and 1 deep.

You must write a program that makes a cake from 3 inputs. The first input controls how many underscores there are in the middle and =s on the top. Here's the first cake with a width of 10 instead of 8:

_==========_
|          |
+__________+
|          |
+__________+
|          |
+__________+

The second input controls how tall the cake is. Here's the second cake with a height of 4 instead of 3:

_==========_
|          |
+__________+
|          |
+__________+
|          |
+__________+
|          |
+__________+

Note the repetition of the layers.

The third input controls how deep it is. That just how many | |s to include on the top. Here's the third cake with a depth of 2 instead of 1:

_==========_
|          |
|          |
+__________+
|          |
+__________+
|          |
+__________+
|          |
+__________+

You can print trailing whitespace. Test cases:

Input: 3, 3, 3

Output:

_===_
|   |
|   |
|   |
+___+
|   |
+___+
|   |
+___+

(I hope I never get this cake)

Input: 3, 2, 1

Output:

_===_
|   |
+___+
|   |
+___+

Input: 5, 5, 5

Output:

_=====_
|     |
|     |
|     |
|     |
|     |
+_____+
|     |
+_____+
|     |
+_____+
|     |
+_____+
|     |
+_____+

Thanks to @nmjmcman101 for saving three bytes, and reminding me of an old operator that saved another two bytes.

Explanation:

a, b, and c are the three arguments.

2é_                   " Insert two '_' characters
   Àé=                " Insert 'a' '=' characters between them
      Ù               " Duplicate this line

         è            " *Hollow* this line (replace all the middle characters with spaces)

             È_       " *Hollow* this line again, but use '_' instead of spaces

In fact, using the uppercase variant, È<char> can probably save some more bytes in a few other places too. Thanks for reminding me! :) \$\endgroup\$

Try it online!

How?

ṬṚ;⁹RḤṬḤ¤Wµ^9ẋ⁵;@;µZị“_+= |”Y - Main link: depth, height (width is a program argument)
Ṭ                             - untruth   [0,0,0,...1] such that the length is the depth
 Ṛ                            - reverse   [1,0,0,...0]
        ¤                     - nilad followed by link(s) as a nilad:
   ⁹                          -   link's right argument, height
    R                         -   range   [1,2,3,...,height]
     Ḥ                        -   double  [2,4,6,...,2*height]

         W                    - wrap in a list
          µ                   - monadic chain separation, call that c
           ^9                 - bitwise XOR c with 9 [8,9,9,...,9,9,11,9,11,9,11,...,9,11]
              ⁵               - program's 3rd argument, width
             ẋ                - repeat the augmented c width times
               ;@             - concatenate with a copy of c
                 ;            - concatenate a copy of c
                  µ           - monadic chain separation call that sideways cake
                   Z          - transpose the sideways cake to put it the right way up
                     “_+= |”  - literal ['_','+','=',' ','|'] (cake decoration)
                    ị         - index into (1 based and modular, so 8,9, and 11 are, mod 5,
                                            3, 4, and 1 yielding '=', ' ', and '_')
                            Y - join with new lines
                              - implicit print

Java 7, 169 164 158 bytes

String f(int...a){String s="_",t="|",u="+";for(;a[0]-->0;s+="=",t+=" ")u+="_";s=s+"_";t="\n"+t+"|";u=t+"\n"+u+"+";for(;a[2]-->1;)s+=t;for(;a[1]-->0;)s+=u;return s;}

Try it online!

Ungolfed:

String f(int...a)                    // saves two bytes over int a, int b, int c
{
    String s="_", t="|", u="+";      // set up the start of each row

    for(; a[0]-->0; s+="=", t+=" ")  // Uses the goes-to operator to fill the row
        u+="_";                      

    s += "_\n";                      // adds the end of each row
    t += "|\n";              
    u = t + u + "+\n";               // and combining t into u

    for(; a[2]-->1; )                // add the top of the cake
        s += t;

    for(; a[1]-->0; )                // add the rest of the cake
        s += u;

    return s;
}

You can save 1 byte by putting u=t+u+"+\n" inside the for-loop: for(u=t+u+"+\n;a[2]-->1;)s+=t;`. But nice answer, +1 from me. — Kevin Cruijssen, Commented Oct 30, 2017 at 12:43

\$\begingroup\$ 1. Using @ on each line and after do is slightly shorter than @echo off. 2. @call set w=%%w%%_ avoids setlocal enabledelayedexpansion. 3. Use @for /l %%p in (2,1,%2). 4. IMHO you should add @set w= so that the code works more than once. \$\endgroup\$

\$\begingroup\$ 1. Your @for /l %%p in (1,1,%1)do seems to have gone missing. 2. Your cake seems to be the wrong height, at least it doesn't seem to match the test case when I try it. 3. If you run the script twice in the same command session then the cake just gets wider and wider. \$\endgroup\$

\$\begingroup\$ Great! Just a few last things I noticed: 1. You don't need the @ after the &. 2 If you change the second loop to (2,1,%3) and the third loop to (1,1,%2) then I think you can delete the echo +%w%+ line. 3. If I've counted correctly, then I think you should fill w with spaces instead of _s, as that will result in fewer substitutions. (I would use @call set w= %%w%% as otherwise the space is hard to spot!) \$\endgroup\$

\$\begingroup\$ @recursive Usually it's allowed and nowhere does the question force the ordering and the 2nd most voted answer reorders the inputs and probably has been seen by the OP, so I'd assume it's fine. \$\endgroup\$

JavaScript/ES6, 90 bytes

I just wrote a rough solution, and happened to beat the existing JS answer by a whopping 56 bytes. Then I golfed off 11 bytes.

(w,h,d,g=a=>a+a[1][r='repeat'](w)+a[0]+`
`)=>g('_=')+(l=g('| '))[r](d-1)+(l+g('+_'))[r](h)

Here's a demo.

var F = (w,h,d,f=a=>a+a[1][r='repeat'](w)+a[0]+`
`)=>f('_=')+(l=f('| '))[r](d-1)+(l+f('+_'))[r](h);

console.log(F(prompt('width') || 3, prompt('height') || 3, prompt('depth') || 3));
console.log(F.toString().length);
