We all know how convenient it is to grab a packet of cake mix off the supermarket shelf, but you can save a lot of money by making your own. This recipe is really easy to make and you can store it in the fridge for up to three months or for longer in the freezer.

Ingredients:

250g self raising flour
185g caster sugar
2tbsp milk powder, skimmed or full cream
125g butter

Method:

Sift or process all dry ingredients until combined, and then rub in or process the butter.

To make the cake add:

2 eggs
1tsp vanilla essence
1/2 cup water

When these ingredients have been added to the cake mix, beat the whole lot until combined. Bake at 150C - 180C for 30 minutes if making one cake, or 20 minutes for smaller cakes. For variety, add coffee, cocoa or anything else you like. This is as good as shop bought cake mixes and half the price!

After reading every newsletter on this fantastic website, I decided to make changes to our household budget.

I started by rummaging through the cupboard, where I found an insulated plunger coffee mug that my husband and daughter had given me as a gift. The mug had never been used as I found it easier to grab a 'latte to go' on the way to work. I bought a tin of ground coffee beans for $6.65, figuring that this tin, with its plastic lid, could be refilled. I now keep this tin in the fridge at work. So, instead of buying three lattes a week at $3.50 each, I now allow myself one a week or sometimes just one a fortnight.

While buying my latte I would sometimes purchase an English muffin with bacon and egg. I now have muffins in the freezer, bacon rashers trimmed and have perfected the three minute poached egg. The bacon takes one minute in the microwave and the muffin is toasted in no time. If I am in a hurry, I wrap the bacon and egg muffin in a small piece of alfoil and take this to work. So instead of paying $14 per week, or $672 per year, I now buy the ingredients for the equivalent of $1.45 per week, saving just over $600 per year. Wow!

You have no idea of how proud I feel. I have saved so much money and it's thanks to your wonderful site.

I’ve saved countless dollars on expensive gourmet ice cream by getting creative with the cheaper varieties. My kids love it when I buy them what they call 'special' ice creams. These are the expensive varieties that come in exotic flavours and cost between $7.00 and $9.00 for a two-litre tub! Needless to say, they really are a rare treat. However, during the school holidays, my kids and I became gourmet ice cream chefs! Using a four-litre tub of Home Brand vanilla ice cream (that cost $4.59), we scooped it out of the tub and let it sit at room temperature for a few minutes. Then we mixed green food colouring, a couple of drops of peppermint essence and some chocolate chips into the softened ice cream to create our very own Mint Choc Chip flavour! We placed it in an airtight container and popped it back in the freezer to enjoy later. The kids were so excited to have made their own special ice cream that we have since concocted many different ‘gourmet’ flavours just by adding ingredients from the pantry.

My husband and I have become '30 Day Gourmets' and enjoy both the savings and the extra time we spend together as a result! We recently looked into 'Once a Month Cooking', which we were interested in because neither of us really enjoys cooking tea when all we really feel like doing is relaxing after being at work.

After gathering ideas of how the scheme works (literally - you cook once a month!), we thought we would try it by cooking for a fortnight first. We gathered recipes from the Internet and raided the recipe books (the recipe must be able to be frozen) and came up with such things as marinated chicken, curried sausages, spaghetti sauce, apricot chicken and all kinds of things.

We then picked a Sunday, turned up the stereo and did nothing but cook! It turned out to be a really enjoyable day. Once cooked and cooled, the food is put into freezer bags or takeaway containers (which cost almost nothing) and frozen. What we thought would last two weeks actually lasted three!

Each night, I would take out a container or bag for the next night and leave to defrost in the fridge. We then dragged out the steamer, threw in all the vegetables and once a week cooked up a big pot of rice. We would then have a small portion of meat (which also lowers fat-intake levels), have a pile of yummy steamed vegies and a little rice - the result being full bellies, smiling faces and very minimal washing up!

This not only saved us money but also time. Usually groceries cost us $150 for two weeks. With the cost of buying meat and grocery items needed for the cook-up ($100) and in-between buyings of vegetables once a week ($10), we spent a total of $130 when we would have spent over $150. (This is because at each shop we would grab things we liked, but didn't really need). Having a selection of meals already cooked for the weeks ahead feels great!

At first a big cook-up seems difficult if you aren't motivated, but you can start small and next time you are cooking something that would freeze well, cook double or triple the recipe and freeze excess. I also went to the local library and got out some books on freezer cooking which also had suitable recipes in them.

My husband and I honestly can't believe how we survived before our cook-ups and love the idea of actually doing things we want to each night, rather than being a slave to the kitchen!

NB - A book from the library which was a big help in planning recipes was 'The Freezer Cooking Manual from 30 Day Gourmet'. The '30 Day Gourmet' book is available on eBay and from most bookstores.

I have turned my love of a good bargain into something far more valuable! Whenever I am tempted to buy something I could possibly do without, I first calculate how much we would save by paying that money into our mortgage instead. For example, I recently saw a new dress on sale for $49.99 - a bargain, right? However, I paid a quick visit to a mortgage calculator website and discovered that if I didn't buy the dress and put that money onto our mortgage instead, it would take a whole month off the loan term and save us $334.39c in interest. In other words, my 'bargain' dress would really cost me over $300!

Looking at my purchases this way has become a really easy and effective way to curb my spending habit. Now I carry a piece of paper in my wallet with various prices on and I can see how much I would really be spending. It's amazing how much stronger my willpower becomes when I check my piece of paper before buying something and find out what its real cost is!

Smaller portions means larger savings, as you'll see in this hint.

After having a little money left over from a gift voucher, I purchased a set of three small loaf tins. (each tin holds 1/3 of a normal cake mix). I made up a chocolate cake mix and baked it in three tins. I kept one cake aside and put two in the freezer as soon as they were cold. This meant the cake lasted three days instead of just one. I remove the bar cake from the freezer each morning and not long after the kids are enjoying their smaller slices of cake, with no complaints.

I have since carried this over to savoury dishes. When I make meatloaf, I put the mixture into one large tin as well as the three smaller tins. We eat the larger meatloaf for dinner and I freeze the other ones for lunches. This is working really well for me and the savings are huge.

Here is a hint that has saved our family time, money and arguments, not to mention countless wasted scraps of paper. This year we purchased a large diary for family use, labelled it 'Bench-top Notes' and sat it on our bench. In this diary we write notes to each other that in the past, would have been on scrap pieces of paper that would often be missed or mislaid. Anything from appointment reminders, details of missed phone calls, housework or instructions for our teenage boys, or just simple but personal notes to each other such as 'Hi sweetie, have a great day, I love you, see you at 5.30!' and so on! It has tidied up our bench-top, kept us all organised and an added bonus is that we can look back on our entries for confirmation of bills being paid, appointments kept or cancelled with the reason why and smile at the little love notes to and from each other. This diary cost about $12 but it now contains the priceless and lifetime memories of our 'Bench-top Notes'.

School holidays are more affordable with the help of the $21 Challenge! Money seems to slip away so effortlessly while out having fun with my teenage kids. Budgeting is something I am trying to teach them about but it is hard to make it relevant sometimes. Then I had a great idea that would make them pro-active with the weekly budget over the holidays, without me being a 'budget nag'.

It is the $21 Challenge week, with a twist. THEY have to go and log all the food in the freezer and pantry, and make up the meal plan for the week. Then all the money THEY save us for the week can go towards some guilt-free fun. It's a great incentive and my kids are learning important household skills.

I add a supermarket gift card to my weekly grocery list and use them all up to shop for Christmas! After doing some calculations I realised that the ready-made Christmas hampers that you pay for weekly cost three times their actual value, not to mention the fact that they can include many products you won't ever use. My new system for buying Christmas groceries lets me buy my own hamper full of items at the current price or on special.

I pay myself to exercise! Now, you may wonder how that actually saves me money. Because my exercise is free, usually walking with a friend or working out to DVDs I've received as gifts, I don’t have to buy expensive exercise clothes or pay for a gym membership. And paying myself to exercise? That gives me motivation. I started with $1.00 for every day I exercised, and increased it to $2.00 a day - still cheaper per week than a single exercise class or gym membership! I wait until I have enough money for a facial or massage, and treat myself.

I find that the end goal of some pampering really works as an incentive to keep exercising. Prior to this, I never let myself splurge on those sort of things. I am now happier, healthier and far more relaxed!
