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!

As part of my $21 Challenge to use all the food in the pantry, I have set up a 'use up soon' basket containing items getting close to their use-by date. This way, I will remember to use things before I have to throw them out.

I grow most of our vegetables to eat healthy and save money. I save all scraps to compost and I wanted a tumble composter. They turn lawn clippings and scraps into compost in 14 to 21 days. The composter is priced at $410. I bought a 240 litre plastic drum (cherry bin) from the local trash and treasure market for $5.00. My husband drilled holes in the lid. It doesn't have a frame but I roll it on the lawn for five rotations once a day and I make compost in 21 days. It isn't hard to roll but I can't empty it into a wheel barrow (I'm only five feet tall) so I spread a sheet of plastic on the lawn and tip it out onto that. The compost is fantastic.

My husband was dying of lung cancer. He wanted his ashes scattered at sea and, being a practical man, discussed other details. He did not think much of church services and a eulogy delivered by a person he did not know.

He died in my arms at home and the next morning he was picked up by Sommerville Funerals. (Most people are unaware that they may have some time with their loved one before the body is collected.) A private cremation was arranged and I collected my husband's ashes for his 'celebration of life' at our home. All our friends arrived, charged their glasses, sat or stood on our front lawn and listened to his story that I had written a few days before. We played his favourite music and people stayed all day. My husband loved a great party and this was no exception. Everyone said this was the best service they had ever attended and they were going to do the same.

Incidentally, the only cost was the private cremation fee. Nothing like some of the very high fees I was quoted.

I can hardly believe it but we have an extra $2000 sitting in our savings account! I have been a stay at home mum for 18 months. My husband earns a slightly above average salary, which allows me to stay at home with our son. We have a modest home, with modest furnishings and modest tastes. We haven't really had a financial plan since we got married two and a half years ago and have just been cruising along, saving a bit some months and spending it other months.

When I first left work I had full intentions of making a budget, planning our meals, organising our lives and generally being on the ball with our finances. Each month when pay day rolled around, I would say 'this is the month where I get organised!' But it never happened. I am the first to admit that I have been lazy, unmotivated, complacent and ostrich-like. I have been a member of Simple Savings for over a year and always thought we were doing OK and didn't really need to know all these ways to save money. I had heard of the $21 Challenge but wasn't really motivated to try it and we were ticking along as usual - until last month.

With baby number two arriving in three months we needed extra storage space so we extended our garage to make room for all our stuff. This extension made a dent in the savings account which although we knew it would, was quite depressing to see the balance dropping and dropping and not going back up. Lo and behold, motivation began creeping in!

I downloaded all our bank transactions for the month and was horrified to find that I had spent an average of nearly $260 per week on groceries for two adults and one toddler. There were lots of other things I was also horrified to see but I started with the groceries as it seemed easiest. Motivation knocked harder. I decided to take charge!

I read the first two chapters of the $21 Challenge on the website, put a copy of the book on my library request list and did a stocktake of my pantry, fridge and freezer. Imagine my shock when I discovered I had enough ingredients to plan meals for the next 19 days! That's not counting meals like scrambled eggs, pumpkin soup and the emergency baked beans on toast. We had enough food in the house to live on for over three weeks! We just needed fresh fruit and veges and that was about it. I didn't quite make $21 but my first grocery shop after doing the stocktake came to $61, down from $258 per week the previous month.

From then on I watched the bank account like a hawk and knew where every cent went. In previous months when the bank account got low, I would simply pull out the credit card and pay it off on pay day but not this month! This month it stayed in my wallet.

It's pay day again tomorrow and guess what? I have spent an average of $160 per week on groceries, saving us nearly $100 per week. By being aware and thinking to myself 'do I really need that?' and deciding 'no', the savings account has increased by a whopping $2250! That figure makes me weak at the knees! I can’t honestly say where the money has been going before now. We don’t have the latest gadgets, appliances or clothing. I am truly at a loss BUT I have to say I'm pretty proud of myself right now! At the same time, I feel a bit sick that I didn't do this 18 months ago, or even 12 or 6 months ago, but I've done it now. I am motivated to change my ways. I have goals. I have the energy to do this and I have Simple Savings to thank for giving me the tools to continue saving. THANK YOU!

I feed my family of six on a little over $230 a fortnight with a bit of planning and a lot of baking! I buy a bulk 2kg pack of beef mince from Aldi ($11) and a 2kg pack of chicken ($20) as well as jars or packs of sauces. I separate the mince into four 500g lots and make rissoles with one lot (adding grated carrot and zucchini), then I put the rest away for spaghetti, pasta bake and burrito/taco night. This makes four main meals and we often have leftovers for lunch the next day.
I take three or four of the chicken breasts and slice them in half or into thirds, tenderise them with a mallet and cook them for sandwiches. I slice and dice the rest of the chicken for stir fries, casseroles, wraps and burritos. This gives me another four or five main meals plus leftovers. This way I spend around $230 on my main shop a fortnight, including nappies. I bake a lot which cuts back on the cost of expensive snacks for the children and I always have a pack of jelly on hand to 'treat' them when the cupboards are really bare
I also plan my meals around what fresh veggies I have in the fridge and leave the frozen ones until after I have run out of fresh ones, and I alternate rice and pasta with couscous and potatoes or cauliflower bake.
It just goes to show that frugal and planning don't have to mean boring!

My husband and I have began saving up to $30 per week on our grocery bill since we invented 'Grandma's Day!' When we go to the supermarket we ask ourselves, 'would Grandma have been able to buy this item in her day 60+ years ago?' If the answer is no, then we decide we don't need to buy it either! This saves us money on a whole range of items such as fancy dips, designer coffees and biscuits. We used to pay over $3 for a pack of 10 biscuits, now I can make 12 biscuits for around $1. Using plain yoghurt as a base we are even making our own dips; there are so many websites with great dip ideas. Now we are saving valuable money and our waistlines too!

When someone you know has a baby, it can be hard to choose a gift that will be appreciated – but this gift is always well received!

I like to give new parents the gift of dinner for a week, which is delivered each night. In the weeks leading up to the due date, I cook and freeze meals that will feed my family and theirs. It gives the new parents one less thing to worry about as they are settling in with their baby, and ensures they are not living on takeaway food.

I make things like pasta sauce, casseroles, soup and garlic bread. Roast dinners and chicken salads are easy to make fresh in large amounts and I also bake cakes and biscuits so they have something to offer their visitors. If they have school age kids, I even give them food for their lunchboxes such as slices of cake, sandwiches, pizza rolls and muffins.

This may not be as spectacular as a large gift with a bow, but all my friends say that it was their best gift, as they are so tired by the afternoon that the last thing they want to think about is cooking dinner.

I have slashed my grocery bill, kept my kids from grazing AND lost five kilos, simply by enjoying a bigger breakfast. Breakfast items are generally cheaper if you are careful how you shop. Plain brand muesli, Vita Brits, porridge and cornflakes are all cheap items to have in your pantry. Plain brand yoghurt, fruit (canned or fresh) and vegetables are also fairly cheap, as well as tuna on toast. The helpings are generous and we eat until we are full. I've found that over the course of the day, hunger pains are gone, snacking is unnecessary and we eat smaller portions for lunch and dinner. Our savings have been made especially on dinner; we find that we don't eat as much meat and it takes a lot less to satisfy us at night. Not only have the kids stopped grazing, they have better concentration at school, eat all of their dinner because its a smaller portion and have stopped that afternoon dash for sugar, chips and treats. The kids enjoy eating the bigger breakfast because they are really hungry in the morning, as opposed to eating a heavier meal at night when they are tired and fussy and likely not to eat much. Since changing our biggest meal from dinner to breakfast, I've lost five kilos in four weeks and our grocery bill has gone down by at least $30 a week. I can also bulk cook dinner and make them stretch even further now. I look and feel great, am saving money and my family is happier too!

I make this vegetable pasta sauce for three reasons - it's cheap and healthy and it uses up leftover vegies (cooked and uncooked) so I save three times!

Whenever I serve up a dish of vegies for dinner (usually broccoli, carrots, beans and zucchini in my house) and it isn't all eaten, I put the leftovers in a ziplock bag and throw it in the freezer. Then, when my fresh vegies are starting to get to that 'oh dear' stage, I start cooking!

In a big pot, with a bit of olive oil, I fry onion and garlic and add all the 'oh dear' vegies - sometimes there is a fiddly bit of broccoli that is too small to use in a meal or carrots that are starting to wilt. Other vegies I have added include celery, cauliflower, broad beans, spinach, cabbage and capsicum. I chop and cook all of this - in summer I add fresh tomatoes, in winter I throw in a couple of cans of Home Brand tinned tomatoes. To this I add the frozen leftover vegies, a squeezie stock concentrate or stock cube and some water.

I cook the whole lot until everything is soft, and then I blitz it in a food processor or with a Bamix until it looks like pasta sauce. I then freeze this in meal-size portions and use it for everything - I add it to mince for bolognese, or just use it neat. My kids don't know it's full of vegies - they just think it's another jar of commercial pasta sauce!
