It may sound slightly faffy, but the best way to explain the tin size you need is to get one that is about 39 square inches in size. Nothing will be exact, but go for a similar bake time and give it a go! The baking time will only change by 1-2 minutes, and even if its slightly under the first time, you can always enjoy an incredibly delicious fudge brownie. I knew these would be intensely chocolatey, so I planned to make smaller, mini mousse cakes, both to control portions and for the cuteness factor. I thought these 3-inch spheres were the perfect serving size—enough to satisfy a big sweets craving, but not a ridiculous amount of mousse. And I love how the sphere shape makes them look even more space-themed!

Put the butter and chocolate chips into a mixing bowl. Microwave for 30 seconds, stir and repeat until the butter melts. Leave to stand for a minute or so then stir together until the chocolate has melted.Leave to cool slightly before adding the eggs. Add the caster sugar to the melted butter and chocolate and beat using an electric whisk for 2 minutes until pale and creamy. Secondly, melt the 2 bars of galaxy chocolate in the microwave and stir until it’s smooth in texture, then leave aside. The mixture of the brownies is simply mixed together in a bowl with a spatula so it’s incredibly easy – and then you pour them into your lined tin. I only ever tend to line the bottom of my tins, but I am a smidge lazy. I really hope you enjoyed today’s recipe and it got your creative juices flowing and inspired you to get baking too.I'm not gonna lie, I can't see myself making blondies any other way now. I'm actually obsessing over what chocolate bars I can do this with next! Oh, and you DEFINITELY want silicone, as opposed to traditional pans. Being able to flex the mold inside-out to remove the mousse is a must! chocolate chips – you can of course either leave these out, or swap up what chocolate chips or chunk flavours you use. Mars Bars are the ultimate nostalgic treat, so this recipe is a luxurious take on a comforting classic. I think these Mars Bars Brownies would be perfect served warm with a scoop of vanilla ice cream to cut through the richness. Or you could break pieces up and add them to an ice cream sundae.

Add the rest of the brownie batter over the top and level. Bake for 25-30 minutes or until the brownies still feel slightly squidgy in the middle. I set my air fryer to the regular air fry function, and baked for about 16 minutes. I have put the cook time as 14-16+ minutes because it may vary depending on how you like your brownies.

In a big bowl, mix together the soft butter and sugar until it's fluffy. Add the eggs one by one, stirring really well each time. Then, put in the vanilla extract.

Melt the butter and chocolate together in a large heavy-based pan. In a bowl or large wide-mouthed measuring jug, beat the eggs with the sugar and vanilla. Measure the flour into another bowl and add the salt.

Desert safe recipes use ingredients that are least likely to cause mold or spoilage. I wrote to the food science experts at BestFoodFacts.org and asked for their input. What's not to love about smooth Galaxy chocolate with an oozing caramel centre? Put that deliciousness into the centre of a blondie and you have baked goods on a whole new level. If you have an electric or stand mixer I recommend you use it for whisking the sugar and eggs into the blondie batter. This produces a really light and beautiful texture. As you’ll all know by now if your a long term reader of mine, when it comes to baking, I’m constantly looking for inspiration. I really find my creative juices flow when I’m looking through other bakers recipes. I went all-out with the galaxy theme, and decorated my mini mousse cakes with an assortment of gel food colors. I used swirls of navy, teal, purple, pink, and white colors (which are probably way more colorful than the actual Milky Way, let’s be real.) I finished them off with a pinch of edible silver star sprinkles, and they looked like miniature works of art. Completely edible, totally delicious works of art.
