LOLA’S CUPCAKES
LOLA’s is a business with a simple aim: to handcraft the most delicious cupcakes you have ever tasted, using only the finest fresh ingredients. LOLA’s is run with passion and creativity by Asher Budwig, a fourth-generation baker who grew up watching his father Mario establish and run the enormously successful chain Millie’s Cookies, which grew to over 100 stores in the UK. Asher’s grandmother and great grandmother had also run a patisserie and café since the 1940s in Colombia, so with such a talented family of bakers, it was almost inevitable that he would bring success to LOLA’s.
LOLA’s is rapidly expanding, and Asher’s passion for high standards and quality ingredients is reflected in the latest developments. In every new branch of LOLA’s, quality remains key. The specialist bakers are highly trained and passionate about all things LOLA. Each individual cupcake is created with love and skill, so that every cupcake is sure to impress.
In this book, we want to let you in on some of our secrets, and share our favourite recipes that have made LOLA’s so successful. All the best-loved cupcakes from LOLA’s Classic Collection are included here, so you can create our famous Chocolate, Vanilla and Red Velvet cupcakes at home. With advice on achieving cake perfection and a guide to piping our signature swirl of frosting, you will be creating professional-looking morsels in no time.
Once you’ve mastered our Classic Collection, you will be ready to try your hand at some of our more unusual cupcakes. These include some of our unique LOLA’s specialities – Maple Syrup, Peanut Butter, Banoffee, Raspberry Pavlova and Apple Crumble never fail to please. For grown-up palates, there is an array of cocktail-inspired delights, such as Cosmopolitan, Mojito and Pina Colada, as well as a luxurious selection of decadently rich chocolate bakes, such as Chocolate Chilli, Dark Chocolate Truffle and Chocolate Mint.
Although cupcakes are our first and foremost passion at LOLA’s, we also love to experiment with other cakes and bakes. We’re baking fanatics and we are always trying out new ideas, so for this book we decided to give you some of our favourite large cake recipes, as well as our much-loved traybakes and bars. We just had to include Chocolate Fudge Cake, Summer Victoria Sponge and a Chocolate Traybake, among others. They are too irresistible not to share with you all!
If you are after something completely different, you’ll love our final chapter with its unique savoury selection. Cheese and herbs work perfectly in muffin-style recipes, and our creative cooks have developed some unusual combinations using pesto, cream cheese, sun-dried tomatoes and other ingredients that will really leave your tastebuds tingling.
The enduring popularity of the cupcake knows no bounds, and they remain the most stylish of bakery treats. Their versatility is what makes them so successful, from simple classics that are perfect with afternoon tea or mid-morning coffee to extravagantly decorated creations that make delightful gifts at any time of year. With something at LOLA’s for every occasion, what are you waiting for? Get your apron on and get baking!

A LIGHT AND FLUFFY, MOIST CHOCOLATE CAKE TOPPED WITH OUR DELICIOUS CHOCOLATE BUTTERCREAM AND DECORATED IN A FUN STYLE. A GREAT BASIC RECIPE WITH WHICH YOU CAN EXPERIMENT.
3 eggs
220 g/1 cup caster/granulated sugar
150 ml/⅔ cup sunflower oil
80 ml/⅓ cup full-fat/whole milk
150g self-raising flour/1 cup cake flour mixed with 2 teaspoons baking powder, sifted
45 g/generous ⅓ cup unsweetened cocoa powder
BUTTERCREAM
150 g/1¼ sticks butter
40 g/⅓ cup unsweetened cocoa powder
300 g/2½ cups icing/confectioners’ sugar
60–75 ml/4–5 tablespoons full-fat/whole milk
TO DECORATE
chocolate stars and sprinkles of your choice
muffin pan lined with 12 muffin cases
piping/pastry bag fitted with a large star nozzle/tip
MAKES 12
Preheat the oven to 180°C (350°F) Gas 4.
Place the eggs and sugar into the bowl of a stand mixer fitted with a whisk attachment (or use an electric whisk and large mixing bowl), and beat the mixture at medium to high speed for 1–2 minutes, until light and fluffy.
If using a stand mixer, switch to the paddle attachment. Combine the oil and milk, then slowly add to the egg mixture, and mix until just combined. Sift the flour and cocoa powder together into a separate bowl, and add to the batter, a little at a time, beating until incorporated. Scrape down the side of the bowl with a rubber spatula, and briefly beat at high speed until the mixture is smooth. Do not over-mix.
Using an ice cream scoop, divide the mixture between the muffin cases, filling to almost two-thirds full. Bake in the preheated oven for 20–25 minutes, until well risen and a skewer inserted into the cakes comes out clean. Transfer to a wire rack to cool completely.
For the buttercream, place the butter into the bowl of a stand mixer fitted with a paddle attachment (or use an electric whisk and large mixing bowl), and beat the mixture at medium to high speed, until smooth and soft. In another bowl, sift the cocoa powder and icing/confectioners’ sugar together. Turn the mixer to low speed and add the sifted cocoa powder and sugar, a little at a time, to the butter. When it is incorporated, turn the mixer to medium speed and add the milk, a tablespoonful at a time, until the buttercream is smooth. Beat on high speed, until light and fluffy. If the buttercream is too stiff, add a little more milk to soften.
To decorate, spoon the buttercream into the piping/pastry bag, and pipe a swirl onto the tops of the cupcakes. Alternatively, spread the buttercream onto each cake using a palette knife or metal spatula. Decorate each cupcake with a chocolate star and some sprinkles.
rocky road cupcake
THE ROCKY ROAD CUPCAKE HAS IT ALL! SQUIDGY MARSHMALLOWS, SOUR CHERRIES, CRUNCHY BISCUIT PIECES, TOASTED ALMONDS AND SILKY BUTTERCREAM.
ROCKY ROAD
50 g/3½ tablespoons butter
125 g/¾ cup chopped dark/bittersweet chocolate
1 tablespoon golden/light corn syrup
75 g/¾ cup crumbled digestive biscuits/graham crackers
40 g/¾ cup mini marshmallows
40 g/¼ cup dried sour cherries, chopped
40 g/⅓ cup toasted flaked/sliced almonds
18-cm/7-in square cake pan, greased and lined with baking parchment
CHOCOLATE CAKE
1 egg
75 g/6 tablespoons caster/granulated sugar
50 ml/¼ cup sunflower oil
2 tablespoons full-fat/whole milk
1 tablespoon unsweetened cocoa powder
50 g self-raising flour/⅓ cup cake flour mixed with ½ teaspoon baking powder
30 g/½ cup chopped marshmallows
40 g/⅓ cup dried sour cherries
VANILLA CAKE
90 g/¾ stick butter
125 g/⅔ cup caster/granulated sugar
2 eggs
½ teaspoon vanilla bean paste
100 g self-raising flour/¾ cup cake flour mixed with 2 teaspoons baking powder
½ teaspoon baking powder
85 ml/⅓ cup sour/soured cream
BUTTERCREAM
200 g/2 sticks minus 2 tablespoons butter
400 g/3½ cups icing/confectioners’ sugar
½ teaspoon vanilla bean paste
6–10 teaspoons full-fat/whole milk
2 tablespoons unsweetened cocoa powder
muffin pan lined with 12 muffin cases
piping/pastry bag fitted with a large star nozzle/tip
MAKES 12
Preheat the oven to 180°C (350°F) Gas 4.
To make the rocky road, place the butter, chocolate and syrup in a saucepan. Heat gently until melted. Set aside to cool slightly. Place the biscuit/cracker crumbs, marshmallows, cherries and almonds in a large bowl, and pour over the chocolate mixture. Mix with a wooden spoon, then pour into the prepared pan. Chill in the refrigerator for at least an hour, until set.
To make the chocolate cake mixture, place the egg and sugar into the bowl of a stand mixer fitted with a whisk attachment (or use an electric whisk and large mixing bowl), and beat the mixture at medium to high speed for 1–2 minutes, until light and fluffy.
If using a stand mixer, switch to the paddle attachment. Combine the oil and milk, then slowly add to the egg mixture, and mix just until combined. Sift the cocoa powder and flour into a separate bowl, and add to the batter, a little at a time, beating until incorporated. Scrape down the side of the bowl with a rubber spatula, and briefly beat at high speed until the mixture is smooth. Do not over-mix. Add the marshmallows and cherries, and fold in, using the rubber spatula.
For the vanilla cake, place the butter and sugar into the bowl of a stand mixer fitted with a paddle attachment (or use an electric whisk and large mixing bowl), and beat for 30 seconds, until light and fluffy. Add the eggs and vanilla bean paste, and mix at low speed until combined. Sift the flour and baking powder into a separate bowl, and add to the batter, a little at a time, beating at low speed until incorporated. Add the sour/soured cream and mix until smooth. Do not over-mix.
Divide the vanilla batter evenly between the muffin cases. Do the same with the chocolate batter, placing it on top of the vanilla mixture already in the cases. Using the tip of a knife, swirl the two batters together to blend them slightly. Bake in the preheated oven for 20–23 minutes, until well risen and a skewer inserted into the cakes comes out clean. Transfer to a wire rack to cool completely.
For the buttercream, place the butter into the bowl of a stand mixer fitted with a paddle attachment (or use an electric whisk and large mixing bowl), and beat until soft and fluffy. Divide the butter evenly between two bowls. Sift half the icing/confectioners’ sugar into one bowl, and slowly mix until combined. Add the vanilla bean paste and enough of the milk to achieve a consistency suitable for piping. Sift the rest of the icing/confectioners’ sugar into the other bowl along with the cocoa powder, and slowly mix until combined. Add enough of the milk to achieve a consistency suitable for piping.
Spoon the vanilla buttercream down one side of the piping/pastry bag and spoon the chocolate buttercream down the other side. This will create a marbled effect when piped.
Turn the rocky road out onto a chopping board. Using a sharp knife, slice it into at least 24 small pieces.
Pipe the buttercream onto each cake in a swirl. Some cakes will have more chocolate buttercream and others will have more vanilla, which makes each cupcake individual. Top each cupcake with a couple of pieces of rocky road.
