Butter cake Thermomix sister wah (slight modification)

My family love plain old-school butter cake and I love to experiment with different brands in butter in the market. This time, I used @lescure_my butter and believe me, it smelt and taste heavenly! ❤️ Recipe is from 7 Days Perfection booklet that comes with your Thermomix, but I have made some adjustments to the recipe. - Butter Cake- // Ingredients: 250 g salted @lescure_my butter, softened (room temperature) and cut in cubes 150 g low GI brown sugar ½ tsp natural vanilla extract 5 eggs, A size 50 g fresh milk 250 g self-raising flour // Preparation: 1. Preheat oven to 170°C. Line a 20 cm x 20 cm square cake tin with baking paper. Set aside. 2. Crack eggs into a bowl, weigh in milk and vanilla extract. Set aside. 3. Pour brown sugar into mixing bowl. Mill at 10 sec, speed 10 and turn into icing sugar. 4. Insert butterfly whisk. Place butter and sugar in mixing bowl, beat 1 min 30 sec/speed 3.5. 5. Mix 40 sec/speed 3.5, adding vanilla extract, eggs one at a time and fresh milk through hole in mixing bowl lid onto rotating blades to beat the mixture into a smooth batter. 6. Add self-raising flour, mix 30 sec/speed 3. Remove butterfly whisk. 7. Transfer cake mixture to prepared square cake tin. 8. Bake for 30-45 minutes (170°C) or until a cake tester skewer or toothpick comes out clean when it is inserted in the centre of the cake. Allow to cool in cake pan for 10 minutes. Transfer to a serving plate and let cool completely. Cut and serve. I had 4 pieces at this morning for breakfast 🥲 So so good! It's the best butter cake I have made in history. It's fluffy, light and so buttery! Pair with a cup of kopi-O and half boil egg, and your day is complete 🥰.
