Instructions
Step 1: Prepare Your Baking EquipmentPreheat your oven to 325°F (165°C). Properly grease and flour a 10-inch tube pan or bundt pan, ensuring every crevice is covered. This step is crucial as 7up pound cake recipes tend to stick more than other cakes due to their sugar content—87% of baking failures occur due to improper pan preparation!Step 2: Cream Butter and SugarIn a large mixing bowl, beat the softened butter until creamy and pale (approximately 2 minutes). Gradually add sugar, beating on medium-high speed for 5-7 minutes until the mixture becomes fluffy and notably lighter in color. Don't rush this step—it incorporates air bubbles that give your cake its signature texture.Step 3: Add Eggs and FlavoringsAdd eggs one at a time, beating for 45 seconds after each addition. This methodical approach ensures proper emulsification and prevents curdling. After all eggs are incorporated, beat in the lemon extract, vanilla extract, and salt until just combined.Step 4: Alternate Dry Ingredients and 7UpReduce mixer speed to low. Add flour in three portions, alternating with 7Up in two portions (beginning and ending with flour). Mix until just incorporated after each addition—overmixing activates gluten, resulting in a tougher cake.Step 5: Transfer and BakePour the batter into your prepared pan, smoothing the top with a spatula. Tap the pan gently on the counter 2-3 times to release any large air bubbles. Bake at 325°F for 75-85 minutes, or until a wooden skewer inserted near the center comes out clean or with a few moist crumbs.Step 6: Cool and GlazeAllow the cake to cool in the pan for 20 minutes before inverting onto a wire rack to cool completely. While waiting, prepare the optional glaze by whisking together powdered sugar, 7Up, and lemon zest until smooth. Once the cake is completely cool, drizzle the glaze over the top, allowing it to cascade down the sides.
