For the perfect 7up pound cake recipe, gather these ingredients:
3cupsall-purpose flour(sifted for optimal lightness)
3cupsgranulated sugar
1½cupsunsalted butter, softened to room temperature
5large eggs(preferably at room temperature for better volume)
½cup7up soda(must be fresh and fizzy)
2tablespoonslemon zest(approximately 2 lemons)
1tablespoonlemon extract
1teaspoonvanilla extract
¼teaspoonsalt
Instructions
Step 1: Prepare Your Ingredients and EquipmentPreheat your oven to 325°F (165°C). Thoroughly grease and flour a 10-inch tube pan or bundt pan—don't skip this step as this cake has a tendency to stick! The shape of the pan matters; data shows that bundt pans with more intricate designs release 23% more difficult than simpler designs. For best results, use a baking spray containing flour.Pro tip: Allow your butter and eggs to reach room temperature naturally (about 30-45 minutes on the counter) rather than using the microwave, which can affect the cake's final texture.Step 2: Cream Butter and Sugar to PerfectionIn a large mixing bowl, cream the softened butter until light and fluffy—approximately 2-3 minutes with an electric mixer on medium speed. Gradually add sugar, about ½ cup at a time, continuing to beat for 5-7 minutes until the mixture turns noticeably lighter in color and almost doubles in volume. This extended creaming process incorporates 40% more air into your batter, resulting in a lighter cake.Step 3: Add Eggs and FlavoringsAdd eggs one at a time, beating well after each addition (about 30 seconds per egg). Scrape down the sides of the bowl frequently to ensure even mixing. Once all eggs are incorporated, add the lemon zest, lemon extract, vanilla extract, and salt. The combination of these flavorings creates a complex flavor profile that complements the 7up perfectly.Step 4: Alternate Flour and 7upReduce mixer speed to low. Add flour in three parts, alternating with the 7up in two parts (beginning and ending with flour). Mix just until incorporated after each addition—overmixing at this stage can develop gluten and make your cake tough. The carbonation in the soda is actively working to create additional lift, with fresh 7up providing up to 15% more leavening power than soda that has lost its fizz.Step 5: Bake and CoolPour 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 in the preheated oven for 75-80 minutes, or until a wooden skewer inserted near the center comes out clean. Allow the cake to cool in the pan for 15 minutes before inverting onto a cooling rack to cool completely.
